In this question, a person can read 24 pages in 1/3 of an hour. Since the hour is divided into 3 parts, we must also multiply 24 by 3 to complete 1 hour. 24 pages times 3, is equal to 72 pages per hour. Therefore, the reading rate of the person mentioned in the problem is 72 pages of a book per hour.
C. Multiply both sides by 9/5.
C = 5/9(F – 32)
We want to isolate F, which means we need to get F alone.
The quantity in the parentheses is multiplied by 5/9. We need to do the opposite, or multiply by the reciprocal to isolate the parentheses
9/5 C = 9/5* 5/9(F – 32)
9/5 C = F-32
This is the first step in isolating, or solving, for F
Step 1: Simplify both sides of the equation.
n+2=−4−n
n+2=−4+−n
n+2=−n−4
Step 2: Add n to both sides.
n+2+n=−n−4+n
2n+2=−4
Step 3: Subtract 2 from both sides.
2n+2−2=−4−2
2n=−6
Step 4: Divide both sides by 2.
2n -6
--- = ---
2 2
