Answer:
18
Step-by-step explanation:
Supplementary angles means sum of angles is 180.
4x + 4 + 6x - 4 = 180
4x + 6x + 4 - 4 = 180
10x = 180
x = 180 / 10
x = 18
Answer:
3x - y =13
Step-by-step explanation:
- y - y1 = m(x - x1)
- y - 2 = m(x - 5)
- distribute
- y - 2 = 3x - 15
- jump -2 across the equal sign and change the sign
- y = 3x - 15 + 2
- combine like terms
- y = 3x - 13
- use this equation to find the standard form
- y = 3x - 13
- jump the x and change the sign
- -3x + y = -13
- x must be positive, so change the sign of everything
- 3x - y = 13
Total cats: 8
Total expense: y
Expense per lion: $8,000
Total lions: z
Expense per leopard: $6,000
Total leopards: 8 - z
Therefore, the equation becomes:
total expense = number of lions × expense per lion + number of leopards ×expense per leopard
y = 8000z + 6000(8 - z)
y = 2000z + 48000
