<h3>
x = 2</h3><h3 />
Step-by-step explanation:
use Pythagorean theorem:
a² + b² = c²
where a = x
b = 8/2 = 4
c = √20
plugin values into the formula:
x² + 4² = (√20)²
x² + 16 = 20
x² = 20 - 16
x = √4
x = 2

Answer:
The total cost for each health club will be the same after 4 months.
Step-by-step explanation:
- Let A = membership fee for studio A
- B = membership fee for studio B
We want to when the total cost at each health studio is the same.
In other words, when A = B.
Therefore, the expression becomes


Step 1: Simplify both sides of the equation.

Step 2: Subtract 18.25x from both sides.


Step 3: Subtract 22 from both sides.


Step 4: Divide both sides by 6.25


Therefore, the total cost for each health club will be the same after 4 months.
Answer:
200 + 50x = 450
Step-by-step explanation:
So, 200 + 50x = 450
50x = 450-200 = 250
X = 250/50
X = 5
Check:
200 + 50(5)
= 200 + 250 = 450.
