7AM to 10PM is 15 hours. If you take meds at 7AM you need to take 4 more times over 15 hours, or every 15/4 = 3 and 3/4 hours or 3 hours and 45 minutes. So you take at 7AM, 10:45AM, 2:30PM, 6:15 PM, and 10PM
Yes. You have to take 19 away from 4 to get to -15.

-15 14-15=-1.

16 - 1/4 = 15 4/4 - 1/4 = 15 3/4
15 acres = 94,089,600 in² so 94,089,600 in² × 4 in = 376,358,400 in³ and 376,358,400 in³ × (yd/36 in)³ ≈ 8,067 yd³
15b=4 That is the original equation.b=4/15 You need to isolate "b" and the way to do that is to divide 15 from both sides. Thus, b=4/15
Divide 15 by 4, take the answer, and move its decimal point 2 places to the right. 15/4 = 3.75 = 375%
