Milo must put 50 feet of fencing around his rectangular garden.

The length of the garden is one foot longer than twice the width.

What is the solution set for 2w + 2(2w + 1) = 50 given the replacement set {6, 7, 8, 9}?

Milo must put 50 feet of fencing around his rectangular garden. The length of the garden is one foot longer than twice the width. Find the solution set for 2w + 2(2w + 1) = 50 given the replacement set {6, 7, 8, 9} to determine the width of the garden. 

2(2w + 1) + 2w = 50 

4w + 2 + 2w = 50 

6w + 2 = 50 

6w = 50 - 2 

6w = 48 

w = 48/6 

w = 8

Cara drives for 4 hours at a rate of 45 miles per hour. Later, she drives for another 3 hours so that her total distance traveled for the day is 336 miles. Find the solution set for 4(45) + 3r = 336 given the replacement set {52, 53, 54, 55} to determine the rate at which Cara traveled during the second part of her trip. 

4(45) + 3r = 336 

180 + 3r = 336 

3r = 336 - 180 

3r = 156 

r = 156/3 

r = 52 

r = 52
