For this case, the first thing we must do is define variables:
x: number of pillowcases
y: number of sheets
We now write the system of equations:
2x + 5y = 40
x = 2y
Solving the system we have:
x = 8.9
y = 4.4
Answer:
The maximum number of pillowcases she could have purchased is:
x = 8 (spent less than $ 40)

36 divided by 2 is 18 cookies which means half the sugar, or 1 cup.
54 divided by 3 is 18, If 18 cookies need 1 cup, then 54 needs 3 cups
Answer:
38
Step-by-step explanation:
substitute the value of the variable into an equation, then simplify
Answer:
We have the following equation: y = 36 - x. And we need to find which of the following points belong to the graph:
If any of the points belong to the equation, then the equality will be met.
Then:
7 = 36 - (-13)
7 = 36 + 13
7 = 49 ❌
1 = 36 - (-35)
1 = 71❌
5 = 36 - 11
5 = 25 ❌
3 = 36 - 27
3 = 9 ❌
None of the points belong to the graph. Therefore, all points are NOT on the grah of p(x) = 36 - x.
