Question

Which shows the correct way to substitute f=72 into the equation f/6 = 12?

A. (72) f/6 = 12 (72)
B. (-72/6 = 12
C. 72f/6 = 12
D. (72)/6 = 12

Answer 1

Answer: D. 72/6

Step-by-step explanation: To substitute f = 72 into the equation f/6 = 12, we need to replace every occurrence of f in the equation with the value 72. The correct way to do this is:

72/6 = 12

Here, we have replaced f with 72 on the left-hand side of the equation, and simplified the expression by dividing 72 by 6, which gives us 12. This equation is now true when f = 72.
