Answer:An expression is one or more terms in an algebraic phrase. An expression does not contain the = sign because it is a phrase. Some examples of algebraic expressions are 2x, 5x + 3, 8m - 5m + 10
Evaluate an Algebraic Expression
To evaluate an algebraic expressiontext annotation indicator for x = 3, means to replace the variable x with the number 3 and then simplify by following order of operations.
Example:
Evaluate the following expression for x = 3.
3 xtext annotation indicator + 5
3(3) + 5text annotation indicator
= 9 + 5
= 14
Write an Algebraic Expression
To write an algebraic expression, look for key words that tell you what operation (add, subtract, multiply, or divide) to use.
Example:
Write an algebraic expression for: The product of x and 5 .
The key word here is product . You may recall that a product is the answer obtained when you multiply. That means we want to multiply x and 5, so we write the expression as 5 x . It should be written the standard way by putting the coefficient in front of the variable.

9. angle x=80
I think this is the answer, sorry if it isn't let me know.
I don't see any question there ... just a bunch of pretty rulers.
I'm going out on a limb here, and I'm gonna assume that the question is "Identify the number to which the arrow on each ruler is pointing.".
If that's the question, you're welcome. If not, ignore everything I'm about to say.
Orphan ruler on page-1: 6 and 1/4
Rulers on page-2, starting at the top and working down:
6 and 3/8
1
3 and 5/8
2 and 1/2
7 and 3/4
4 and 7/8
5 and 1/8
9 and 1/2 .
If these answers are not helpful, remember: I'm the one who had to invent the question, and for the question that I invented, these answers are all correct !
