X = -5.35
Sorry if I'm wrong
The amount of degrees in a polygon: 360
In a pentagon: 360 / 5 = 72
9x - 18 = 72 Add 18 to both sides
9x = 90 Divide by 9
x = 10
5/25 = x/20
To solve a proportion cross multiply:
(5 * 20) = (25 * x)
Simplify:
100 = 25x
Divide both sides by 25:
x = 100/25
x = 4
Answer:
$5.08
Step-by-step explanation:
<h2>you add up all costs, getting to $81.35 and then you multiply it by 0.0625 (6.25% divided by 100) to get <u>
$5.08</u></h2>
Answer:
25
Step-by-step explanation:
Using pythagoras theorem
we have h^2 = 7^2 + 24^2
= 49 + 576
h^2 = 625
h = squareroot of 625
h = 25
