Answer:
30 inkjet printers
30 laser printers
Step-by-step explanation:
Let x be inkjet printer
Let y be the laser printer
Total printer produced per day = 60
This implies that x+y = 60
The company has 120 labor hours per day. If it has 1 labor hour to make a inkjet printer and 3 labor hours to make a laser printer, we will have
x + 3y = 120
So we have
x + y = 60 ........(1)
x + 3y = 120 ........(2)
Subtract equation 1 from 2
We have
2y = 60
y = 60/2
y = 30
Put y= 30 into equation 1
x + y = 60
x + 30 = 60
x = 60 -30
x = 30
Therefore we have 30 inkjet printers and 30 laser printer.
So since angle A is 120, so angles B+C=60 because there are 180 degrees in a triangle. So B:C is 2:1. So angle B is 40 and angle C is 20.
Answer:
Step-by-step explanation:
2x + 10 = 28
Bringing like terms on one side
2x = 28 - 10
2x = 18
x = 18/2 = 9
Answer:
Step-by-step explanation:
Given that a group of x people rent a jeep for 80 dollars.
Since they share the amount equally we have
each person share =
When one person in the group decides not to go, each remaining person has to pay an extra 4 dollars.
i.e. now the share borne by each in the group would be

This is 4 dollars more than the original
Hence equation would be

This equation would be used to determine how many people are in the group.
Your answer will be 6. The reason it is six is that 24/6 = 4 and 4 X 6=24.
