Answer:
a= 2b-x
Step-by-step explanation:
You have to isolate the variable by dividing each side of the factors that does not contain the variable "a".
Factors are the multiplier and the multiplicand in the mathematical operation called multiplication.

Factors of 24:
1, 2, 3, 4, 6, 8, 12, 24
Multiples of 24:
24, 48, 72, 96, 120, so on.
6 is a factor of 24.
36 is neither a factor nor a multiple of 24.
48 is a multiple of 24.
Answer:
<h2>y=60+25h+0.3r</h2>
Step-by-step explanation:
let y be the total charges
given that the hour is h
and the cost for raw material is r
therefore
1. The first hour of service call = $60
2. For each additional hour= 25h
3. 30% over the cost of the materials.= 30/100*r=0.3r
total charges
y=60+25h+0.3r
therefore the expression is
y=60+25h+0.3r
