Answer:
x = 6
Step-by-step explanation:
First, simplify both sides:
6 - 3x = -5x + 18
Move like terms to one side. Note that when you move a term from one side to another, the sign is changed (+ --> -)
6 - 18 = -5x + 3x
-12 = -2x
x = 6
perimeter = sum of all sides
27 = 9+7.8+x
x (third side) = 10.2
Answer:
9.6
Step-by-step explanation:
It's rational as it has a finite number of digits, can also be represented as 96/100
$5 per hour because it can change. A one time thing like b,c,d is not a variable amount because its just a one time thing. So the answer is A $5 per hour
