X=12, because when you use the constant of proportionality, which in this case is three, that’s what you multiply by 4 in the numerator side to equal 12.
C.) 2 is the right answer
Step-by-step explanation:
Given
-15(x-__)=25
We can see in the next step
![-15x+30=25](https://tex.z-dn.net/?f=-15x%2B30%3D25)
We can check by substituting each option one by one
So,
A.) -30
![-15(x-(-30))=25\\-15(x+30)=25\\-15x-150=25](https://tex.z-dn.net/?f=-15%28x-%28-30%29%29%3D25%5C%5C-15%28x%2B30%29%3D25%5C%5C-15x-150%3D25)
We can see that by putting -30 we don't get the expression given in the picture so it is not the right answer.
B.) -2
![-15(x-(-2))=25\\-15(x+2)=25\\-15x-30=25](https://tex.z-dn.net/?f=-15%28x-%28-2%29%29%3D25%5C%5C-15%28x%2B2%29%3D25%5C%5C-15x-30%3D25)
We can see that by putting -2 we don't get the expression given in the picture so it is not the right answer.
C.) 2
![-15(x-2)=25\\-15x+30=25](https://tex.z-dn.net/?f=-15%28x-2%29%3D25%5C%5C-15x%2B30%3D25)
We get the same expression by putting 2 in the blank so it is the right answer.
Hence,
C.) 2 is the right answer

Answer:
Jeffrey will be able to sing 18 pieces over 9 weeks
Step-by-step explanation:
5 9
10 x
5x = 90
x = 18
The answer is 33 because you would subtract 3 from 63 and then divide 60 by 2 which is 30. Since Mr. Smith is 3 years older then u would add 30 and 3.
The quotient is (2x²+10x-5).
<h2>Polynomial</h2>
Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.

Then the equation become
(x+1)(x+2)(x-0.5)(x0.5) then divide the polynomial by x - 3.
![\dfrac{3x^4+6x^{2} +2x^{2} +9x+10}{x+2} = \dfrac{(x+1)(x+2)(x-0.5)(x-0.5)}{x+2} \\\dfrac{3x^4+6x^{2} +2x^{2} +9x+10}{x+2} = (x+1)(x-0.5)(x-0.5)](https://tex.z-dn.net/?f=%5Cdfrac%7B3x%5E4%2B6x%5E%7B2%7D%20%2B2x%5E%7B2%7D%20%2B9x%2B10%7D%7Bx%2B2%7D%20%20%3D%20%5Cdfrac%7B%28x%2B1%29%28x%2B2%29%28x-0.5%29%28x-0.5%29%7D%7Bx%2B2%7D%20%5C%5C%5Cdfrac%7B3x%5E4%2B6x%5E%7B2%7D%20%2B2x%5E%7B2%7D%20%2B9x%2B10%7D%7Bx%2B2%7D%20%20%3D%20%28x%2B1%29%28x-0.5%29%28x-0.5%29)
And on multiplication we have,
![(x+1)(x-0.5)(x-0.5) = (3^{3} +2x+5)](https://tex.z-dn.net/?f=%28x%2B1%29%28x-0.5%29%28x-0.5%29%20%3D%20%283%5E%7B3%7D%20%2B2x%2B5%29)
Thus the quotient is
