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.
The answer would be Xx3+1 the x is ment to be the multiply sigh
Answer:
x = -12.5
Step-by-step explanation:
your goal is to get x alone so
-2x - 10 = 15
(add ten to both sides)
-2x = 25
(divide -2 to both sides)
x = -12.5
remember that whatever u do to one side of the equation, you have to do to the other so they even out!
<span>Let the age of the 4th person be F
Sum of the 1st four in line: 4(23), or 92
Sum of 1st 3: 92 - F (excludes the 4th person's age)
Sum of the last 3 in line: 3(34), or 102
</span><span>Sum of last 2: 102 - F (excludes the 4th person's age)
Sum of all 6: 6(27), or 162 (INCLUDES 4th person's age)
We now get: F + 92 - F + 102- F = 162
- F + 194 = 162
- F = 162 - 194
- F = - 32
F, or 4th person's age = -32/-1, or 32
