Marie started the week with an odometer reading of 68,240 miles and a full tank. She ended the week with a reading of 68,615 and filled the tank with 15 gallons of gas. What is her mpg to the nearest whole number?

22

23

24

25

25

Step-by-step explanation:

Difference in miles = difference in odometer reading

d = 68,615 - 68,240 =  375 miles

So, if she used 375 miles by the end of the week, then her mile per gallon will be calculated with this equation below:

375 / 15 = 25

Therefore, the correct answer is 25.

tickets for the harlem globetrotters

show at michigan state university in

2010 cost $16, $23, or, for vip seats, $40.

total revenue = 16x + 23y + 40z

if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, sales of all three kinds of tickets would

total $46,575.

16x + 23y + 40z = 46575, how many of each kind of ticket would

have been sold?

solve for x, y and z

x − 9z = 0

x − y − z = 55

16x + 23y + 40z = 46575

x = 1170

y = 985

z = 130

welcome!

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
