I'm pretty sure this is the answer:

Subtract the 32 from both sides then divide both sides by 9/5. There is a negative so you would flip the inequality sign then your answer will be - 1.6 or -8/5

Answer:

c < − 40

Step-by-step explanation:

The inequality we're given to start with is:

9/5 C + 32 < -40

The steps to solve this are:

Step 1: Subtract 32 from both sides.

9 /5 c + 32 − 32 < − 40 − 32

9 /5  c < −72

Step 2: Multiply both sides by 5/9.

(5/9)*(9/5 c) < (5/9)*(-72)

Final answer:

c < − 40
