WITCHER [35]

Answer:

D (7a-3)/4

Step-by-step explanation:

7a – 4b = 3

Subtract 7a from each side

7a-7a – 4b = 3-7a

Arla and kal both work in jobs they get paid by the hour in their first week on the job they each worked 40 hours and together t
gladu [14]

Answer:

Arla - $15, Kal - $17.5

Step-by-step explanation:

Let $x be Arla's hourly wage and $y be Kal's hourly wage.

1. In the first week on the job they each worked 40 hours and earned $(40x+40y) together. Their total earnings were $1300, so

40x+40y=1300.

2. In the second week on the job business was slow so Arla worked 20 hours and earned $20x, Kal worked 16 hours and earned $16y, $(20x+16y) in total. Their total pool earning was $580, so

20x+16y=580.

3. Solve the system of two equations:

\left\{\begin{array}{l}40x+40y=1300\\20x+16y=580\end{array}\right.\Rightarrow \left\{\begin{array}{l}40x+40y=1300\\40x+32y=1160\end{array}\right..

Subtract them:

40y-32y=1300-1160,\\ \\8y=140,\\ \\y=\$17.5.

Then

40x+40\cdot 17.5=1300,\\ \\40x=1300-700,\\ \\40x=600,\\ \\x=\$15.
