Answer:

3x - 4 = 32

Step-by-step explanation:

We solve for x to find the number (knowing that x is the unknown number).

3x - 4 = 32

3x = 32 + 4

3x = 36

x/3 = 36/3

x = 12

forsale [732]

4 1/3+7 2/4=4+1/3+7+1/2=11+(1/3+1/2)=11 5/6. For some reason, the fact that the question said 7 2/4 instead of 7 1/2 suggests that you may have misread the problem.

Find the mean of the following set of numbers:

Masja [62]

Answer:

The mean of the given set of numbers is 3.5

Step-by-step explanation:

We need to find the mean of following numbers:

8.9, 6.1, -4.8, 8.2, 2.7,-0.1

For calculating the mean the formula used is: $Mean=\frac{Sum \ of \ all \ numbers}{Total \ numbers}$

Finding sum of numbers:

$Sum \ of \ numbers= 8.9+6.1-4.8+8.2+2.7-0.1\\Sum \ of \ numbers= 21$

Total numbers = 6

So, mean is:

$Mean=\frac{Sum \ of \ all \ numbers}{Total \ numbers}\\Mean=\frac{21}{6}\\Mean= 3.5$

So, mean of the given set of numbers is 3.5
