Answer:
x = - 2
Step-by-step explanation:
Given
- 1.2x + 2.5 = 0.8x + 6.5 ( subtract 0.8x from both sides )
- 2x + 2.5 = 6.5 ( subtract 2.5 from both sides )
- 2x = 4 ( divide both sides by - 2 )
x = - 2
(5x-2) + (2x+6) = 67, so we simplify and solve for x:
7x + 4 = 67 --> 7x = 63 --> x = 9
Now we substitute 9 for x in (5x-2):
5(9) - 2 --> 45 - 2 = 43
The distance between A and B is 43 miles.

Determine the inequality
First, we need to determine the total cost for x miles.
The total cost can not exceed the amount he has, so the inequality is:
Answer:
a
Step-by-step explanation:
There's only one solution...the one you get when you divide both sides by 22 to solve for x. 902/22 = 41. That exponent on the x, the one you don't see, is a "1" which tells us that there is only 1 solution to this problem. If your x is squared, then you have 2 solutions; if it's cubed, you have 3, etc.
