A right triangle is formed with the equation a^2 + b^2 = c^2
For example 7, 24, 25 is a right triangle
7^2 + 24^2 = 25^2
49 + 576 = 625
625 = 625
For example 20, 25, 30 is NOT a right triangle
20^2 + 25^2 = 30^2
400 + 625 = 900
1025 does not equal 900
Answer:
if it can't fit more than 10, would it be 9 8 7 6 5 4 3 2 1?
Step-by-step explanation:
Answer:
10%
Step-by-step explanation:
40+5+5=50
50-5=45
45*2=90
50*2=100
100-90=10
Answer:
Choose the first one and second and the last one.
Step-by-step explanation:
This is an simple
Since one equation has a negative y and the other has a positive y, I'm going to use those since they cancel each other out. Before that, the two y's need to be equal to each other.
x+2y=6
x-y=3
Multiply the bottom equation by two so then you have:
x+2y=6
2x-2y=6
The y's now cancel out:
x=6
2x=6
Add them together
3x=12
Divide
x=4.
To find y, plug x into either equation (*don't have to do both, but I will)
(4)+2y=6
(4)-y=3
Subtract four
2y=2
-y=-1
Divide each
2y/2 = 2/2
y=1
-y/-1 = -1/-1
y=1
The answer is:
x=4
y=1
I hope that helps!
