Answer: 591
Step-by-step explanation:
12 x 13= 156
12 x 5= 60 x 2= 120
12 x 5= 60/2= 30 x2= 60
5 x 12= 60
13 x 15= 195
195 + 60 + 60 + 120 + 156= 591
Answer:
x/3.5h = -$1.4
So, x = -$1.4 * 3.5h
= -$4.9
Step-by-step explanation:
Since your losing $1.4 every hour, the 1.4 is supposed to negative.
Also, since your losing that amount of money for 3.5 hours, we are trying to find the total of how much money is lost in the 3.5 hours. To do this, we have to do x/3.5h = -$1.4. But since you can't do x/3.5, we have to do inverse operation. When you divide 3.5 hours to the other side of the equation it becomes multiplication. So you do -$1.4 times 3.5 hours
and get -$4.9.
