you want to get an oil change every 4,000 miles. how many oil changes do you get in a year driving 1000 miles a month?

a year has 12 months, driving 1000 miles a month and changing the oil every 4000 miles

let 'x' represent the number of oil changes in one year:

x=(12*1000)/4000

x=3

So 3 oil changes would be obtained throughout the year. 

28

step-by-step explanation:

8+8+6+6

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
