Answer:

(a) 5 cm

(b) 156.5 cm

Step-by-step explanation:

1. In 5th grade, Ali was 136.5 cm, then in 6th, grade he was 141.5 cm. Now, in 7th grade, Ali is 146.5 cm. As you can see, Ali's height increases 5 cm per grade.

2. Since 9th grade is in two years, we add 10 cm to Ali's 7th grade height.

  • 146.5 + 10
  • 156.5 cm
