Question

Arthur, Kyle, and Tom are all on the baseball team. At the end of the season, they compared how many home runs each of them hit. Arthur noticed that if he doubled the number of home runs he hit and then subtracted 1, he would get the number of home runs Kyle hit. Tom noticed that if he subtracted 1 from the number of home runs he hit and then doubled that number, he would get the number of home runs Kyle hit. Write an expression representing the number of home runs Kyle hit in terms of the number of home runs Arthur hit, a. Enter your response in the first response box. Write an expression representing the number of home runs Kyle hit in terms of the number of home runs Tom hit, t.

Answer 1

k = 2a - 1

k = 2(t - 1)

Explanation:

Let :

Number of home runs Arthur hit = a

Number of home runs Kyle hit = k

Number of home runs Tom hit = t

Kyle's home runs, k in terms of Arthur's home run : Double the value of a ; then subtract 1

k = 2a - 1

Kyle's home runs in terms of Tom's home runs ;

Subtract 1 from t `

k = 2(t - 1)
