A. x-6=6
if u plug in 12, you get 12-6=6 which is true
all the other ones would be false if you plugged in 12
X = 40, Y = 15
40(2) + 15(2) = 80 + 30 = 110 :)
8(t+2)-3(t-4) = 6(t-7)+8
8t+16-3t+12=6t-42+8
5t+28=6t-34
t = 62
Answer:
a = 11
Step-by-step explanation:
One is given the following equation:
3a - 7 = 26
Use inverse operations to solve this equation:
3a - 7 = 26
(add (7) to both sides)
3a = 26 + 7
Simplify,
3a = 26 + 7
3a = 33
Inverse operations,
3a = 33
(divide both sides by (3))
a = 33 / 3
Simplify,
a = 11
The longer side is 36 and the shorter side is 24
