Keiko, aldo, and henry sent a total of 50 text messages during the weekend. aldo sent 2 times as many messages as henry. keiko s
ent 10 fewer messages than henry. how many messages did they each send?
1 answer:
K + a + h = 50
a = 2h
k = h - 10
(h - 10) + 2h + h = 50
4h - 10 = 50
4h = 50 + 10
4h = 60
h = 60/4
h = 15 <=== Henry sent 15
a = 2h
a = 2(15)
a = 30 <=== Aldo sent 30
k = h - 10
k = 15 - 10
k = 5 <=== Keiko sent 5
