The answer is 275. hope it helps :)
Here, I'll do the first one for you.
When they are talking about a number, use "x".
Since it says twice a number, you say 2x. Or 3x for three times the number
2x+12=3x-31
Then use algebra to find x. Get the numbers on one side and all the x's on the other.
2x+12+31=3x-31+31
2x+43-2x=3x-2x
x=43
Now do the rest on your own!

Answer:
9.6 kW
Step-by-step explanation:
The product of volts and amps is watts. Here, that product is ...
(240 V)(40 A) = 9600 W
1000 W is 1 kW, so this quantity is 9.6 kW

This tells the power consumption. The "rating" may be different.
Answer is B (hope this helps!)
Take it like this
27% of x = 162
27/100 * x = 162
x = 162*100/27
x=600
Therefore, 27% of 600 is 162
