➷ 847) You need to cross multiply
Multiply both sides by (x - 7) and 3
This is what you should get:

Now we just need to get like terms on the same side.
Add 42 to both sides and subtract 2x from both also
Now you get this:

848) It's the same principle in this one too.
Multiply both sides by (x - 13) and 11
You should get:

Subtract 11x from both sides and add 156 also
Now you get:

849) Multiply both sides by x
You should get:

Add 4x to both sides and add 12 also:

Divide both sides by 5

850) Multiply both sides by x
You should get:

Subtract x from both sides:

Divide both sides by 3:

Answer:
The total distance Allie traveled was 0.81 miles.
Step-by-step explanation:
Since Allie rode her bike up a hill at an average speed of 12 feet / second, and she then rode back down the hill at an average speed of 60 feet / second, and the entire trip took her 2 minutes, to determine what is the total distance she traveled, the following calculation must be performed:
12 + 60 = 72
72 x 60 = 4320
1000 feet = 0.189394 miles
4320 feet = 0.8181818 miles
Therefore, the total distance Allie traveled was 0.81 miles.
