Answer:
64
Step-by-step explanation:
You'd put 64 in the box because the x is the original number (4). example: 4^3 = 64, ^3(insert the root sign) 64 = 4
sorry in advanced, I dont have the math signs to make the equations
8x > = -64
x > = -64/8
x > = -8
10x < 60
x < 60/10
x < 6
-8 < = x < 6
You're on the right track. If they generated 380 less than 2012, then in 2013 they generated 9782-380 = 9402.
They used 10472 in 2012, so 10472+390 = 10862 used in 2013. now subtract used from produced to see how much they had to buy...
10862-10472 = 390
They had to buy 390khW from the power company.
It would be 29 because 8hours - 45minutes =7hours 15 minutes
7hours 15minutes divided by 15 minutes =29
