If x = 3, what is the value of the expression 5x + 7?
Show answer
Answer: B. 22
Substitute x = 3 into the expression: 5(3) + 7 = 15 + 7 = 22.
Simplify: 8m - (3m + 2n) + 5n
Show answer
Answer: A. 5m + 3n
Distribute the negative sign: 8m - 3m - 2n + 5n. Combine like terms: (8m - 3m) + (-2n + 5n) = 5m + 3n.
What is the term in the expression 3ab - 5bc + 2ac?
Show answer
Answer: A. 3ab
A term in an algebraic expression is a single mathematical entity. It can be a single number (constant), a single variable, or a product of numbers and variables. In this expression, '3ab', '-5bc', and '2ac' are the terms.
If p = 3, what is the value of p^3?
Show answer
Answer: B. 27
To find p^3, we multiply p by itself three times: 3 * 3 * 3 = 9 * 3 = 27.
Simplify: 7p + 5q - 3p - 2q + 1
Show answer
Answer: A. 4p + 3q + 1
Combine like terms: (7p - 3p) + (5q - 2q) + 1 = 4p + 3q + 1.
