1. Answer:

   Step-by-step 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.

2. Answer:

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

   Step-by-step 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.
