Answer:

x = 101

Step-by-step explanation:

First, simplify the equation

2x + 8 + 71 - x = 180

x + 79 = 180

both side we subtract with 79 so the 79 on the left go away

x = 180 - 79

x = 101

The Pretty Pizza Company wants to open a new pizza place on either the north side of town or the south side of town. They want t
Sidana [21]

Using proportions, it is found that the Pretty Pizza Company should open a new pizza place at any of the North or the South blocks.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

The proportion of <u>pizza places per person</u> in each block of the town is given as follows:

  • North: 32/(221 x 15) = 0.0096 < 1.
  • South: 28/(22 x 150) = 0.0084 < 1.

Both proportions are less than 0.01, hence the Pretty Pizza Company should open a new pizza place at any of the North or the South blocks.
