5x-9y=-65
10x-3y=20
Multiple the first equation by 2
10x-18y=-130
10x -3y=20
Then subtract the two equations to get rid of the x
21y=-150
Divide the -150 by 21
Y=-7.14
Plug the y into the original equation. (Either one)
5x-9(-7.14)=-65
5x-64.28=-65
Then add 64.28 to the -65
5x=-0.72
Divide by 5
X=-0.144
I hope this is right
Answer:
Step-by-step explanation:
First, you would multiply 3x4 =12
next you would keep the denominator the same
last you would divide 8 by 12 10 get 1 3/8 for your answer
x is the middle line because it divides each catheter into two equal parts.
==> x is half the hypotenuse.
Answer:
900mph
Step-by-step explanation:
because i calculated
45-5 =40
40/2 = 20
20+5 = 25
the 2 numbers are 20 and 25
