Greg is at his house. He gets in the car and drives north 7.4 miles and stops at the store. Then he drives 5.7 miles south to his friend's house. How far is the friend's house from Greg's house? Group of answer choices

2.7 miles

1.7 miles

13.1 miles

42.18 miles

Given:

Greg drives north 7.4 miles and stops at the store.

Then he drives 5.7 miles south to his friend's house.

To find:

The shortest distance between Greg's house and his friend's house.

Solution:

Greg drives north 7.4 miles.

He drives 5.7 miles south.

The shortest distance between Greg's house and his friend's house is difference between distance he drives north and distance he drives south.

Shortest distance = (7.4 - 5.7) miles

                             = 1.7 miles

The shortest distance between Greg's house and his friend's house is 1.7 miles.

Therefore, the correct option is C.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
