Use the image to answer the question. Paolo solved an inequality and graphed the solution on the number line. Which of the following inequalities did he solve? (1 point) Responses 2.8x<10.5 2.8 x less than 10.5 3.7x>14.8 3.7 x greater than 14.8 2.1x<8.4 2.1 x less than 8.4 4.9x>19.6

Based on the image, it appears that Paolo solved the inequality 2.1x < 8.4. Therefore, the correct answer is "2.1x<8.4" (2.1 x less than 8.4)
