Answer:
Step-by-step explanation:
3a + 26 = 86
3a = 86 - 26 = 60
a = 60/3 = 20
Answer:
Step-by-step explanation:
If Daniel does 1/9 of the job in one hour
let x = Paul's rate
Paul does 1/x of the job in one hour
They both do the job in 4.95hrs
(1/9)(4.95) + (1/x)(4.95) = job completion
multiply both sides by 9x
(9x)(1/9)(4.95) + (9x)(1/x)(4.95) = 9x(1)
4.95x + 9*4.95 = 9x
4.95x + 44.55 = 9x
9x - 4.95x = 44.55
4.05x = 44.55
x = 44.55/4.05
x = 11 hours i.e time it takes for Paul to pick the 40 bushels alone

Answer:
Step-by-step explanation:
Let the equation of the line be: 
where m is the slope and b is the y-intercept.
The given straight line has a y-intercept at 
The equation is of the form 
The line passes through the point (2,4).
Let us substitute x=2, and y=4 to find the value of m.
The slope is 
Hence the equation of the line is
