Answer:
the 2x and 1/2x are the slope.(rise over run)
the +2 and -1 are intercepts on the y axis
Step-by-step explanation:
A football field is 120 yards long (100 yards playing field plus 2 end zones 10 yards each) by 53 1/3 yards wide.
1 yard = 3 feet.
120 yards x 3 feet per yard = 360 feet
53 1/3 yards x 3 = 160 feet.
The area of the football fields is 360 x 160 = 57,600 square feet.
1 bag covers 2000 square feet:
57,600 / 2,000 = 28.8 bags, round up to 29 bags are needed.
1 bag cost $27.79.
29 bags x $27.79 = $805.91 total cost.
It's 35<21-n because 35 is less that 21 and an unknown number
I believe that Charlotte bikes 499.2 meters and Mary biked 123.6 meters, so Charlotte would’ve biked 375.6 more meters.
