Start with the right hand side.

1/2(3 - x)

This reads as The difference between 3 and a number. You put it the way you read it difference between 3 and a number = 3 - x The 1/2 affects both terms. So that makes b and d incorrect.

The left side is a bit harder. You want the sum of 6 + something. Read the rest of the given

6 + 2(x +4)

Now that is all equal to

6 + 2(x + 4) = 1/2 (x - x)

The answer is A

It takes an airplane 5/12 of a minute to fly 3/4 of a mile. What is the airplanes speed per minute?

Nikitich [7]

To make this a little easier, you would want to turn 3/4 into 9/12, to match 5/12's denominator.

You would then just add 7/1 to both fractions

(5/12+7/1=12/12 or 1 minutes)
(9/12+7/1=16/12=1 1/3)

So your answer would be 1.333... miles per minute

Hope this helps
