On anne's bicycle, the ratio of pedal turns to rear-wheel turns in second gear is 4 to 7. if her rear wheel turns 875 times per

quester [9]

Let the number of times she turns the pedal in one mile be x.

Given that her rear miles turns 875 times in one mile and the ratio of pedal turns to rear wheel turns is 4 to 7, then

$\frac{4}{7} = \frac{x}{875} \\ \\ \Rightarrow 7x=4(875)=3,500 \\ \\ \Rightarrow x= \frac{3,500}{7} =\bold{500}$

Therefore, she turns the pedal 500 times in one mile.

Don's Car Rentals charges a flat rate of $35 per day plus $2 per mile. If the number of miles is represented by m, what is the a

Mumz [18]

Given that, Don's Car Rentals charges a flat rate of $35 per day plus $2 per mile.

The number of miles is represented by m.

For 1 mile the charge is $2. So, for m miles the charges will be 2m.

Since, Don's Car Rentals charges a flat rate of $35 per day .

So, total charge must be the sum of 35 and 2m.

Hence, the algebraic expression representing the overall rate for the day is

35 + 2m.

Hope this helps you.
