If you want to know what x and y are, you need to supply us with one of the variables first!

There are 100 gallons, and to fill the tank up, we need to find the rate of increase in 40 seconds.

Let's divide 100 gallons over 40 seconds.

100/40=2.5

That means that the increase must be 2.5 gallons/second for the 100 gallon tank to be full in 40 seconds.

Nope.

20*30=600

Have a nice day!

If you find a negative slope, that's fine!

If a slope is negative, that means for every time the x-value increases, the y-value decreases.

If you are making a line, it would go down, assuming you are reading the graph left to right.

Alicia had 24, and gave 15 away, which means she now has 15 less than 24.

24-15=9

So...

Alicia has 9 cookies left.

Let's do this step by step.

5x+6=2x+15

Ok, first, subtract 2x from each side so that all xs of the problem are on one side.

5x-2x=3x

2x-2x=0

Now, we have...

3x+6=15

Next, we'll subtract 6 from each side to do the same thing.

6-6=0

15-6=9

Now, we have...

3x=9

Then, divide by 3 on each side to make the left side x.

3x/3=x

9/3=3

In conclusion, x=3.

0.4, since it goes into tenths, would become 4/10, which is reduced to 2/5.

I'm not really sure how you're going to do that but okay.

0/0 has no answer. You cannot divide something into 0 pieces, and you especially cannot divide nothing into 0 pieces.

Uh...

Here's the post.
