Answer:
I got 17.
Step-by-step explanation:
Because it takes 4 days to make 20 small frames, it takes 8 days to make 40. And because it takes 3 days to make 21 frames, and 21 multiplied by 3 is 63 (one less than 64), it would take 9 days (3 times the amount for 21) to make 64 large frames. In all, it would take APPROXIMATELY 17 days (9 +8 is 17)
A. -5x + 3y = 15 is your answer. this is because the slope is 5/3 and the y-intercept is 5 so you plot those onto the graph and this shows it.
hope this helps, God bless!

The concept that can be used in order to answer this item is that of man-days. The total number of man-days required to do the job should always be constant.
This can be illustrated by the givens above.
Scenario 1:
N1 = (4 employees)(4 days) = 16 man-days
Scenario 2:
N2 = (2 employees)(8 days) = 16 man-days
The equation for determining the value of e is equal to,
k = (d)(e)
The answer is the second choice.
It might be no solution:
steps-
x=5-y
x+y=15
substitute the x(which is the top problem) into the second one.
(5-y)+y=15
cancel it out
(5-y)+y=15
-5. -5
a negative plus a positive is gonna equal 0
-y+y=15-5
0=10
that is no solution..
