Answer:
3 oil changes
Step-by-step explanation:
1. Find an equation that represents this word problem: 3000x + 5000 = y
Where y = the # of miles total. y = 250 miles/week * 52 weeks/year = 13000 miles.
2. Solve for x: 3000x + 5000 = 13000 3000x=8000
3. x = 8/3 integer round down x = 2 oil changes, but plus the one after 5000 miles is a total of 3 oil changes that year
4x^7
——-
8y^6
this is the simplified answer. you flip negative powers.
Since they are different people with different thoughts and knowledge giving them to choose different numbers all though two of them might choose the same number
1. multiply both sides by 16
a. 8n-2n=6
b. Subtract the like terms on the left
6n=6
c. Divide both sides by 6
d. the answer is n=1
