Answer:
-1<x<7
Step-by-step explanation:
We need to solve each inequality and then from the interval of numbers they both have in common (doing this because of the 'and').
x-2<5
Add 2 on both sides:
x<5+2
Simplify:
x<7
These are values of x that are less than 7.
x+7>6
Subtract 7 on both sides:
x>6-7
Simplify:
x>-1
These are values of x greater than -1.
So the values they have in common are the numbers in between -1 and 7.
That is x<7 and x>-1.
You can also write it as -1<x<7.
Maybe you need a graph to convince you more.

Step-by-step explanation:
Answer:
The number of miles at which a car rented from either company cost the same amount is <u>50 miles</u>.
Step-by-step explanation:
Let x represents the number of miles at which a car rented from either company cost the same amount. Therefore, we can have the following equation:
RC = 25 + 0.14x ....................... (1)
BC = 23 + 0.18x ...................... (2)
Where;
RC = Total cost of Rent-Me Rent-A-Car
BC = Total cost of Better Deal Rental Car
The the cost of the two companies equal where RC = BC. Therefore, we equate equations (1) and (2) and solve for x as follows:
25 + 0.14x = 23 + 0.18x
25 - 23 = 0.18x - 0.14x
2 = 0.04x
x = 2 / 0.04
x = 50
Therefore, the number of miles at which a car rented from either company cost the same amount is <u>50 miles</u>.
<u>Note:</u>
This can be confirmed for equations (1) and (2) individually by substituting for x = 50 as follows:
For equation (1):
RC = 25 + 0.14(50)
RC = 25 + 7
RC = 32
For equation (2):
BC = 23 + 0.18(50)
BC = 23 + 9
BC = 32
Therefore, RC = BC = 32 confirms the answer.
