If 5 a solution of 3x + 30 = 9x?

const2013 [10]

Answer:

x = 5

Step-by-step explanation:

This equation can be rearranged in order to easily solve.

First, rearrange the equation by simply flipping it.

3x + 30 = 9x → 9x = 3x + 30

Then, you may solve for x.

9x = 3x + 30 subtract 3x from both sides of the equation

6x = 30 divide by 6 on both sides of the equation

x = 5

Ms.Waddell put a 12-inch tall bucket under a leak in her sink. The bucket fills at a constant rate of 1/2 inch in every 1/6 of a

Angelina_Jolie [31]

Answer:

4 hours

Step-by-step explanation:

To solve this question you will simply make a ratio type equation. You know that every 1/6 of an hour, or every 10 minutes, the bucket will fill 1/2 an inch. The bucket is 12 inches tall.

$\frac{10 min}{1/2 inch} = \frac{x min}{12 inches}$

Cross multiply

$120=\frac{1}{2} x$

$x=240 min$

Convert minutes to inches

$\frac{240 min}{1} * \frac{1 hr}{60 min} = 4 hr$

Final answer: 4 hours

Hope this helps!
