Solve this for the brainlist
ella [17]

Answer:

22.4

Step-by-step explanation:

using altitude theorem, the height of the triangle is 20

let y = height

10/y = y/40

y² = 400

y = \sqrt{400} or 20

Now we can us the Pythagorean Theorem to find 'x':

10² + 20² = x²

100 + 400 = x²

x=\sqrt{500} ≈ 22.4

Substitution property of equality if y=-5 and 7x+y=11, then
slamgirl [31]
X = 16/7 Because if you substitute -5 in for y you get x = 16/7 and you can check by plugging in 16/7 in for x and you get -5 for y so your answer is: x=16/7

First you need to set up your equation.

If you read the question it states one equation IS THE SAME AMOUNT of another equation so here it is:

3x+7= 2x+18

You want to find out x in both equations so I’ll help step by step

1. Subtract 2x from both sides

This leaves you with x+7=18

2. Then subtract 7 on both sides

This leaves you with x=11

So x equals 11 for equations.

You can check by plugging in 11 in x. If you get 40 on both sides....

CONGRATS!! You did it

I hope this helped. Have a great day!
