Answer:
Subtract 6.4 from each side of the equation
Step-by-step explanation:
The equation;
3.5 n + 6.4 = 42.5
The first step is ; Subtract 6.4 from each side of the equation
We get ;
3.5 n = 36.1
Second step; we divide each side by 3.5
we get;
n = 10.31
Answer:
The correct answer is option 2
Subtract 6.4 from the each side of equation
Step-by-step explanation:
The given equation,
3.5n + 6.4 = 42.5
To solve the equation
3.5n + 6.4 = 42.5
Step 1: Subtract 6.4 from the both side
3.5n + 6.4 - 6.4 = 42.5 - 6.4
3.5n = 36.1
Step 2: Divide both side by 3.5
3.5n/3.5 = 36.1/3.5
n = 10.34
Therefore the correct answer is option 2

First need to make an equation for each
x = Miles
y = Total Cost
Comp A: 120 + 0.20x = y
Comp B: 40 + 0.60x = y
cancel out the amounts to make it easier (Subtract 40 from each)
Comp A: 80 + 0.20x = y
Comp B: 0.60x = y
insert a problem for y to solve for x
80 + 0.20x = 0.60x
Your answer is 200 miles
