Answer:c is the correct answer
Step-by-step explanation:
A repair company's charge for repairing a certain type of copy machine fits the model y = 47.38 + 0.617x
where y is the number of dollars charged and
x is the number of minutes the repair person is on the job.
Therefore, to determine the number of minutes that it would take for the cost of repair to reach $130, we would substitute y =130 into the given model. It becomes
130 = 47.38 + 0.617x
0.617x = 130 - 47.38 = 82.62
x = 82.62/0.617 = 134 minutes
Answer:it must be a glitch
Step-by-step explanation:
Answer:
Step-by-step explanation:
We are given the equation:
and asked to solve for 
. Therefore, we must isolate the variable on one side of the equation.
is being multiplied by 5. The inverse of multiplication is division. Divide both sides of the equation by 5.
Let's check our solution. Plug 3 in for x and solve.
This checks out, so we know our solution is correct.
The solution to 5x=15 is x=3.
