Answer:

5v + 3 = 5v – 5

Step-by-step explanation:

In an equation, if the variable is cancelled and we get a statement that is false, the equation has no solution.

5v+3 = 5v-5

Since we have a variable on both sides, our first step would be to subtract 5v from each side:

5v+3-5v = 5v-5-5v

3 = -5

There is never a time that 3 is equal to -5; thus there is no solution.

The first one:
5v + 3 = 5v - 5
Subtract 5v from both sides ->
3 = -5
This isn't true so that means there are no solutions...

find the mean, median, and mode of he data set. round to the nearest tenth. 7, 5, 4, 2, 1, 1, 2, 3, 5, 4, 5

Hello!

First you need to list the numbers from least to greatest

1, 1, 2, 2, 3, 4, 4, 5, 5, 5, 7

To find the mean you add all the numbers up and divide the sum by the amount of numbers added

1 + 1 + 2 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 7 = 39

39 / 10 = 3.9

The mean is 3.9
------------------------------------------------------------------------------------------------------
To find the median you find the number in the middle

The median is 4
------------------------------------------------------------------------------------------------------
The mode is the number that appears the most

The mode is 5

Hope this helps!
