2/x-9. You must divide 2 by x first to follow the order of operations then subtract by nine.
Well one similarity is that since you have to multiply, integer rules still apply and that you can also multiply variables. A difference is that with fractions, you have to make a number into an improper fraction rather than just the regular way which would most likely be the whole number with a decimal.
The number is 12.
7 + 5 = 12
12 • 3 = 36
Hope I helped!
Distance = speed x time
time = distance/speed
= 340/85
= 4h
