The cost of renting a car is $35/wk plus $0.2/mi traveled during that week. an equation to represent the cost would be y=35+0.25x, where x is the number of miles traveled. If your cost was $48.75, how many miles were you charged for traveling?

69 miles approx.

Step-by-step explanation:

Cost(x) = y = $35 + 0.2x = $48.75

Note that each mile costs $0.20, not $0.25.

Subtracting $35 from both sides, we get:

0.2x = $13.75, which works out to x = 68.75.

You were charged for 69 miles of travel.

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
