Answer:
Step-by-step explanation:
It is assumed the width of the street is the distance between the opposite buildings.
<em>See the picture attached</em>
<u>It comprises of two parts: </u>
<u>Using Pythagorean theorem, lets find the value of x:</u>
- x² + 15² = 17²
- x² = 289 - 225
- x² = 64
- x = 8 m
<u>Same rule for y:</u>
- y² + 8² = 17²
- y² = 289 - 64
- y² = 225
- y = 15 m
<u>The width of the street (road) is:</u>
Given :
Fitness center A has a $60 enrollment fee and costs $35 per month. Fitness center B has no enrollment fee and costs $45 per month.
To Find :
A) Identity the variables then write system of linear equations to represent the situation.
B) In how many months will both fitness centers cost the same? What will the cost be? Use the substitution method to solve this real-world application.
Solution :
a) Linear equation of center A :
F = 35x + 60 ...1)
Linear equation of center B :
F = 45x ...2)
b) Let, after n months both fitness centers cost the same fee :
So, 35m + 60 = 45m
10m = 60
m = 6 months
Putting value of m in equation 1) or 2) is :
F = (35×6) + 60 = $270 or F = 45×6 = $270 .
Therefore, the cost when they have same fee is $270 .
Hence, this is the required solution.
