[Right Triangles Only] Pythagorean Theorem: a² + b² = c²

a is a leg
b is another leg
c is the hypotenuse

Step-by-step explanation:

Step 1: Identify

Leg a = 24

Leg b = 7 in

Leg c = x

Step 2: Solve for x

Substitute in variables [Pythagorean Theorem]: 24² + 7² = x²
Evaluate exponents: 576 + 49 = x²
Add: 625 = x²
[Equality Property] Square root both sides: 25 = x
Rewrite/Rearrange: x = 25

maw [93]

x 20
------ = -------
100 125

(The percentage x saved is equal to 20 out of 120) Cross multiply:
125x = 20(100)
125x = 2000
Divide both sides by 125
x = 16%

One way to determine the slope of a line is from two points on a line.

We can use the ones already indicated on the graph, (0,4) and (3,5).

The slope is change in y divided by change in x,

$m= \dfrac{5 - 4}{3 - 0} = \dfrac 1 3$
