Answers

5x+3y=39
x+y=3
we will eliminate the y terms first
multiply bottom equation by -3
-3x-3y=-9
add this to the first equation
5x-3x+3y-3y=39-9
2x+0=30
divide both sdies by 2
x=15

subsitute into second equation
x+y=3
15+y=3
subtract 15 from both sdies
y=-12

x=15
y=-12

Rick rents a car from a company that charges him $25 per day plus 10 cents per mile driven. Which expression can represent the amount he owed on a recent rental?a.) 25x + 0.1y
b.) 251.x
c.) 25.1xy
d.) 25.1 + 35y

Answers

Let x be the number of days and y represent miles driven.

Since it costs 25 per day, you multiply 25 by x.
25x

10 cents (otherwise known as .1 dollars) per mile, multiply .1 times y. Now add the two.
.1y

25x+.1y

The answer is a.) 25x + 0.1y.
