Jim and Regina can complete one job in 4 hours when working together. When working alone, Jim works twice as quickly as Regina. • How long will it take each of them to do the job when working alone? Show all work supporting your answer.

• If Regina works as quickly as Jim, how long will it take both of them to do the job working together?

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour
