10 People fit comfortably in a 5 feet by 5 feet area. Use this value to estimate the size of a crowd that is 5 feet deep on both sides of the street along a 2-mile section of a parade route.

The size of the crowd that is 5 feet deep on both sides of the street along a 2-mile section of a parade route is 42,240 people

Step-by-step explanation:

The number of people that can fit comfortably in a 5 feet by 5 feet area = 10

Therefore;

The ratio of the number of people per unit area = 10/(5 × 5) = 10/25

The area, A, occupied by the crowd = 5 feet × 2 mile × 2

2 miles = 10,560 feet

∴ A = 5 feet × 10,560 feet × 2 = 105,600 ft²

We then have;

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8
