Answer: x=63, y=52, z=48
Step-by-step explanation:
The complete question in english is:
The sum of 3 natural numbers is 163. By subtracting the third number from the sum of the first two numbers, we get 67. By subtracting the first number from the sum of the last 2 numbers, we get 37. Determine the 3 numbers
According to this we have a system with three equations and three unknown values:
(1)
(2)
(3)
Let's begin by isolating 
from (1):
(4)
And substitute (4) in (2):
(5)
Isolating 
:
(6) We have found the first number
Substituting (6) in (1):
(7)
Adding (7) to (3):
We have the following:
Isolating 
:
(8) This is the second number
Substituting (6) and (8) in (1):
(9)
Isolating :
(10) This is the third number
What's the equation?
impulse = force times time
62=14 + 2x
62-14=2x
48=2x
48/2=x

Answer:

Step-by-step explanation:
Breakeven quantity are the number of units produced and sold at which net income is zero
Breakeven quantity = fixed cost / price – variable cost per unit
Fixed costs are costs that do not vary with output. e,g, rent, mortgage payments
If production is zero or if production is a million, Mortgage payments do not change - it remains the same no matter the level of output.
Hourly wage costs and payments for production inputs are variable costs
Variable costs are costs that vary with production
fixed cost = $2450
Variable cost = $75
price = $145
(2450) / (145 - 75) = 35
