Answer:
1 hour and 42.85 minutes.
Step-by-step explanation:
It is found from the process of reviewing that experience survey a roadbed in 3 hours.
Hence, in 1 hour the experience survey 
of the roadbed.
Again, it is found that the apprentice survey needs 4 hours to survey the same stretch of road.
So, in 1 hour the apprentice survey does 
of the roadbed survey.
If they work together then in 1 hour, the survey work will be done by (
)= 
parts.
Therefore, the total survey they will complete working together in 
hours i.e. 1 hour and 42.85 minutes. (Answer)
(f+3)^5
(5/0)*(5/1)*(4/2)*(3/3)*(2/4)*(1/5) so the coefficients are:
1,5,10,10,5,1
1*f^5+5f^4*3+10f^3*9+10f^2*27+5f*81+243
f^5+15f^4+90f^3+270f^2+405f+243
Answer:
(-2,-5)
Step-by-step explanation:
y = 2x-1
3x-y = -1
We can use substitution
3x - (2x-1) = -1
Distribute the minus sign
3x -2x+1 = -1
x +1 =-1
Subtract 1 from each side
x+1-1 = -1-1
x=-2
Now we need to find y
y = 2x-1
y = 2(-2) -1
y = -4-1
y = -5
