Erin washed the car 4 minutes slower than half of the amount of time it took time it took
Tad to mow the lawn. In total, the two jobs took Erin and Tad 62 minutes. The amount of
minutes that the jobs took Erin (x) and Tad (y) are given with the system of equations.
X=1/2y-4 x+y=62 How many minutes did it take Erin to wash the car?

The answer is 27. you just have to understand it lol!

Good luck! Happy new year!

Step-by-step explanation:

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!
