Answer:
x - y is also a rational number. Hence satisfies the closure property.
Step-by-step explanation:
Closure property of subtraction states that for any two integers a and b, (a - b) must also be an integer.
Here x and y are rational numbers. so x - y must also be rational to satisfy the closure property.

You have to add all the quantities and then dived between the numbers of amounts
Answer:
14.
There are twice as many flute players as there are trumpet players, so f = 2 × 5
15.
Let the cost of 1 tickets = be x then the equation of total cost is:
8 × x = 208
Solve for x:
x = 208/8
x = 26
Each ticket costs $26.
16.
Let the low temperature be x then the equation for high temperature is:
x + 24 = 92
Solve for x:
x = 92 – 24
Evaluate:
x = 68
The low temperature was 68°F.
17. A number is checked if it is a solution of an equation or not by substituting its value in the equation and simplifying it. If the left and right hand side of the equation are equal then the number is a solution of the equation otherwise not.
