Answer:
44 hours
Step-by-step explanation:
Decreasing the people by a factor of 2 means we have 3 people
The job takes 6* 22 = 132 people hours
When we decrease the people, it will take more hours
132 people hours = 3 people * t hours
Divide each side by 3
132/3 = 3t/3
44 = t
It will take 44 hours
Answer:
6 x 340 = 2,040
Step-by-step explanation:
Answer:
x = -9
y = -8
Step-by-step explanation:
here's the solution :-
=》y = 2x + 10
=》y = x + 1
plunging the value of y from equation 1 into equation 2
=》2x + 10 = x + 1
=》2x - x = 1 - 10
=》x = -9
value of x = -9
now, plugging the value of x in equation 2, we get :-
=》y = x + 1
=》y = -9 + 1
=》y = -8
