9514 1404 393

Answer:

  x = 6

Step-by-step explanation:

The parallel lines divide the sides proportionally. So, we can write the equation ...

  x/4 = (x +3)/6

  3x = 2(x +3) . . . . . multiply by 12

  x = 6 . . . . . . . . . . . subtract 2x

Given 5 blue marbles, 3 red marbles and 2 white marbles. Find the probability of choosing a red marble given that its not white
Maslowich

Answer:

The chances you will get a red marble over a white or blue marble is 30%

Step-by-step explanation:

If you add 5 + 3 + 2 you will get 10

You then turn it into a fraction

3/10 is the chance you will get a red over a blue or white, now we need to convert it into a percentage by turning to 10 into 100 and multiplying 3 x 10

Once you have done that you should have 30/100

Take the 100 away and turn it into a percentage

The answer would be 30%

What's 4*72 rewritten using the distributive property?
NemiM [27]
4*72=288 is the first step you do. I then decided to do 72/4 which is 18 to get the inside number. 4(18*1) is what I got finally because when you do distributive property 4*18=72 and 481=4. Once all of that is done, you come right back to the same problem you had at first.
