The hot tub takes in 1,520 watts everyday to keep its water warm. A kilowatt has 1,000 watts (hence kilo means 1,000). 1,520 divided by 1,000 equals 1.520. However, this isn't free electricity - Each kilowatt costs 8 cents or 0.08 of a dollar. 1.520 x 0.08 = 12.160 or $12.16. We aren't done yet! This hot tub runs for 4 months (and we are assuming these months exactly have 30 days each). 4 x 30 = 120. $12.16 x 120 = $1,459.20. In order to keep the hot tub running, you need to pay 1,459.20 for all the kilowatts of electricity it takes.
Answer:
x = 5
y = 6
Step-by-step explanation:
-3x + 2y = -3
-x - y = -11 (Multiply everything by 2)
-3x + 2y = -3
-2x - 2y = -22
-5x = -25
x = 5
-x - y = -11
-5 - y = -11
-y = -11 + 5
-y = -6
y = 6
