Sandy: 10x + 5
Kimmi: 25x

If we want to know when the fees will be the same, we set the equations equal to each other and solve for x:
10x + 5 = 25x
5 = 15x
x = 3
So the number of children has to be 3.

Which graph shows that Cindy reads about 3/4 of the time while riding in the car?
wolverine [178]

The graph that shows a unit rate of 3/4, which is the time Cindy reads while riding in the car is the graph attached below.

<h3>What is Unit Rate?</h3>

Unit rate can be described as a constant or exactly how much of one quantity is per 1 unit of another quantity.

Unite rate (k) = x/y.

In the graph attached below, when x (hours driving) = 3, y (hours reading) = 4.

Therefore, unit rate = 3/4. We can then conclude that the graph that shows that Cindy reads 3/4 of the time she rides in a car is the graph attached below.

A 24,000-gallon pool is being filled at a rate of 50 gallons per minute. At this rate, how many minutes
deff fn [24]

Answer: 480 minutes or 8 hours

Step-by-step explanation:

24,000 ÷ 50 = 480.

It will take 480 minutes to fill the pool.

480 minutes ÷ 60 is also 8. So it will take 8 hours to fill the pool, or 480 minutes. Whichever one you want to use.

Hope this helps!

Select the correct answer. Given the following formula, solve for a. A. B. C. D. <br> s=a+b+C/2
nexus9112 [7]

Hey there!

The answer to your question is a = s - b - C/2

<u>To solve for "a", we must get "a" on it's own side of the equal sign.</u> We can first subtract "s" from both sides:

<em>0 = a + b + C/2 - s</em>

Then, we can subtract a from both sides:

<em>-a = b + C/2 - s</em>

Finally, we divide both sides by -1, so a is by itself.

<em>a = -b - C/2 + s</em>

And we can rearrange it to the standard form:

a = s - b - C/2

Good luck, and hope it helped! Have a great day!
