Write the inequality from the graph

X greater than or equal to -1

Write the inequality from the graph

X is not equal to zero

2/15 = x/10

X= 4/3 or 1 and 1/3

5/11= 9/x

X= 99/5 or 19 and 4/5

6/x= 9/21

X=14

a - 1 greater than or equal to 3

a greater than or equal to 4

true or false- the equation 3(5x + 4)=27 can be simplified to 15x + 4 = 27

false 15x + 12 = 27

true or false- two consecutive integers would be represented with n and 2n

false n + 1

true or false- the inequality -2x > 8 is equivalent to the inequality x > -4

false x < -4

5m + 2m= 28

m= 4

3n - 9= 3(-9)

n= -6

p/2 + 6 = 12

p=12

true or false- an inequality with two inequality symbols is called a compound inequality

true

true or false- the inequality -3< x is equivalent to the inequality x > -3

true

Hunter is four years older than his sister Elizabeth. If the sum of their ages is 18, how old is Hunter?

x + (x+4)= 18 age 11

4x + 3= 21 -2x

x= 3

5x + 3 = 18

x= 3

3x + 4 = 10(x-1)

x=2

-3y-2 less than or equal to 10

y less than or equal to -4

two thirds times y = 8

y= 12

5y + 4 - 4y= 12

y=8

10 < 2x + 8 less than or equal to 16

1< x less than or equal to 4

x- 8= 14

22

Rachel owns 4 fewer than twice as many pairs of shoes as her friend Nicole. If Rachel has 14 pairs of shoes, how many pairs of shoes does Nicole have?

2n - 4= 14 9 pairs
