Amille runs every morning before school. On Monday, she ran 2.36 miles. On Tuesday, she ran 4.88 miles. On Wednesday, she ran 3.19 miles. After she ran on Thursday, her total mileage for the week was 12.81 miles. How many miles did she run on Thursday?

Distance she ran on Thursday = 2.38 miles

Step-by-step explanation:

Given, Amille ran on Monday = 2.36 miles

On Tuesday, she ran 4.88 miles.

On Wednesday, she ran 3.19 miles.

Total distance she ran till Thursday = 12.81 miles.

Now, Distance she ran on Thursday = (Total distance) - (Distance ran on Monday to Wednesday)

= 12.81-(2.36+4.88+3.19)

= 12.81-10.43

= 2.38 miles

Hence, Distance she ran on Thursday = 2.38 miles

3

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!
