The correct answer would be b.25
In 1980, wind turbines in Europe generated about 5 gigawatt-hours of energy. Over the next 15 years, the amount of energy increased about 59% (each year). How many gigawatt-hours were generated
For this case we have the following equations:
y = 60x + 40
y = 50x + 80
Equaling both equations we have:
60x + 40 = 50x + 80
From here, we clear the value of x:
60x - 50x = 80 - 40
10x = 40
x = 40/10
x = 4 weeks
Substituting x = 4 in any of the equations we have:
y = 60 (4) + 40
y = 240 + 40
y = 280 $
Answer:
$ 280 4 weeks
Answer:
20 months approx
Step-by-step explanation:
Given data
Price=$2,350
Monthly savings= $115 per month
Hence the duration of time to save up $2,350 is given as
=2,350/115
=20.434
Hence the time is 20 months approx
3xy -6x
just multiply 3x by y and 3x by -2
