Question

Lennox studied twice as many hours as althea. danielle studied 5 hours less than

Answer 1

The number of hours studied by Lennox is 18 hours.

Let the number of hours studied by Danielle be h.

According to the question,

Number of hours Althea studied = (h + 5) hours

Number of hours Lennox studied = 2(h + 5) hours

Hence,

h + (h + 5) + 2(h + 5) = 31

h + h + 5 + 2h + 10 = 31

4h + 15 = 31

4h = 31 - 15 = 16

h = 16/4 = 4 hours

Hence,

The number of hours studied by Lennox  = 2 (h + 5) = 2(4+5) = 18 hours.
