Calculate for 3 days: 2,400 x 3 = 7,200
Calculate 1 day per hour: 2,400 ÷ 24 = 100
Calculate for 6 hours: 100 x 6 = 600
7,200 + 600 = 7,800 watt-hours
Answer:
(-1,7)
Step-by-step explanation:
-9x + 2y = 23
-4x - y = -3
multiplying equation 2 by 2
-9x + 2y = 23
-8x - 2y = -6
adding the two equation to cancel out y
-17x = 17
x = -1
plugging back x = -1 into the second equation
4 - y = -3
-y = -7
y = 7
