Answer:
V = 14 + 5t
14 + 5t ≥ 49
Lucy has to add water at least for 7 minutes.
Step-by-step explanation:
There were 14 liters of water in Lucy's fish tank. She was about to add water at the rate of 5 liters per minute until there were at least 49 liters of water in the tank.
If t represents the number of minutes she adds water and V is the volume of water in liters in the fish tank, then we can write the equation as
V = 14 + 5t ........... (1)
Now, this volume of water in the tank V must be at least 49 liters.
So, 14 + 5t ≥ 49 is the required inequality.
⇒ 5t ≥ 35
⇒ t ≥ 7
So, Lucy has to add water at least for 7 minutes. (Answer)
The fraction 91/10 is equivalent1 to 9 1/10.
This fraction is a IMPROPER FRACTION once the absolute value of the top number or numerator (91) is greater than the absolute value of the bottom number or denomintor (10). So, the equivalent fraction is a MIXED NUMBER which is made up of a whole number (9) and proper fraction (1/10).
