Question

What is the value of the expression (3a-b)/(6(b+a)) when a = 4 and b = -2? Show your work to support your answer.

Answer 1

Answer:

$1\frac{1}{6}$ or 1.166 Repeating

Step-by-step explanation:

This is a very simple equation!

First you write it out

$\frac{3a-b}{6(b+a)}$

Now you plug in your values.

a = 4

b= -2

So.

$\frac{3(4) - (-2)}{6(-2+4)}$

Now, follow PEMDAS

3 (4) = 12

12 - (-2) is the same as 12+2 Which equals 14

Now you have...

$\frac{14}{6(-2+4)}$

-2 + 4 = 2

6 (2) = 12

Final Fraction is

$\frac{14}{12}$

Which can be reduced to

$\frac{7}{6}$

or

1.166 (repeating)

Hope this helps!
