Pierre runs the same around a track each day 4 days a week. He runs a total of 12 miles each week. It takes 8 laps of the track to equal a mile. Which equation could you use to find how many laps Pierre runs each day?

Step-by-step explanation:

Let l represent number of miles ran by Pierre each day.

We have been given that Pierre runs the same around a track each day 4 days a week. So number of laps ran is 4 days would be .

We are also told that he runs a total of 12 miles each week and it takes 8 laps of the track to equal a mile. So number of laps in 12 miles would be 8 times 12.

Now, we will equate total laps ran in 4 days by 8 times 12 as:

Therefore, we can use the equation  to find how many laps Pierre runs each day.

Let us solve for l as:

Therefore, Pierre runs 24 laps each day.

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
