The answer to 32z - 48 using factoring is 3/2.

Given,

32z - 48

We have to find the answer using factoring:

Factoring:

Finding things to multiply together to produce an expression is known as factoring. It is comparable to splitting an expression into numerous smaller expressions.

Here,

32z - 48 = 0

Add 48 to both sides

32z - 48 + 48 = 0 + 48

32z = 48

Divide 32 on both sides

32z/32 = 48/32

z = 48/32

Now, we can factorize 48/32

Take 2 as common factor

(48/2) / (32/2) = 24/16

Again, take 2 as common factor

(24/2) / (16/2) = 12/8

Now, take 4 as common factor

(12/4) / (8/4) = 3/2

Here, z = 3/2

That is, the answer for 32z - 48 using factoring is 3/2.

Answer:

17%

Step-by-step explanation:

Hello!

Out of the 6 options, only 1 option will be correct. This can be represented as a ratio of 1:6.

If you randomly guess, there is an equal chance of choosing any of the 6 options.

To find the percentage of guessing the correct option, simply divide 1 by 6 (1 option is correct out of 6), and multiply the outcome by 100 (for percentage).

The probability of getting an answer correct would be 17%.

The probability of getting an answer wrong would be 83%, which can be found by subtracting 17% from 100%.

Based on the population density of the area in 1980 and the area, the population in 1980 was 807,750 people

The population density of an area is based on the population of the area and the area. The formula is:

Population density = Population of area / Surface area

Given that the surface area is 750 square miles and the population density in 1980 was 750 square miles, the population of the area can be found by the formula:

Population in 1980 = Population density in 1980 x surface area

By taking the quotient between the total debt and what they earn in a sold-out show, we conclude that they need to sell a total of 7 sold-out shows.

10:

A discount of 30%. Correct option is B.

Answering part 9:

We know that they asked for a loan of $8,000, such that an interest of the 6% is applied to this, so the total amount that they need to return is:

$8,000*(1 + 6%/100%) = $8,000*(1.06) = $8,480

Now we know that the theater has 150 seats, and each ticket costs $8.50, so for every sold-out show they earn a total of:

T = 150*$8.50 = $1,275

Then the number of sold-out shows that they need is given by the quotient:

$8,480/$1,275 = 6.65

Rounding to the next whole number we get to 7. To cover the debt, they need to sell a total of 7 sold-out shows.

10. The original price is $180 and she pays $126, then the discount k is:

$180*k = $126

k = $126/$180 = 0.7

and 1 - 0.7 = 0.3

So the discount is of the 30%.

Step-by-step explanation:

[tex]\frac{x+2}{3}[/tex] - [tex]\frac{2x-4}{2}[/tex] = 0

multiply through by 6 ( the LCM of 3 and 2 ) to clear the fractions

2(x + 2) - 3(2x - 4) = 0 ← distribute parenthesis on left side and simplify

2x + 4 - 6x + 12 = 0

- 4x + 16 = 0 ( subtract 16 from both sides )

- 4x = - 16 ( divide both sides by - 4 )

x = 4

------------------------------------------------------------

[tex]\frac{5x}{2}[/tex] + [tex]\frac{x-2}{8}[/tex] = 2 ( multiply through by 8 to clear the fractions )

4(5x) + x - 2 = 16

20x + x - 2 = 16

21x - 2 = 16 ( add 2 to both sides )

21x = 18 ( divide both sides by 21 )

x = [tex]\frac{18}{21}[/tex] = [tex]\frac{6}{7}[/tex]

-----------------------------------------------------------

[tex]\frac{x-5}{4}[/tex] - [tex]\frac{3x-1}{5}[/tex] = - [tex]\frac{3}{2}[/tex]

multiply through by 20 ( the LCM of 4, 5, 2 ) to clear the fractions

5(x - 5) - 4(3x - 1) = - 30 ← distribute parenthesis on left side and simplify

5x - 25 - 12x + 4 = - 30

- 7x - 21 = - 30 ( add 21 to both sides )

- 7x = - 9 ( divide both sides by - 7 )

x = [tex]\frac{9}{7}[/tex]

-------------------------------------------------------------

[tex]\frac{1}{x-1}[/tex] + [tex]\frac{1}{x+1}[/tex] = [tex]\frac{4x+2}{x^2-1}[/tex] ← x² - 1 is a difference of squares , then

[tex]\frac{1}{x-1}[/tex] + [tex]\frac{1}{x+1}[/tex] = [tex]\frac{4x+2}{(x-1)(x+1)}[/tex]

multiply through by (x - 1)(x + 1) to clear the fractions

x + 1 + x - 1 = 4x + 2

2x = 4x + 2 ( subtract 4x from both sides )

