2z−31=−9z+24
Add 9z to both sides.
2z−31+9z=−9z+24+9z
11z−31=24
Add 31 to both sides.
11z−31+31=24+31
11z=55
Divide both sides by 11.
11z/11=55/11
z=5
Step-by-step explanation:
f(x) = 3 - 4x
f(1+a)= 3-4(1+a)
=3-4+4a
=4a-1
Answer:
y= x+7
Step-by-step explanation:
plug in 0 to x and get 7 for y
First set up an equation as your approach. I will use the equation x+4x=24 because that way you are saying that something pluse itself times 4 equals 24 which is what you want.
simplify the equation
5x=24
x=24/5
So you know onw piece will be 24/5 of a foot and the ither qould be that times 4 so 96/24 of a foot. In decimals it would be 4.8 and 19.2
