12r + t - 4r + 6t (12r + 2t) - (4r + 10t)

12 (r + t) - 6 (r + t) + 4 (r + t) - 2 (r + t)

12r + t - 4r + 6t

= 8r+7t

(12r + 2t) - (4r + 10t)

= 8r−8t

12 (r + t) - 6 (r + t) + 4 (r + t) - 2 (r + t)

= 8r+8t

Step-by-step explanation:

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
