4 * 45 = 180
265 - 180 = 85
85/5 = 17
They sold 17 rolls of patterned wrapping paper.
Answer:
No
Step-by-step explanation:
To determine if (- 5, - 5) is a solution
Substitute x = - 5 into the inequality and compare answer to y
- 2(- 5) + 4 = 10 + 4 = 14 > - 5 ← the y- coordinate
Thus (- 5, - 5) is not a solution to the inequality
Answer:
Check step by step explanation
Step-by-step explanation:
a) Let x represent the amount of rides she takes, the 6 and 2.5 represent the amount of money required to enter
A(x) = 1.5x + 6
B(x) = 2x + 2.5
b) You can find this by making the 2 equations equal to each other and solving for x
1.5x + 6 = 2x + 2.5
3.5 = .5x
7 = x
7 rides make them equal cost
c) Plug in 5 for each of the equations and find out which one is cheaper
A(5) = 1.5 * 5 + 6
A(5) = $13.50
B(5) = 2 * 5 + 2.5
B(5) = $12.50
Carnival B is cheaper
2/x-9. You must divide 2 by x first to follow the order of operations then subtract by nine.
