Answer:
0.25x -12= 18- 0.55x (subtract 0.25x from both sides)
-12= 18 -0.80x (subtract 18 from both sides)
-30= -0.80x (divide each side by -0.80)
x= 37.5 (this is your answer)
An octagon has eight sides
Answer:
5.2
Step-by-step explanation:

To solve for x, we want to isolate x. To do this, we need to multiply both sides by 4.

Multiply the numerators and the denominators separately.
4 • 17 = 68
1 • 13 = 13

Divide.
68 ÷ 13 = 5.23
Round to the nearest tenth.

Hope this helps!
Answer:
4
Step-by-step explanation:
First, use the distributive property: 2x+16=4x+8
Second, move +8 to the other side(and turn it negative): 2x+8= 4x
Do the same for +2x: 8=2x
divide both sides by 2: 4=x
