Answer:

8 minutes

Step-by-step explanation:

Since the level of the tank needs to be at two-thirds its original level, then this means that Andrew needs to drain only one-third of the fish tank. Therefore the amount of time it would take can easily be solved with this 2-step equation...

6t = 144 * \frac{1}{3} .... first multiply the right side of the equation

6t = 48   ... next divide both sides by 6

t = 8

Finally, we can see that it will take Andrew 8 minutes to drain the tank to two-thirds of its original level.

Answer:

equation: 4x+6=9

x=0.75

Step-by-step explanation:

4x+6=9

subtract 6 from both sides

4x+6-6=9-6

4x=3

divide by 4 on both sides

4x÷4=3÷4

x=0.75

I can't seem to figure this out
lesya [120]
To answer this question, you would need a protractor, which is a device that measures angle. Because this is a picture, I cannot help you. I'm sorry....

What I can tell you is that the angle is less than 90 degrees.
