solve for x. 7(x+2)=6(x+5)
Answer:
16
Step-by-step explanation:
7x+14=6x+30
Move x into one side and whole numbers to the other.
Solve like linear equation.
7x+14=6x+30
7x-6x=30-14
x=16
Answer:
x = 16
Step-by-step explanation:
7(x+2)=6(x+5) multiply
7x + 14 = 6x + 30 add like terms
7x - 6x = 30 - 14
x = 16
Solve the equation,
3(b + 3) - 4(-2+b) = 19
Answer:
b= -2
Step-by-step explanation:
Answer:
b = -2
Step-by-step explanation:
The first thing we need to do to solve this equation is expand the brackets. To so this we need to multiply the outside term with each of the terms inside the bracket (distributive law).
This gives us:
3xb + 3x3 -4x-2 -4xb = 19
Which multiplies out to:
3b + 9 + 8 -4b = 19
Combine like terms:
-b +17 = 19
From here we move the 17 to the other side by subtracting 17 from both sides
-b +17 -17 = 19 - 17
-b = 2
Divide both sides by -1:
-b/-1 = 2/-1
Which gives us:
b = -2

is 4 to 7 the same as 7 to 4? Explain why or why not.
Answer:
No, 4 to 7 is not the same as 7 to 4.
Order is important when writing a ratio.
The ratio compares the first quantity to the second.
The ratio 4 to 7 means there are more of the second quantity, but 7 to 4 means there are more of the first.

100000 inches is equal to how many miles?
Answer:1.5783 Miles
1.5783 Miles
Step-by-step explanation:
Multiply the value in Inch (in) by 0.0000157828 (the conversion factor). So,
100000 Inch (in) × 0.0000157828 = 1.57828 Mile.

Step-by-step explanation:
Is the following relation a function ? S = {(1,2),(2,2),(-2,2)} justify your answer
Answer:
YESStep-by-step explanation:
relation is a function if we have y for every x from domain and for one x we have one and only one y
x = 1 --> y = 2
x = 2 --> y = 2
x = -2 --> y = 2
no x-es without y-es
and no two the same x-es with one y
so this relation is a function
Its pitcher is shaped like a cylinder with a radius of 1 centimeter and a height of 7.8 cm. What's this pitcher plant's approximate volume?
Answer:
The pitcher plant's approximate volume is 24.492 [tex]\text{cm}^{3}[/tex].
Step-by-step explanation:
We are given that a pitcher is shaped like a cylinder with a radius of 1 centimeter and a height of 7.8 cm.
Let the radius of a cylinder = r = 1 cm
and the height of a cylinder = h = 7.8 cm
As we know that the volume of a cylinder is given by;
The volume of a cylinder = [tex]\pi r^{2}h[/tex]
= [tex]3.14 \times 1^{2} \times 7.8[/tex] {taking approximate value of [tex]\pi[/tex] to be 3.14}
= [tex]3.14 \times 7.8[/tex]
= 24.492 [tex]\text{cm}^{3}[/tex]
Hence, this pitcher plant's approximate volume is 24.492 [tex]\text{cm}^{3}[/tex].

using appropriate properties, find the value of 249² - 248²
Answer:
[tex]\boxed{\bold{\huge{\boxed{497}}}}[/tex]
Step-by-step explanation:
=> [tex]\sf 249^2 - 248^2[/tex]
Using Formula [tex]\sf a^2 - b^2 = (a+b)(a-b)[/tex]
Where
a = 249
b = 248
=> [tex]\sf (249+248)(249-248)[/tex]
=> [tex]\sf (497)(1)[/tex]
=> 497

Which of the following ordered pairs is not a solution of the system of inequalities? y > x2 – 4x – 5 y < –x2 – 5x + 6 Question 62 options: A) (1, 7) B) (1, –7) C) (1, –5) D) (–1, 6)
Answer:
a) (x, y) = (1, 7)
Step-by-step explanation:
Let be the following system of inequalties:
[tex]y > x^{2}-4\cdot x -5[/tex]
[tex]y < -x^{2}-5\cdot x +6[/tex]
We can find the right option by evaluating each option in the system of inequalities:
a) (x, y) = (1, 7)
[tex]7 > 1^{2}-4\cdot (1) -5[/tex]
[tex]7 < -1^{2}-5\cdot (1) +6[/tex]
Then,
[tex]7>-8[/tex] (TRUE)
[tex]7<0[/tex] (FALSE)
(1, 7) is not a solution of the system of inequalities.
b) (x, y) = (1, -7)
[tex]-7 > 1^{2}-4\cdot (1) -5[/tex]
[tex]-7 < -1^{2}-5\cdot (1) +6[/tex]
Then,
[tex]-7 > - 8[/tex] (TRUE)
[tex]-7< 0[/tex] (TRUE)
(1, -7) is a solution of the system of inequalities.
c) (x, y) = (1, -5)
[tex]-5 > 1^{2}-4\cdot (1) -5[/tex]
[tex]-5 < -1^{2}-5\cdot (1) +6[/tex]
Then,
[tex]-5 > - 8[/tex] (TRUE)
[tex]-5< 0[/tex] (TRUE)
(1, -5) is a solution of the system of inequalities.
d) (x, y) = (-1, 6)
[tex]6 > (-1)^{2}-4\cdot (-1) -5[/tex]
[tex]6 <(-1)^{2}-5\cdot (-1)+6[/tex]
Then,
[tex]6>0[/tex] (TRUE)
[tex]6 < 12[/tex] (TRUE)
(-1, 6) is a solution of the system of inequalties.
Therefore, we conclude that correct answer is A.

