D = r t
384 = 640 * t
384/640 = t
.6 = t .6 of an hour
.6 hr * 60min/1 hr = 36 minutes (just in case it needs to be in minutes)
4x + 2 < 14
4x < 14 - 2
4x < 12
x < 12/4
x < 3
S = { x <3 }
Do you have any pictures?
Answer:
T = total #
T = 5 (to the aunt) + 1/2 (T - 5) (to his friends) + 1 (to his sister) + 4 (left)
T = 5 + 1/2 (T - 5) + 1 + 4
T = 10 + 1/2 (T - 5)
2T = 20 + (T - 5)
2T = 20 + T - 5
2T = 15 + T
T = 15
