Answer:
Step-by-step explanation:
6. 13/hour
7. R=income/hours worked so 221/17=13. Not sure if that is what they are asking for.
8. Not sure. Is it $13/hour?
9. still guessing but the constant is $13/hour so to determine how many hours need to be worked to reach $1000, you divide. $1000/13=Approximately 77 hours.
Yes, they are proportional. if you divide the second fraction down to simplest form, you get 7/12, which is equal to the first fraction.
<u>Given</u>:
The system of linear equations are 
and 
We need to determine the solution to the system of equations using substitution method.
<u>Solution</u>:
The solution can be determined using the substitution method.
Let us substitute 
in the equation
Thus, we have;
Thus, the value of y is -17.
Substituting in the equation , we get;
Thus, the value of x is -13.
Hence, the solution to the system of equations is (-13,-17)
Answer: (a) $6,600
(b) $28,600
<u>Step-by-step explanation:</u>
Interest (I) = Principal (P) x rate (r) x time (t)
I = 22,000(0.06)(5)
= 6,600
Accrued (A) = Principal (P) + Interest (I)
A = 22,000 + 6,600
= 28,600
