Answer:

B) 3 7/9 or 34/9

Step-by-step explanation:

I believe that x is what you need to multiply 2 1/4 by in order to get 8 1/2.

Can you break down how this equation was solved?

dolphi86 [110]

Yes! Let me help you!

Here is the original equation, lets solve this step-by-step

(x + 2)/4 = 5

Now, lets find out how.

We must apply the inverse operation.

4/2 is the reciprocal, so lets multiply that to both sides.

4/2 = 2
5*4 = 20

4x + 8 = 20
-8 -8 Subtract 8 from both sides. (Inverse operation)

4x = 12
4x/4 = 12/4 Divide 4 by both sides (Inverse)

x = 12/4
x = 3 Simplified

Answer: x = 3
