Answer:
54 minutes
Step-by-step explanation:
We can write a proportion to solve this problem. Put the number of pages over the minutes
27 pages 324 pages
-------------- = ---------------
4.5 minutes x minutes
Using cross products
27 * x = 324 * 4.5
27x = 1458
Divide each side by 27
27x/27 = 1458/27
x =54
Answer:
x =144
Step-by-step explanation:
A straight line is 180 degrees
x+ x/4 = 180
Change 1 to 4/4 to get a common denominator
4/4x +x/4 = 180
Combine like terms
5/4x = 180
Multiply by 4/5 on each side to isolate x
4/5 * 5/4 =180 * 4/5
x =144
