X=7. The two segments on the bottom as well as on the diagonal are the same length. This shows that the entire triangle and the inner triangle on the right are similar. So if we call the length of the bottom 2y, then 84/2y=6x/y. Solving this we get 84=12x, and so x=7

The cost to rent a car is $25 plus an additional $0.15 for each mile the car is driven. Which of the following equations could b
kirill [66]

Answer:

25 + 0.15m = 71.8

Step-by-step explanation:

Given:

Fixed charge = $25

Additional charge for each mile = $0.15

Let number of miles driven be m.

Total Billed amount = $71.80

Now total bill amount is calculated by adding fixed charge with additional charge for each mile times number of miles.

Hence,

Total Billed amount  = Fixed charge + Additional charge for each mile × number of miles driven

25 + 0.15m = 71.8

Hence the equation is 25 + 0.15m = 71.8.
