Answer: -836
Step-by-step explanation: Since a negative times a positive always equals a negative, (-22) · (38) equals -836.
-7r+13=-71
move 13 to the other side
sign changes from +13 to -13
-7r+13-13= -71-13
-7r= -84
divide both sides by -7 to get r by itself
-7r/-7= -84/-7
Answer: r= 12
Answer:
The total cost for 8 hours of work is $425.
The total cost for 10 hours of work is $525.
The total amount the plumber earns is made up of a fixed charge and a variable charge. A fixed charge is a charge that remains constant regardless of the number of hours the plumber works. The fixed charge is $25. The variable charge is the charge that increases per hours worked. The variable charge is $50 per hour.
Cost = fixed charge + variable charge
C = $25 + $50h
The total cost for 8 hours
$25 + $50(8)
$25 + $400
= $425.
The total cost for 10 hours
$25 + $50(10)
$25 + $500
$525.
