Answer:
28 - 3h
Step-by-step explanation:
We must do the work seen inside parentheses first.
Thus, we havve 4(7) - 3h, which simplifies to
28 - 3h
-18-6k= 1+3k
9k=-19
k=-19/9
k=-2 and 1/9
A reasonable number between 18 and 23 is 20. 69 minutes is 3 times 23 minutes, so we multiply the 20 by 3, getting an estimate of 60 cars.
The answer is 5x because when you do the math 12 subtracted by 7 equals 5 then you add the x at the end.
