Solve (t - v)/r = k, for v

v = kr + t

-4 = 8 + k

-12 = k

c - b |1 - a|

7/10 = (3/x + 1)

23/7

5 (4a + b) + 3a + b

23a + 6b

7r + 9t

23a + 6b

Write an algebraic expression for [the difference of 5 and n cubed.

5 - n3

The sides of an equilateral triangle measure (2x + 4) units. What is the perimeter.

6x + 12

Evaluate 2x + 5y2 - 3z if x=6, y=4, and z=7

71

2t2 + 5t2 + 3t

7t2 + 3t

True or False: A linear graph can have a maximum or a minimum

False

Write a verbal expression for 4r + 9.

Four times r plus nine

a/2 + 9 = 30

a = 42

Find the solution set for 3b - 4 = 8

b = 4

5(c + 3) = 15 + 2(2c - 1)

c = -2

m - 5 = -23

m = -18

Translate m2 - 2r + 1 into a sentance

m squared minus four equals two times r plus one

10(a + 1) - 14a = 9 - (4a - 1)

null set

Solve |2x - 1| = 5. Then graph the solution set.

x = 3, x = 2 Graph <-3-2-1-0-1-2-3-4-5-6-7-8->

(-2/7)x = -16

x = 56

Determine whether 4/9 and 20/45 are equivalent ratios write yes or no

yes
