Mary practiced violin for 2 hours and her brother practiced trombone t times as long or 8 hours. Write and solve an equation to

Bond [772]

Answer:

Mary's brother practiced 4 times as long.

Step-by-step explanation:

Mary practiced violin for 2 hours.

Her brother practiced trombone t times as long or 8 hours.

t times of 2 hours = 2t hours

But, 2t = 8

Divide both sides by 2.

t = 4

Hence, Mary's brother practiced 4 times as long as Mary.
