The speed limit is 35 mph. todd is stopped for
speeding and is fined $12 for every mile over
the speed limit. write an equation for the fine
that todd will have to pay. use fas the
variable for the fine, and s for the speed of the
car.

An equation for the fine  that Todd will have to pay  is f =  12(s -35)

Step-by-step explanation:

Given:

Speed limit = 35 mph

Fine amount for every mile over  the speed limit  =  $12

To Find:

An equation for the fine  that Todd will have to pay = ?

Solution:

The fine amount todd have to pay  =f

Speed at which todd travelled = s

Then

It is said that that the fine amount  $12 for every mile over  the speed limit

The speed beyond the speed  limit = (s -35)

Now the fine amount will be

f =  12(s -35)

f = 12s - 420

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
