Question

For 1-3 write an equivalent expression 1.) -3(7+5g) 2.) (x+7)+3y 3.) 2/9-1/5*x

Answer 1

Answer:

1) –(3 • 7 • 3 • 5 • g)

2) 7+x+3⋅y

3) 2/9 – x/5

Answer 2

1. -3 ( 7 + 5 g) = -21 - 15 g = -15 g - 21
2. (x + 7) + 3y = x + 3y + 7
3. $\frac{2}{9} - \frac{1}{5} x \\ = > \frac{10-9x}{45} \\ = > \frac{-9x+10}{45}$

Hope you could get an idea from here.