Answer:I think it y=73
Step-by-step explanation:
Answer: It is a polynomial, and the degree is 5.
I could be wrong on this but, i'm trying
Step-by-step explanation:
Polynomials in one variable are algebraic expressions that consist of terms in the form axn a x n where n is a non-negative (i.e. positive or zero) integer and a is a real number and is called the coefficient of the term. The degree of a polynomial in one variable is the largest exponent in the polynomial. Also, all exponents have to be positive in a polynomial. Another rule of thumb is if there are any variables in the denominator of a fraction then the algebraic expression isn’t a polynomial.Note that this doesn’t mean that radicals and fractions aren’t allowed in polynomials. They just can’t involve the variables.
The degree is 5 (since the largest exponent is 5)
Examples of Non- Polynomials
Example Polynomial Explanation
5x^-2 +1 Not a polynomial because a term has a negative exponent
3x^½ +2 Not a polynomial because a term has a fraction exponent
(5x +1) ÷ (3x) Not a polynomial because of the division

5.67
is it rational
Answer:
Yes
Step-by-step explanation:
It not a continues number like 1.33333... therefore it is rational. If it went on forever it would be concidered irrational.
Answer:
Yes. 5.67 is a rational no.
Step-by-step explanation:
5.67 is a terminating & non-repeating decimal . And we know that a terminating non-repeating (or repeating i.e. the decimal would have a bar) decimal no. is a rational number.
5.67 can also be written as [tex]\frac{567}{100}[/tex] . A rational is always in the form of [tex]\frac{p}{q}[/tex] form where p & q are integers. Hence 5.67 is a rational number.

46% of 125.7 is what?
a. 1.22
b. 57.8
C. 5782.2
d. 273.3
Answer:
B. 57.8
Step-by-step explanation:
Changing 46% to a decimal it would be 0.46
125.7 * 0.46 = ?
125.7 * 0.46 = 57.822
57.822 rounds to 57.8 which is answer B.

Esme buys jacketsfor 500 each and prices them for 700 each.If the selling price is reduced by 20%. how much profitdoes Esme make on each items .
Answer:
($) 60 is the profit per item when the selling price is reduced by 20%
Step-by-step explanation: 20% of 700 is 140.
The original profit is 700 - 500 = 200. The selling price is 140 less, Subtract 140 from 200. That leaves a profit of 60. (Not necessarily dollars, as the currency was not given in the question.)

hi! when finding a ratio, like teeth to no teeth, (pretend theres 9 faces with teeth and 10 with none), do you put the bigger number in front or follow the question and put the 9 faces with teeth first?
Answer:
it matters what word came first
Step-by-step explanation:
The order of the items in a ratio is very important, and must be respected; whichever word came first in the ratio (when expressed in words), its number must come first in the ratio.
4:3. The order of numbers in a ratio is important. ...

Given that 6 x − 4 y = 29 Find x when y = 4
Answer:
[tex]x=15/2=7.5[/tex]
Step-by-step explanation:
So we have the equation:
[tex]6x-4y=29[/tex]
And we want to find x when y is 4.
So, substitute y for 4:
[tex]6x-4(4)=29[/tex]
Multiply:
[tex]6x-16=29[/tex]
Add 16 to both sides:
[tex]6x=45[/tex]
Divide both sides by 6:
[tex]x=45/6[/tex]
Reduce by dividing both layers by 3:
[tex]x=15/2=7.5[/tex]
And this is our answer :)
Answer:
[tex]7.5 \: or \:7\frac{1}{2}[/tex]
Step-by-step explanation:
[tex]6x- 4 y = 29\\x =?\\y =4[/tex]
Substitute 4 for y in the given equation ;
[tex]6x-4(4)=29\\6x -16=29[/tex]
Collect like terms
[tex]6x = 29+16[/tex]
Simplify
[tex]6x = 45[/tex]
Divide both sides of the equation by 6
[tex]\frac{6x}{6} = \frac{45}{6} \\\\x =\frac{15}{2} \:or \: 7.5 \: or \:7\frac{1}{2}[/tex]
