The ratio of red tacks to blue tacks on the bulletin board is 3 to 5. There are 50 blue tacks. How many red tacks are there?
bazaltina [42]

Answer:

If we want our ratio to stay the same (3 to 5), we'll need to pair a set of 3 blue tacks with every set of 5 red tacks. In a group of 50, we can make 10 groups of 5 red tacks, so we'll also need 10 groups of 3 blue tacks, which gives us a total of 30 blue tacks

Will ran 120 minutes in the past two days. He ran 20 more minutes the second day than the first day. how many minutes did he run
valentinak56 [21]
Here is the equation: x+(x+20) = 120

Since you can't combine anything yet, its x+x+20=120

You need to get x by itself

Minus 20 from both sides

Its x+x=100 now

Combine the x's which is now 2x

Now divide 100 by 2 which is 50

x=50
---------------

Lets check:

50+(50+20)=120

Now combine the numbers in the parentheses

Its now 50+70=120

50+70=120 and 70-50=20

As you can see, he ran 50 minutes the first day and 70 minutes the second day
