2 A garden hose supplies 36 gallons of water in 3 minutes. Use a table or eq
Vilka [71]

Answer  ↣ 12 gallons per minute

Step-by-step explanation ↣ Ok I'm gonna use ratios because I can't draw a graph here.

Ok so if the garden hose supplies 36 gallons of water in 3 minutes, then the ratio is 36:3 because every 3 minutes the garden hose "sprays" 36 gallons.

To simplify this ratio, you need find the amount of water the garden hose supplies in 1 minute.

Well to get from 3 to 1, you have to divide by 3.

Do the same thing to 36. 36/3 equals 12.

So the final ratio is 12:1

This is the unit rate. The unit rate is when one variable is 1 unit (most of the time it is speed).

You can multiply 1 by any number and multiply 12 by the same number.

Here are some ratios...

m=minutes

g=gallons

1m:12g

2m:24g

3m:36g

4m:48g

5m:60g

Hope this helped!

BTW why do I sound like this I'm not a aesthetic person-

I need to explain/show work.<br> Help please
Fittoniya [83]

Answer:

adult tickets = 17, children tickets = 9

Step-by-step explanation:

Let x be the number of children and y the number of adults

Then given that 26 tickets are sold, we can write

x + y = 26 → (1)

Given that ticket cost was $194 we can write

5.5x + 8.5y = 194 → (2)

Rearrange (1) expressing y in terms of x by subtracting x from both sides

y = 26 - x → (3)

Substitute y = 26 - x into (2)

5.5x + 8.5(26 - x) = 194 ← distribute and simplify left side

5.5x + 221 - 8.5x = 194

- 3x + 221 = 194 ( subtract 221 from both sides )

- 3x = - 27 ( divide both sides by - 3 )

x = 9

Substitute x = 9 into (3) for corresponding value of y

y = 26 - 9 = 17

Hence number of adult tickets sold = 17

number of children tickets sold = 9