- 2x = 2 ( divide both sides by - 2 )

x = - 1

If we substitute this value back into the original equation, we find

[tex]\textsf{3.} \quad x=\dfrac{9}{7}[/tex]

[tex]\textsf{4.} \quad \textsf{No solution}[/tex]

Step-by-step explanation:

Given equation:

[tex]\dfrac{x+2}{3}-\dfrac{2x-4}{2}=0[/tex]

[tex]\textsf{Add \; $\dfrac{2x-4}{2}$ \; to both sides of the equation}:[/tex]

[tex]\implies \dfrac{x+2}{3}-\dfrac{2x-4}{2}+\dfrac{2x-4}{2}=0+\dfrac{2x-4}{2}[/tex]

[tex]\implies \dfrac{x+2}{3}=\dfrac{2x-4}{2}[/tex]

Cross multiply:

[tex]\implies 2(x+2)=3(2x-4)[/tex]

[tex]\implies 2x+4=6x-12[/tex]

Subtract 2x from both sides:

[tex]\implies 2x+4-2x=6x-12-2x[/tex]

[tex]\implies 4=4x-12[/tex]

Add 12 to both sides:

[tex]\implies 4+12=4x-12+12[/tex]

[tex]\implies 16=4x[/tex]

[tex]\implies 4x=16[/tex]

Divide both sides by 4:

[tex]\implies \dfrac{4x}{4}=\dfrac{16}{4}[/tex]

[tex]\implies x=4[/tex]

--------------------------------------------------------------------------

Given equation:

[tex]\dfrac{5x}{2}+\dfrac{x-2}{8}=2[/tex]

Multiply the numerator and denominator of the first fraction by 4:

[tex]\implies \dfrac{5x \cdot 4}{2\cdot 4}+\dfrac{x-2}{8}=2[/tex]

[tex]\implies \dfrac{20x}{8}+\dfrac{x-2}{8}=2[/tex]

[tex]\textsf{Apply the fraction rule} \quad \dfrac{a}{c}+\dfrac{b}{c}=\dfrac{a+b}{c}:[/tex]

[tex]\implies \dfrac{20x+x-2}{8}=2[/tex]

[tex]\implies \dfrac{21x-2}{8}=2[/tex]

Multiply both sides by 8:

[tex]\implies \dfrac{(21x-2) \cdot 8}{8}=2 \cdot 8[/tex]

[tex]\implies 21x-2=16[/tex]

Add 2 to both sides:

[tex]\implies 21x-2+2=16+2[/tex]

[tex]\implies 21x=18[/tex]

Divide both sides by 21:

[tex]\implies \dfrac{21x}{21}=\dfrac{18}{21}[/tex]

[tex]\implies x=\dfrac{18}{21}[/tex]

Reduce the fraction by dividing the numerator and denominator by 3:

[tex]\implies x=\dfrac{18 \div 3}{21 \div 3}[/tex]

[tex]\implies x=\dfrac{6}{7}[/tex]

--------------------------------------------------------------------------

Given equation:

[tex]\dfrac{x-5}{4}-\dfrac{3x-1}{5}=-\dfrac{3}{2}[/tex]

Multiply the numerator and denominator of the first fraction by 5, and the numerator and denominator of the second fraction by 4:

[tex]\implies \dfrac{(x-5) \cdot 5}{4\cdot 5}-\dfrac{(3x-1)\cdot 4}{5\cdot 4}=-\dfrac{3}{2}[/tex]

[tex]\implies \dfrac{5x-25-12x+4}{20}=-\dfrac{3}{2}[/tex]

[tex]\implies \dfrac{-7x-21}{20}=-\dfrac{3}{2}[/tex]

Cross multiply:

[tex]\implies 2(-7x-21)=-3(20)[/tex]

[tex]\implies -14x-42=-60[/tex]

Add 42 to both sides:

[tex]\implies -14x-42+42=-60+42[/tex]

[tex]\implies -14x=-18[/tex]

Divide both sides by -14:

[tex]\implies \dfrac{-14x}{-14}=\dfrac{-18}{-14}[/tex]

[tex]\implies x=\dfrac{18}{14}[/tex]

Reduce the fraction by dividing the numerator and denominator by 2:

[tex]\implies x=\dfrac{18 \div 2}{14 \div 2}[/tex]

[tex]\implies x=\dfrac{9}{7}[/tex]

--------------------------------------------------------------------------

Given equation:

