Can someone help? ASAP!? (16 pts)

Answer 1

D in (-00+00)
(3/8)*d-(3/4)=0
(3/8)*d-3/4=0
3/8*d-3/4=0 // + 3/4
3/8*d= 3/4 // : 3/8
d = 3/4/3/4
d=2
d=2

Answer 2

The coefficient of the variable is 3/8.

$\sf\dfrac{3}{8}(?+?)$

Divide 3/8 to each term to find out what goes in the parenthesis:

$\sf\dfrac{3}{8}b\div\dfrac{3}{8}=b$

So 'b' goes into the first spot in the parenthesis:

$\sf\dfrac{3}{8}(b+?)$

$\sf\dfrac{3}{4}\div\dfrac{3}{8}$

When dividing by fractions we flip(reciprocal) the one we're dividing by and multiply:

$\sf\dfrac{3}{4}\times\dfrac{8}{3}$

Multiply:

$\sf\dfrac{24}{12}$

Divide:

$\sf 2$

This goes into the second spot in our parenthesis.

$\boxed{\sf\dfrac{3}{8}(b+2)}$
