Which expression represents the calculation “subtract 4 from 12, then divided by 8”? a) 4 ÷ (12 − 8) b) (12 − 4) ÷ 8 c) (4 − 12) ÷ 8 d) 8 − (12 ÷ 4)

The answer is B

As the question states that you need to "subtract 4 from 12" that means that you are taking 4 away from 12, so it would be 12-4.

Then it says to divide by 8. This means that for the subtraction to happen first, it must be withing parenthesis, so that would make the expression become

(12-4)÷8

24 inches

Step-by-step explanation:

Set up the equation like this

3 inches is to 1.25 miles as x inches is to 10 miles

3/1.25 = x/1,0  solve x by using cross multiplication

30 = 1.25x

30/1.25 = x

24 = x
