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
You would start with the equation:Let m=number of miles
49.98+0.12m=35.98+0.17m
Then solve for m
You would then get
49.98+0.12m=35.98+0.17m
-0.12m -0.12m
49.98=35.98+0.05m
-35.98 -35.98
14 = 0.05m
---- --------
0.05 0.05
280=m
Answer:
x = -11
Step-by-step explanation:
Sum= addition
times= multiplication
at least= ≥
"At least" means the left side of the equation cannot be any less than 11. The left side will be at least/at minimum 11.
2x + 1 ≥ 11
subtract 1 from both sides
2x ≥ 10
divide both sides by 2
x ≥ 5
ANSWER: x ≥ 5; x is greater than or equal to (or "at least") 5
Hope this helps! :)
