The ratio of water to orange juice to cranberry juice in a punch bowl should be 2:5:3.
den301095 [7]
Water= 2
Orange juice= 5
Cranberry Juice= 3

Since the cranberry juice is 24 ounces, and 3 ounces in the other ratio, we know that 3*8=24, so we would multiply all of the others by 8. 

Cranberry juice: 3*8=24
Orange juice: 5*8= 40
Water: 2*8=16

So our ratio would be 16:40:24

You spend $16 on 3 notebooks and x binders. Notebooks cost $2 dollars each and binders cost $5 each. Write and equation you can
marysya [2.9K]

Answer:

One equation to set up is 5x+6 = 16

That equation solves to x = 2

You bought 2 binders

==================================================

Explanation:

x = number of binders

5x = cost of all the binders only ($5 each)

2*3 = 6 = cost of all 3 notebooks only ($2 each)

5x+6 = total cost of the 3 notebooks and x binders

5x+6 = 16 is one possible equation to set up

Other equations are possible.

------------

Let's solve for x.

5x+6 = 16

5x = 16-6 ... subtracted 6 from both sides

5x = 10

x = 10/5 .... divided both sides by 5

x = 2

You bought 2 binders

-------------

Check:

1 binder = $5

2 binders = 2*5 = $10

Add this onto the $6 spent on the notebooks to get 10+6 = 16 dollars total. The answer is confirmed.
