A family has two cars. The first car has a fuel efficiency of 20 miles per gallon of gas and the second has a fuel efficiency of 15 miles per gallon of gas. During one particular week, the two cars went a combined total of 1325 miles, for a total gas consumption of 75 gallons. How many gallons were consumed by each of
the two cars that week?

Step-by-step explanation:

Assume that the mile-per-gallon car consumed all that gallons of fuel. How far would the cars have travelled?

.

This assumption overestimated the total mileage of the two cars by . Here's why: for every gallon that the second ( mile-per-gallon) car consumed, this assumption would overestimate the total mileage by . Therefore, the overestimation of corresponds to:

.

Therefore, the second car consumed . The first car would have consumed .

da freeck kinda math is this just drop out

step-by-step explanation:

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
