(PLEASE HELP FAST!!!) Consider the expression 5x + 10.

Is the expression a numerical expression or an algebraic expression? How do you know?
How many terms are in the expression?
If there is a variable, what is the coefficient on the variable?
Write the expression using words.
Answer in complete sentences.

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.

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.

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
