Write an equation for the following statement. 

Three less than six times a number squared is seven

6x2-3 = 7

100

Solve for x. Don't forget about your negatives.

6x-12 = 12

x = 0

100

Remember the sign matters and don't forget your negatives. Solve for x.

2x-3 > 5


x>4

100

Solve for x.

|2x| = 6

x={-3, 3}

100

Solve for k.

k+j = x/y

k= x/y - j

200

Write an expression for the following statement.

Nine less than a number squared.

x-9

200

Solve for x. Don't forget about your negatives.

4(2x-8) = 64

x = 12

200

Remember the sign matters and don't forget your negatives. Solve for x. 

-5x +4< 24

x>-4

200

Solve for x.

4|3x -8|+2= 10

x = {10/3, 2}

200

Solve for k.

a+k= w-v


k = w-v-a

300

Write an expression to match the following statement.

Six times a number plus another number tripled.

6x+3y

300

Solve for x. Don't forget about your negatives.

3(x-2) = 6(5x+2)


x = -2/3

300

Remember the sign matters and don't forget your negatives. Solve for x. 

-2x+4>-2(-5x-6)

x<-2/3

300

Solve for x.

|4x-3| > 9

|4x-3|>9

4x-3>9 or 4x-3<-9

x>3  or x<-3/2

300

Solve for a.

am = p+q

a = (p+q) / m

400

Write an expression to match the following statement. 

Four more than an number and all of that tripled

3(x+4)

400

Solve for x.

-2(-2x-5) = 2(-3x+5)

x = 0

400

Remember the sign matters and don't forget your negatives. Solve for x. 

-2(3x-4) < 2(x-1)

x>5/4

400

Solve for x.

|2x+3| -7 < 2

|2x+3|< 9

2x+3<9 and 2x+3>-9

Thus, x<3 and x>-6 can also be written as -6<x<3

400

Solve for d.

d(c-a) + p= x-y

d= (x-y-p)/(c-a)

500

Write an equation for the following statement. Then SOLVE.

Six times a number is eight less than 20

6x = 20-8

x = 2

Judy wants to buy some video games. She wants one video game that costs $15, one that costs $12 and one that costs $23. She has saved $20 thus far. At her job she is working for $5 and hour. How many more hours does she need to work?

The equation you should have come up with is: 5x+20 = 50, where x is number of hours

Final Answer: 6 hours

Jim wants to buy a bike that is at least $500. He already has $125. If he saves $15 per week. How long does he have to wait to buy the bike?

The inequality: 125+15x>500 with x being the number of weeks

So x > 25

500

Write out the compound inequality and solve.

-4|2x-3|<-20

Answer: 

|2x-3|>5

2x-3 >5 or 2x-3<-5

So x>4 or x < -1
