70/9
Divide
9*7 = 63
70-63 = 7
7 7/9
An equivalent ratio would be 7:10 or 70:100 or 42:60 and so on...
x=9
Add 6 to both sides of the equation. x = 3 + 6
Add 3and 6.
x=9
Answer:
245 miles driven.
Step-by-step explanation:
A car rental company charges $10 a day and 17 cents per mile to rent their cars. 17 cents = 0.17 dollars
Let x be the number of miles and y be the number of days
total change =0.17x + 10y
Given total change is 61.65 and number of days = 2
plug in the values and find out the number of miles
61.65 = 0.17 x + 2(10)
61.65 = 0.17 x + 20
subtract 20 on both sides
41.65 = 0.17x
Divide by 0.17 on both sides
x = 245
245 miles driven.
