Grace weighed 167 pounds before she started her exercise program.

Step-by-step explanation:

Given,

Weight lost by Grace = 45 pounds

Weight of Grace after exercise weeks = 122 pounds

Let,

x represents the weight of Grace before she started the exercise program.

Loss means subtraction, therefore,

We will subtract the lost weight from original weight.

Original weight - Weight lost = Weight after exercise weeks

x-45=122

Adding 45 on both sides

x-45+45=122+45\\x=167\ pounds

Grace weighed 167 pounds before she started her exercise program.

Zahir completes 1/5 of his homework in 5/15 of an hour. How much time will
kogti [31]

Answer:

t = 100 minutes, or 1 hr, 40 minutes

Step-by-step explanation:

5/15 of 1 hour is the same as 5/15 of 60 minutes, which is 20 minutes

you can set up a proportion of hw completed / minutes = hw completed / min:

(1/5 ÷ 20) = (1 ÷ t)    we use '1' to indicate all homework (or 100% of hw) and 't' to indicate time required

cross-multiply to get:

20 = 5/t

t = 100 minutes, or 1 hr, 40 minutes
