When Jose' and Sean were each 5 years old, Jose' was 1.5 inches taller than Sean. Jose' grew at an average rate of 2.75 inches per year from the time that he was 5 years old until the time he was 13 years old. Jose' was 63 inches tall when he was 13 years old. How tall was Sean when he was 5 years old?

Answer 1

Answer:

39.5

Step-by-step explanation:

let Sean age be x,let Jose age be y

x+1.5=y

13-5=8

per year 2.75,

8 yrs =2.75x8=22inches

63-22=41 inches

therefore x+1.5=y

x+1.5=41

x=41-1.5=39.5 yrs
