Whether you have to combine the two numbers together will be decided by you.
16’s reciprocal would be 0.0625
1/3’s reciprocal would be -3
Hope this helps and hope I am doing this right.
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:
12
Step-by-step explanation:
Im going to divide this up to make it easier
first im going to do the triangle on top which we need the formula for that which would be
(4*2) / 2 which is( base * height )/2 then 4*2 = 8 /2 = 4
then ill deal with the rectangle just below that triangle
which is 3*2 which is 6
then last is triangle which is 2*2 which is 4 / 2 so 2
then add all together
4 + 6 + 2 = 12