[tex]\dfrac{1}{x-1}+\dfrac{1}{x+1}=\dfrac{4x+2}{x^2-1}[/tex]

Factor the denominator of the fraction on the right side of the equation:

[tex]\implies \dfrac{1}{x-1}+\dfrac{1}{x+1}=\dfrac{4x+2}{(x+1)(x-1)}[/tex]

Multiply the numerator and denominator of the first fraction by (x+1), and the numerator and denominator of the second fraction by (x-1):

[tex]\implies \dfrac{x+1}{(x+1)(x-1)}+\dfrac{x-1}{(x+1)(x-1)}=\dfrac{4x+2}{(x+1)(x-1)}[/tex]

[tex]\textsf{Apply the fraction rule} \quad \dfrac{a}{c}+\dfrac{b}{c}=\dfrac{a+b}{c}:[/tex]

[tex]\implies \dfrac{x+1+x-1}{(x+1)(x-1)}=\dfrac{4x+2}{(x+1)(x-1)}[/tex]

[tex]\implies \dfrac{2x}{(x+1)(x-1)}=\dfrac{4x+2}{(x+1)(x-1)}[/tex]

Multiply both sides by (x+1)(x-1):

[tex]\implies \dfrac{2x(x+1)(x-1)}{(x+1)(x-1)}=\dfrac{(4x+2)((x+1)(x-1)}{(x+1)(x-1)}[/tex]

[tex]\implies 2x=4x+2[/tex]

Subtract 4x from both sides:

[tex]\implies 2x-4x=4x+2-4x[/tex]

[tex]\implies -2x=2[/tex]

Divide both sides by -2:

[tex]\implies \dfrac{-2x}{-2}=\dfrac{2}{-2}[/tex]

[tex]\implies x=-1[/tex]

However, if we substitute x = -1 into the original equation we get:

[tex]\implies \dfrac{1}{(-1)-1}+\dfrac{1}{(-1)+1}=\dfrac{4(-1)+2}{(-1)^2-1}[/tex]

[tex]\implies -\dfrac{1}{2}+\dfrac{1}{0}=\dfrac{-2}{0}[/tex]

One possibility for resolving the inequality is (20, 60) in which x represents the number of tacos sold, and y the number of burritos sold

When graphing inequalities, the dependent variable, or y, is placed on the left side of the equation, while the other variables are placed on the right side.

The parameters are as follows:

Hudson has enough ingredients to make 90 tacos.

Each taco costs $3 to purchase.

Each burrito costs $7 to purchase.

Hudson must sell $420 worth of tacos and burritos per day.

x = number of tacos sold

y = the number of burritos sold

We need to graphically represent and solve the system of inequalities, and to identify one possible solution

The inequalities in the system are as follows:

x + y ≤ 90

3·x + 7·y ≥ 420

We have the following graphs to plot the above inequalities:

y ≤ 90 - x

y ≥ 420/7 - 3·x/7

y ≥ 60 - 3·x/7

The vertices of the feasible region's triangle are as follows from the inequality graph:

(0, 90), (0, 60), and the third vertex is found as follows for accuracy;

90 - x = 60 - 3·x/7

x = 52.5

y = 90 - x

∴ y = 37.5 at the vertex

The third vertex is (52.5, 37.5)

The interest rates required to get a total amount of $2,420 from compound interest on a principal of $2,000 compounded 1 times per year over 2 years is 10% per year.

The interest on savings that is calculated on both the initial principal and the interest accrued over time is known as compound interest.

The concept of compound interest, also known as "interest on interest," is thought to have first appeared in Italy in the 17th century. It will accelerate the growth of a sum more quickly than simple interest, which is calculated only on the principal sum.

Money is multiplied more quickly through compounding, and the more times it is compounded, the higher the compound interest will be.

Using the formula A = P(1 + r/n)^nt

Solving for rate r as a decimal

r = n[(A/P)^(1/nt) - 1]

r = 1 × [(2,420/2,000)^{1/(1)(2)} - 1]

r = 0.1

Then convert r to R as a percentage

Answer:

95% of adult males have diastolic blood pressure readings that are at least 102 mmHg

Step-by-step explanation:

The empirical rule states that for a normal distribution, nearly all of the data will fall within three standard deviations of the mean . The empirical rule is further illustrated below

68% of data falls within the first standard deviation from the mean.

95% fall within two standard deviations.

99.7% fall within three standard deviations.

From the information given, the mean is 80 mmHg and the standard deviation is 11 mmHg.

2 standard deviations = 2 × 11= 22

80+ 22= 102 mmHg

Therefore, 95% of adult males have diastolic blood pressure readings that are at least 102 mmHg.
