Answer;
4 or more tubes or paint.
Step-by-step explanation:
54- 8.50x > 20
-54 -54
-8.50x > -34
now you have to divide by -8.50 on both sides to get x alone.
-8.50x/-8.50 > -34/-8.50
x=4

Answer:

Step-by-step explanation:
#We know that the filling taps will run for a cumulative 4hrs each while the draining hole will empty for a combined 7hrs.
Let x be the rate of the first filling tap, and 2x of the 2nd filling tap and y be the rate of the hole.
#The rate at which the tub fills per hour is :

#The volume of the tub at the instant moment the leak is repaired is expressed as:

Hence, the volume of the tub after the leak is repaired is expressed as
