Answer:
A= 3
Step-by-step explanation:
4a - 7 = 5
move the constant to the right
4a= 5+7
divide
4a=12
Awnser:
A= 3
Step-by-step explanation:
y=x(x+3)-1(x+3)
y= x^2+3x-x-3
y=x^2+2x-3
that is the answer
You choose a tree and have anotherbpeeson choose a tree. You then both take the numbers on your trees and add them together. Then you check if you got the same answers. You keep on doing this until you do all the trees I think.
1.-8, 2.21, 3.27, 4.-29, 5. -18, 6. 19, 7.-14.5, 8.0.5, 9.-3.8
Step-by-step explanation:
1) x - 5 = - 2
x = - 2 + 5
x = 3
2) - 6 + x = - 9
x = - 9 + 6
x = - 3.
3) x/4 = 6/8
Cross multiply
8x = 24
x = 24/8 = 3
4) - 14x = - 42
x = - 42/-14
x = 3
5) - 3/5 + x = 12/5
x = 12/5 + 3/5
x = 15/5 = 3
6) x/3 = 9
x / 3 - 9
x - 3
x = 3
