This is what the Algebra Test 2 looks like.

**Algebra Test 2**

Write the following expressions in words.

1. 2x-9 = two

1. 2x-9 = two

__times a number decreased by (less, reduce, take away, etc.) nine.__2. 10-4x = ten

__decreased by (reduce, and decreased ONLY) four times a number.__3. 5 (x-8) =

__a number less (decreased, take away, etc.) than eight times five.__4. 7(x+5) =

__a number plus (increased, and, sum of, etc.) five times seven__Write the following statements as algebraic expressions

5. 6 centimeters more than two thirds of lenth x =

__2/3 n + 6cm__6. three times the sum of a number and two =

__3 (n+2)__7. nine decreased by two times a number =

__9-2n__8. four less than five times a number =

__5n-4__The following graph shows the first four terms of a pattern.

A) Create a chart that shows the first 10 terms of the pattern.

B) Write the algebraic expression for the relationship between the hours spent walking and the number of kilometers walked.

4n - 1

y is km walked

x is hours

C) Using your algebraic expression, determine how far they could walk after 50 hours.

4n-1

4 x 50 huors - 1 = 199 km

Done!~ Teehee!~
