Answer 1

Explanation:

is the expression a numerical expression or an algebraic expression? 5x+10 is an algebraic expression

How do you know? Algebraic expressions contain variables, numbers, and at least one arithmetic operation

How many terms are in the expression? 2 terms (5x and 10)

If there is a variable, what is the coefficient on the variable?

x is the variable and 5 is the coefficient (5x)

Write the expression using words: 10 more than 5 times a number.

Hope this helped.

Answer 2

An algebraic expression. There are 2 terms. The coefficient is 5.

Explanation:

A numerical expression involves only number and excluding variables. There is a variable in this expression (x). So this is an algebraic expression.

Terms are separated by addition or subtraction. (Multiplication and division on terms doesn't make them 2 terms) so the 2 terms are 5x and 10.

The coefficient is the number the variable is being multiplied with. (Usually the number next to the variable). Here, it is obvious that 5 is the coefficient.
