The time to complete a project varies inversely with the number of employees. If 3 people can
complete the project in 7 days, how long will it
take 5 people?
O 4.2
O 21
O 11.7
O 2.1

4.2

Step-by-step explanation:

T = K/N

K= TN

= 3×7

K= 21

Therefore the time required for 5 employees can be calculated as follows

T= 21/5

= 4.2

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)

step-by-step explanation:

*calories burned = (weight)(calorie factor)*

calories burned = 180 (0.65)

calories burned = 117

the calories he used up is 117, which is 65% of his weight.
