Step-by-step explanation:
5 - 3/20 equals 4 17/20.
There are 20/20 in one whole.
You have 5 wholes(80/20) and you are subtracting 3/20, leaving 77/20.
77/20 equals 4 17/20
Direct variation problems use the equation y = kx
Replace y and X with the two known numbers to solve for k:
6=k9
Solve for K by dividing both sides by 9:
k = 6/9, reduces to 2/3
Now replace y and k into the formula to solve for x:
15 = 2/3x
Solve for X by dividing both sides by 2/3:
X = 15 / 2/3
X = 45/2 as an improper fraction, 22 1/2 as a proper fraction or 22.5 as a decimal.
Not sure which format the answer needs to be in, so I gave all three.
Answer:
The first answer choice= y = 50x
Step-by-step explanation:
Because you find a point on the graph that is exactly on a point and divide the y by the x and you get the constant. THen in the answer choices only y = 50x is a larger number than 25 which in this case is the constant!

Answer:
It will take 8 hours for the 5 workers to complete the same job.
Step-by-step explanation:
The amount of work done is the same for both crews.
Work = time * workers
Work = 10 * 4
Work = time * 5
Set the two equal
10 * 4 = time * 5
Divide each side of the equation by 5
10*4/5 = time *5/5
8 = time
