Answer:

Correct answer: x = 4

Step-by-step explanation:

If I saw your fractions right it's like this:

(2 + x) / (5 + x) = 2 / 3 => 3 (2 + x) = 2 (5 + x) => 6 + 3 x = 10 + 2 x

3 x - 2 x = 10 - 6  => x = 4

We will check

2 + 4 / 5+ 4 = 6 / 9  

When we divide both numerator and denominator

with 3 we get 2/3

If 110% of a number is 528, then the number is:
Anuta_ua [19.1K]

Answer:

c) 480

Step-by-step explanation:

Any percentage can be converted to a number ratio by dividing by 100%.

E.g. 100%/100% = 1

Following this concept, we can find the equivalent of 110% :

110%/100% = 1.1

Since 528 is 1.1 times the number we are looking for, we just need to divide 528 by 1.1 to find our number. This is because 1.1/1.1 = 1

528/1.1 = 480

Hope this helped!

Can someone help lol free points btw

Answer:

The correct answer would be C

Step-by-step explanation:

Looking at the data, you can tell that the first two are going to be wrong. The minimum is 1, and the maximum is 5.

A mode, by definition, is the number that appears most in the data. According to answer D, 3 appears 3 times in the data. That is incorrect, as 3 only appears twice in the data.

This leaves only answer C. We need to make sure it's correct. The answer mentions the mean as a value between 2 and 3. Mean is the average. To find the average, you must add all the values together first.

1 + 2 + 5 + 3 + 2 + 2 + 5 + 3 = 23

Then, you must divide the value by the number of data given. There are 8 numbers here, so you must divide 23 by 8.

23/8 = 2.875

2.875 is between the numbers 2 and 3 like answer C said, so C is correct.
