The first pipe pumps out
![\dfrac{7200\text{ L}}{48\text{ min}}=\dfrac{150\text{ L}}{1\text{ min}}](https://tex.z-dn.net/?f=%5Cdfrac%7B7200%5Ctext%7B%20L%7D%7D%7B48%5Ctext%7B%20min%7D%7D%3D%5Cdfrac%7B150%5Ctext%7B%20L%7D%7D%7B1%5Ctext%7B%20min%7D%7D)
while the second pipe pumps out
![\dfrac{7200\text{ L}}{96\text{ min}}=\dfrac{75\text{ L}}{1\text{ min}}](https://tex.z-dn.net/?f=%5Cdfrac%7B7200%5Ctext%7B%20L%7D%7D%7B96%5Ctext%7B%20min%7D%7D%3D%5Cdfrac%7B75%5Ctext%7B%20L%7D%7D%7B1%5Ctext%7B%20min%7D%7D)
So together, both pipes pump out
![\dfrac{150+75\text{ L}}{1\text{ min}}=\dfrac{225\text{ L}}{1\text{ min}}=\dfrac{7200\text{ L}}{32\text{ min}}](https://tex.z-dn.net/?f=%5Cdfrac%7B150%2B75%5Ctext%7B%20L%7D%7D%7B1%5Ctext%7B%20min%7D%7D%3D%5Cdfrac%7B225%5Ctext%7B%20L%7D%7D%7B1%5Ctext%7B%20min%7D%7D%3D%5Cdfrac%7B7200%5Ctext%7B%20L%7D%7D%7B32%5Ctext%7B%20min%7D%7D)
That is, with both pipes filling the tank, it should take 32 minutes total.
I don't know what is given when I 8th May but if you can please send the answers
So H + 50.16 = -200.4? I’m not sure if I’m write but I would think -250.20 would replace H.
Answer:
Step-by-step explanation:
12x+7<-11 and 5x-8 is greater than or equal to 40
To solve
12x+7<-11
Collect like terms
12x=-11-7
12x=-18
Divide through by 12
-18/12
=--3/2 or -1 1/2
5x-8 greater than 40
5x=40+8
5x=48
Divide through by 5
=48/5
9 3/5
