Answer: B = (1,-9)
Step-by-step explanation:
First, I'd like to state there are many possibilties to for this solution.
Okay, 9/3 + 3 = -1b
Lets check.
PEMDAS!
9/3 is = 3
So:
3 + 3 = -1b
Then combine like terms:
6 = -1b
Following PEMDAS, divide -1 on both sides so..
-6 = b or b = -6
So, 9/3 + 3 = -1b works!!!

Answer:
The answer to your question is a) C + J + S = 80
b) C = J + 5
c) S = 45 hours
Step-by-step explanation:
a) To represent the number of hours that they work together, just add the variables and equal them to 80.
Carlito + Juan + Sara = 80
C + J + S = 80 Equation l
b) Juan worked 5 hours more than Carlito
Juan = Carlito + 5
J = C + 5 Equation ll
c) Hours worked by Sara
S = 3J Equation lll
C = J - 5
Substitute equation ll and lll in equation l to find J
J - 5 + J + 3J = 80
5J = 80 - 5
5J = 75
J = 75/5
J = 15
-Find S
S = 3(15)
S = 45 hours
