Answer:
L = 25
Step-by-step explanation:
Let's call the Length x and width x - 15 since the width is 15 less than length
Eric needs 70 of fencing in total, the perimeter of a rectangle is calculated by adding all sides
x + x + (x - 15) + (x - 15) = 70 add like terms
4x - 30 = 70 add 30 to both sides
4x = 100 divide both sides by 4
x = 25
the answer of this equation is -5
A. 53/100
B. 163/200
C. 53/10
D. 163/20
Those are the answers to the question.
Answer:
15 miles
Step-by-step explanation:
Steve runs 3.5 miles in 30 minutes (0.5 hours). So his speed is:
r = 3.5 mi / 0.5 h
r = 7 mi/h
If his rate increases to 7.5 mi/h, the distance he runs in 2 hours is:
d = 7.5 mi/h × 2 h
d = 15 mi
