He originally had on his MP 3 player 99 songs

Step-by-step explanation:

The given is:

  • George deleted 63 songs from his MP 3 player
  • The ratio of songs he deleted to the songs he kept was 7 : 4

We need to find how many songs he originally had on his MP 3 player

Let us solve this problem by using the ratio method

∵ George deleted 63 songs from his MP 3 player

∵ The ratio of songs he deleted to the songs he kept was 7 : 4

→  Deleted    :    Kept    :    total

→  7                :    4          :    11 (7 + 4 = 11)

→  63             :                 :    x

By using cross multiplication

∵ x × 7 = 63 (11)

∴ 7 x = 693

- Divide both sides by 7

∴ x = 99

∵ x represents the total number of songs

∴ He had 99 songs originally

He originally had on his MP 3 player 99 songs

Answer:

#1: -1.5, -0.5, 1/2, 1.5

#2:  -3, -1, 1.2, 2.3

Step-by-step explanation:

#1

First we have to figure out the correct order before we plot.

Find the biggest number:

looking at the number the biggest would be 1.5

Find the smallest number:

Looking at the number the smallest would be -1.5

Now that we have that we can easily figure out the rest...

(Going from least to greatest; like on a number line)

-1.5, -0.5, 1/2, 1.5 (That is how you will place the first one)

#2

(Use the steps from above to find the answer)

Biggest: 2.3

Smallest: -3

Order: -3, -1, 1.2, 2.3 (Placing on number line use that order)

Hope this helps :)

kobusy [5.1K]

Answer:

The answer is below

Step-by-step explanation:

An equation shows the relationship between two or more variables. An equation is a statement that shows the equality between expressions. An equation with infinitely many solution is when all numbers are solutions, that is there is no one solution. Example is: x + 3 = x + 3.

When each side of an equation has been simplified, equations that have the same coefficients and the same constants on each side have infinitely many solutions
