Answer:
2 2/3 hours
Step-by-step explanation:
Before it was 5 hours for 1 guitar, or 5 hours/guitar
Now it is 7 guitars in 3 hours or 7/3 hours/guitar
7/3 = 2 1/3
5 hours - 2 1/3 hours = 15/3 hours - 7/3 hours = 8/3 hours = 2 2/3 hours
The reduced the time it takes to build 1 guitar by 2 2/3 hours.

Step-by-step explanation:
Answer:
x = 0, x = 1
Explanation:
3x^2 - x = 2x
3x^2 -x -2x = 0
3x^2 -3x = 0
3x(x-1) = 0
x = 0, x = 1
Answer:
1 x=4
y=-1
2 has no solution
3 x=5y -/8 + 27/4
y= 54-8x/5
4x=y=0
5 x=2 y=1
