Question 5.
The sum of 15 and p
Answer:
x = 15 + p,

Explanation:
An algebraic expression for the sum of 15 and p, let it be x so x = 15 + p.

Question 6.
The difference “q less than 10”
Answer:
x – q < 10,

Explanation:
Given the difference “q less than 10” is let it be x so  x – q < 10.

Question 7.
The product of r and 23
Answer:
x = r X 23,

Given divide s by 11 so let it be x so x = s ÷ 11.

Evaluate each expression for the given values of the variable.

Question 9.
3x + 5 when x = 9 and x = 12
Answer:
3x + 5 = 32, when x = 9,
3x + 5 = 41, when x = 12,

Explanation:
Given to find 3x + 5 when x = 9, so 3 X 9 + 5 = 27 + 5 = 32, when x = 12 we get 3x + 5 = 3 x 12 + 5 = 36 + 5 = 41.

Question 10.
28 – 4x when x = 4 and x = 7
Answer:
28 – 4x = 12, when x = 4,
28 – 4x = 0 when x = 7,

Explanation:
Given when x = 4 the equation 28 – 4x is 28 – 16 = 12, when x = 7 then the equation becomes 28 – 4 X 7 = 28 – 28 = 0.
