I have found that my answer is 143
Answer:
im pretty sure it'd be 76 weeks!
Step-by-step explanation:
one water tank holds 1216 and loses 5 gallons/week
another water tank holds 1520 gallons and loses 9 gallons/week
youd make an equation:
1216-5x=1520-9x
(each side being the amount of water the tank can hold minus the amount it loses per week [x])
heres how you execute the equation:
1216-5x=1520-9x
-5x=1520-1216-9x
-5x=304-9x
-5x+9x=304
4x=304
x=304/4
76
after you do the equation, you get x=76, meaning 76 weeks! :-)
An inequality for this speed sign would need to be one where x is less than or equal to 25mph. We don't have to go exactly 25mph, but it's okay if we do go exactly 25mph. We can also go less than 25mph without getting a ticket.
An inequality equation would look like this:
x < 25
***should be less than or equal sign but I don't have one on my keyboard
Hope this helped!! :)
