19: He multiplied instead of dividing which will make a totally incorrect answer
9x - 37 = - 118
add 37 to both sides
9x - 37 + 37 = -118 + 37
simplify
9x = -81
divide both sides by 9
9x/9 = -81/9
simplify
x = - 9
answer
x = -9
Answer:
200 miles
Step-by-step explanation:
Set up a cost equation for each plan using x for miles.
Set the equations equal.
Solve for x, the miles.
For a 1 day rental.
Plan A:
C = 0.18x + 30
Plan B:
C = 66
0.18x + 30 = 66
0.18x = 36
x = 36/0.18
x = 200
Answer: 200 miles
Since it would be 60% of the original price which is 500 it would have be $300
Answer:
-13734
Step-by-step explanation:
We're going to use pemdas for this equation.
Since there are no parenthesis we move on to exponents, which we do have, so we would cube 24, which gets us 13,824.
Next we subtract 90 from 13,824 which gives us our answer of -13,734
