Let r = rental, g = gas, m = miles
r1 + g1 + 0.25m = r2 + g2 + 0.35m now plug in and solve for m
40 + 15 + 0.25m = 45 + 0.35m
55 - 45 = 0.35m - 0.25m
10 = 0.1m
100 = m
 for 100 miles the cost will be the same
now to find the cost
0.25m plug in 100 for m
0.25(100) = 80
for the course of 100 miles the cost will be $80

What is value of x?<br><br><br><br> Enter your answer in the box.<br> x =
Ghella [55]

The bisector divides the line BC in the following ratio.

(x + 8) / 10 = (2x - 5) / 14      Cross Multiply

14(x + 8) = 10(2x - 5)            Remove the brackets.

14x + 112 = 20x  - 50           Subtract 14x from both sides . Add                                                                                                                             50 to both sides

112 + 50 = 20x - 14x             Collect like terms

162 = 6x                               Divide by 6  

x = 27
