1.5x + 7 = 20.5
First subtract 7 from both sides
1.5x = 13.5
Then divide both sides by 1.5
x = 9
Let me know in comments if you have questions
All you have to do is move -x to the right side and -12 to the left side to remove the negative sign.
-x<-12 (Original)
0<-12+x (Add x to both sides)
12<x (Add 12 to both sides)
The answer is 12<x, or you can write it as x>12.
Answer:
22
Step-by-step explanation:
Use the trapezoid area formula.
A = (b1 + b2) / 2 * h
Plug in the values.
A = 3 + 8 / 2 * 4
A = 11 / 2 * 4
A = 44/2
A = 22
