SHOW YOUR WORK!! 1. A crowd of people stood on both sides of the street to view a 4th of July
Parade. The length of the parade was 3 miles long and 5 feet deep on each side of
the street. If 8 people can fit into a 25 ft2 area.
Estimate the size of the crowd.
(1mile = 5280ft)

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

answer: 94

step-by-step explanation: 79+91+92+94+94 = 450 divided by 5 (since there are 5 number that are being added) = 90
