let's label each pump A, B, and C, just for convenience. A fills the tank by 1/50 every minute, B fills the tank by 1/60 every minute, and C drains it by 1/75 every minute. Now we can put them all into one function: t(1/50 + 1/60 - 1/75) = 1, where t = our time in minutes and 1 = the tank being full.
next, we solve for t: t = 300/7 minutes, or approximately 42.86 minutes.
Make each into improper fraction
2 x 8 + 5. = 21 / 8
3(10) + 2 = 32/3
21/8(32/3) = ((21x32)/(8x3) reduce by 3/3
(7x32)/(8) reduce by 8/8
7x4 = 28
Answer:
<h2>x = - 1/2</h2><h2 />
Step-by-step explanation:
-x + 9x = -4
8x = -4
x = -4/8
x = -1/2
The answer is: " Four hundred three and six hundred three thousandths. "
