Answer:A) yes,B)4.50n<135
Step-by-step explanation: should would make profit because you would take the answer you got from 12n > 135 + 4.50n to see work look below
- 12-4.50=7.5
- 7.5n>135
- 7.5/135=184
- 18*15=270
the answer for part b would be to see work look below
- set up equation(4.50n<135)
- 4.50/135
- anwer is n<30
hope I helped!!!!!
Answer:
The solution to the system of equations is:
x = 2, and y = -1
Explanation:
Given the pair of equations:
4x + 5y = 3 ..........................................................................(1)
2x + 3y = 1............................................................................(2)
To solve this by elimination:
Multiply equation (2) by 2, to eliminate x
Equation (2) becomes
4x + 6y = 2 .........................................................................(3)
Subtract equation (1) from (3)
4x - 4x + 6y - 5y = 2 - 3
y = -1 ....................................................................................(4)
Multiply equation (1) by 3 and equation (2) by 5 to eliminate y
Equation (1) becomes
12x + 15y = 9 .......................................................................(5)
Equation (2) becomes
10x + 15y = 5 ........................................................................(6)
Subtract equation (6) from (5)
12x - 10x + 15y - 15y = 9 - 5
2x = 4
Divide both sides by 2
x = 4/2 = 2 ............................................................................(7)
From equations (7) and (4)
x = 2, and y = -1
Answer: I think the answer is 80x + 60y < or equal to 1,000 (the first answer)
