(1073 + 1108 + x) / 3 = 1000
(2181 + x) / 3 = 1000 ....multiply both sides by 3
2181 + x = 1000 * 3
2181 + x = 3000
x = 3000 - 2181
x = 819 <== they would need to earn $ 819 on Sunday
Answer:
18
Step-by-step explanation:
Answer:
6
Step-by-step explanation:
f(6) is the y-value when x = 6
From inspection of the graph, f(6) = -6
g(5) is the y-value when x = 5
From inspection of the graph, g(5) = -5
Substitute the found values into the given equation:
4 · f(6) - 6 · g(5)
= 4 · (-6) - 6 · (-5)
= -24 - (-30)
= -24 + 30
= 6
Answer:
18900 watt-hours
Step-by-step explanation:
3600 x 24 (hours in a day) = 150
150 x 6 (hours) = 900
3600 (watt hours per day) x 5 (days) = 18000
18000 x 900 = 18900
total= 18900
