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.

A car and a bus set out at 2 p.M. From the same point, headed in the same direction. The speed of the car is 30mph slower than t
Blizzard [7]

Answer:

Car = 10 miles/hour

Bus = 20 miles/hour

Step-by-step explanation:

Here,

Let, the value of the speed of the bus = X

the value of the speed of the car = 2X - 30 (As the speed of the car is 30mph slower than twice)

According to the question,

2X - 20 = 2*(2x-30)

or, 2X - 20 = 4X-60

or, 2X = 40

x = 20

Therefore, the speed of the bus, x = 20 miles/hour

So, the speed of the car is (2*20-30) mph = (40 - 30) mph = 10 miles/hour.
