(PLEASE HELP ME)

Which of the following number sentence is true?
A. 35/5 = -7

B. -72/9 = 8

C. -48/-12 = -4

D. -65/-13 = 5

Answer:

A. length = 23 cm; width = 5 cm

Step-by-step explanation:

So if 4 times the width would be [tex]4w[/tex] and 3 more than would be [tex] + 3[/tex], the equation would be [tex]l = 4w + 3[/tex]. If the perimeter is 56, then the new equation, [tex]2(4w + 3) + 2(w) = 56[/tex] can be formed. This simplifies to [tex]8w + 6 + 2w = 56[/tex], then to [tex]10w + 6 = 56[/tex], then to [tex]10w = 50[/tex], and finally, [tex]w = 5[/tex]. So the width is 5, and now plug it into the first equation.

[tex]l = 4(5) + 3[/tex], becomes [tex]l = 20 + 3[/tex], becomes [tex]l = 23[/tex].

So the dimensions are: length = 23 cm, width = 5 cm.

*And just to be sure, [tex]2(23 + 5) = 2(28) = 56[/tex] which is correct.

Step-by-step explanation:

Answer:

B and C

Step-by-step explanation:

First you have to find a common denominator which would be 18. Then you need to multiply the denominators to get to 18. 6x3 and 9x2. Now whatever you do to the bottom you have to do to the top. So you would mutiply 5x3 and 7x2. The fractions you are left with are, 14/18 and 15/18.

To solve the problem we need to know about fractions.

A fraction is a way to describe a part of a whole. such as the fraction [tex]\frac{1}{4}[/tex]can be described as 0.25.

Given to us

To bring the denominator, we need to take the LCM of the denominator, therefore,

[tex]\dfrac{5}{6},\ \dfrac{7}{9}[/tex]

we know that the LCM of 6 and 9 is 18. therefore,

[tex]=\dfrac{(5\times 3)}{(6\times 3)},\ \dfrac{(7\times 2)}{(9\times 2)}\\\\=\dfrac{15}{18},\ \dfrac{14}{18}[/tex]

Given:

The expression is

[tex]2\log c+3\log k[/tex]

To find:

The value after condense the logarithm.

Solution:

We have,

[tex]2\log c+3\log k[/tex]

Using properties of logarithm, we get

[tex]=\log c^2+\log k^3[/tex]            [tex][\because \log x^n=n\log x][/tex]

[tex]=\log (c^2k^3)[/tex]            [tex][\because \log (ab)=\log a+\log b][/tex]

Therefore, the required value is [tex]\log (c^2k^3)[/tex].

10

Step-by-step explanation:

3x° + 46° +14°

3*10° + 46 + 14° =90

therefore the value of x is 10

The value of x on the given figure is 10.

Option D is the correct answer.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

From the figure,

3x + 46 + 14 = 90

Now,

Simplifying.

3x + 60 = 90

Subtracting 60 on both sides.

3x = 90 - 60

3x = 30

Dividing 3 into both sides.

x = 10

Thus,

The value of x on the given figure is 10.

Answer:

[tex]-\frac{3}{2} , 5[/tex]

Step-by-step explanation:

The zeroes of a function are the x values of the points at which the graph intersects the x-axis. All points on the x-axis have a y-value of 0, therefore, we need to find out which values of x can be plugged in to have the result be 0. This function is already factored out. So, for each expression, find which input of x makes the result equal 0.

1) So, start with 2x + 3. Set it equal to 0 and solve for x:

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

Therefore, [tex]-\frac{3}{2}[/tex] is one of the zeroes.

2) Next, set x-5 equal to 0 and solve, too:

[tex]x - 5 = 0 \\x = 5 \\[/tex]

Therefore, 5 is one of the zeroes.

3) Thus, the zeroes are [tex]-\frac{3}{2}[/tex] and 5.

Rise over Run

Step-by-step explanation:

The slope and y-intercept values indicate characteristics of the relationship between the two variables x and y. The slope indicates the rate of change in y per unit change in x. The y-intercept indicates the y-value when the x-value is 0.

Answer:

y=-1500x + 21000

Step-by-step explanation:

I =PRT

I = interest

P = principal

R = interest rate%

T = time

The straight-line depreciation equation would be; y=-1500x + 21000

An equation is an expression that shows the relationship between two or more numbers and variables.

Given that car that Sophia wants to buy costs $21,000. She does research that after 14 years the car depreciates to a value of zero.

The standard exponential equation is [tex]y = a(1-r)^t[/tex]

r is the rate

t is the time

a is the initial value

Given the following;

r = 12% = 0.12

t = 14 years

a = $21000

Substitute;

y = 21000(1 -0.12)^14

y = $1500

Therefore, the straight-line depreciation equation would be;

y=-1500x + 21000

Answer:

1.1 * 10 ^ -3

Step-by-step explanation:

Given the value of the thivkness of a dollar bill to be 0.0011metre

The standard scientific notation is expressed as A * 10^n

A is any value between 1 and 10 where n is any integer

0.0011 = 11/10000

0.0011 = 11 *1/1000

0.0011 = 11 * 0.0001

0.0011 = 1.1 * 0.001

0.011 = 1.1 * 10 ^ -3 (Note that the decimal point is shifted forward three times and the power is negative because the value is less than 1)

Answer:

20 comic books

Step-by-step explanation:

Let us first set up a variable, x, for the number of books that Zoe has. If Jared has 12 more comics than Zoe, he would have x+12 books.

Given that Zoe and Jared have a total of 28 comic books, let us write an equation and solve for x:

[tex]x+x+12=28\\2x+12=28[/tex]

Now that we have a simplified version of the equation, let us solve for x by isolating the variable on the left side:

[tex]2x=28-12\\2x=16\\x=8[/tex]

We now know that x=8, and also that Jared has x+12 books. To find the number of comic books Jared has, let us add 12 to x:

[tex]x+12=\\8+12=\\20\\[/tex]

Therefore, Jared has 20 comic books.
