The answer would be 119 and 4/7
Answer: 3.017hp
Step-by-step explanation: 745.7watts = 1hp
2250watts will be (2250/745.7)hp
i.e 3.017watts
it is 10% because 10 percent got better in the experiment
-3x + 5y = -9
4x + 8y = 12
Simplify the second,
x + 2y = 3
Times three,
3x + 6y = 9
Add to the first equation,
11y = 0
y = 0
-3x + 5(0) = -9
x = 3
Answer: x=3, y=0
