What is the simplified expression for the expression below? -1/5(5x+20)-1/4(4x-28)
e-lub [12.9K]

You need to distribute the numerical factors for each term in the parenthesis:

\dfrac{-1}{5}(5x+20)-\dfrac{1}{4}(4x-28) = \dfrac{-1}{5}\cdot 5x + \dfrac{-1}{5}\cdot 20 + \dfrac{-1}{4} \cdot 4x + \dfrac{-1}{4} \cdot (-28)

This equals

-x-4-x+7 = -2x+3

If (a, –5) is a solution to the equation 3a = –2b – 7, what is a?
sukhopar [10]

Answer:

d)  1

Step-by-step explanation:

3a = –2b – 7

We have the point (a, -5) so b = -5

Substituting in

3a = -2(-5) -7

3a = 10-7

3a = 3

Divide each side by 3

3a/3 = 3/3

a =1
