Answer:
12/5 days
Step-by-step explanation:
if d=number of days
w=work completed
person one completes w=d/6 (ie. after 6 days (when d=6) work will be completed (w=1))
person two completes w=d/4 (ie. after 4 days (when d=4) work will be completed (w=1))
so total work competed together w=d/6 + d/4
the job is complete when w=1 so
1 = d/6 + d/4
12 = 2d + 3d
12 = 5d
d = 12/5
4/5 and 40/50 are both equivalent
Answer:
easy
Step-by-step explanation:
The equation you wrote has no solutions since the left hand side is equal to 6x-10 and the right hand side is equal to 6x+8
3/x = 4/3
4x = 9
x = 9/4
5/y = 4/3
4y = 15
y = 15/4 (B)
