Hi.
To find the unit rate we just need to divide the total cars washed in 5 hours (20) by the hours (5)
20 / 5 = 4
The unit rate is 4 cars/hour.

The two numbers are 17 and 9
x+(x+8)=26
x=9
x+8(second number)=17
Hope this helps.
Have a nice day.
Answer:
exact form is 161/12 or 13.416
Step-by-step explanation:
3(x-7) = 138 + 3x First multiply
3x-21 = 138 + 3x subtract 3x from both sides
-21 = 138
This is a false statement because -21 does not equal to 138 so the answer is no solution.
