Use the model to find the missing number in the pair of
equivalent expressions.
15 + 9 = ?(5+3)
What number is missing from the expression?

3

Step-by-step explanation:

15+9=24

5+3=8

8*?=24

?=3

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
