Last month, my house used 1,740 kilowatt-hours of electrical energy,
and the part of my bill that charged for the electricity was $226.20 .
For the same month, my brother in Boston used 1,175 kilowatt-hours
of energy, and the energy part of HIS bill was $199.75 .
Which of us gets the better deal on his electrical energy ?
A) 4 (3x+2)-2
12x+8-2
12x+6
2x+1 simplified expression
I think the answer is x=2 <span />
The probability of getting a two is 2/12.
81^1/3. We know that 81 is 3^4, meaning 3 x 3 x 3 x 3 is 81. So (3^4)^1/3 is 3^4/3, which is 3 * (cubed root of 3).
