Answer:

3. w=P/2-L

Step-by-step explanation:

Given formula:

P=2(l + w)

Solving for w:

P=2(l + w)
P/2 = 2(l + w)/2
P/2 = l + w
P/2 - l = l + w - l
P/2 - l = w
w = P/2 - l

Correct answer choice is:

3. w=P/2-L

9514 1404 393

Answer:

Joe: 57
Scott: 19
Laura: 28

Step-by-step explanation:

Let s represent the number of orders Scott served. Then we have Joe served 3s, and Laura served (s+9). The total of orders served is ...

3s +s +(s +9) = 104

5s = 95 . . . . . . . . . . . subtract 9 and collect terms

s = 19 . . . . . . . . . divide by 5

3s = 3×19 = 57

s+9 = 19+9 = 28

Joe served 57 orders, Scott served 19, and Laura served 28 orders.
