Answer:
Step-by-step explanation:
<u>Given information</u>
Paid = $15.00 / hour
Paid (Last 4 hours) = Doubled the usual pay rate
Total hour = 12 hours
<u>Given expression</u>
Wage = Pay rate × hours except for the last 4 hours + Double Pay rate × 4 hours
<u>Substitute values into the expression</u>
Wage = (15) × (12 - 4) + (15 × 2) × (4)
<u />
<u>Simplify values in the parenthesis</u>
Wage = 15 × 8 + 30 × 4
<u>Simplify by multiplication</u>
Wage = 120 + 120
<u>Simplify by addition</u>
Hope this helps!! :)
Please let me know if you have any questions
3x + y = 18
2x - y = 12
we must make both equations have only one variable
we first add the equations top to bottom, and get
5x = 30
we then divide by 5, and get x = 6
now we sub 6 in for x, and solve for y
3x + y = 18 y = 18 - 3x
y = 18 -18
y = 0
the first number is 6, the second number is 0
