The answer is the letter B or The area of △RST is equal to the area of △LMN.
Step-by-step explanation:
Answer: Luis’s first step was incorrect, because he flipped the inequality sign when he subtracted
Step-by-step explanation:
Given: Amelia, Luis, Shauna, and Clarence used different approaches to solve the inequality
7.2b + 6.5 > 4.8b – 8.1.
If Luis started by subtracting 4.8b from both sides ,then he would get
7.2b + 6.5 - 4.8b> 4.8b – 8.1- 4.8b
⇒2.4b + 6.5 > – 8.1. But he wrote 2.4b + 6.5 < – 8.1 by flipping the inequality sign which was not correct .
The sign of inequality get flipped if we multiply or divide a negative numbers to the both sides .
Therefore, Luis’s first step was incorrect, because he flipped the inequality sign when he subtracted.
B is the answer because it’s the one that makes most sense
