The average of the following is 63.4

3 0

So to get the average you add them all up and then divide by how many numbers you had to add up, in this case 5 individual numbers, and added all together is 317 then divided by 5 is 63.4 (: I know someone else already answered just wanted to elaborate

Arrange these numbers from least to greatest:

zmey [24]

First let's put them all over 100.
- $\frac{5}{8}$ would change to - $\frac{62.5}{100}$

- $\frac{7}{9}$ to - $\frac{77.7}{100}$

- $\frac{4}{5}$ to - $\frac{80}{100}$

- $\frac{3}{7}$ to - $\frac{42.8}{100}$

Then if we put them from least to greatest it would be from highest to lowest (since they are negatives)

- $\frac{4}{5}$ , - $\frac{7}{9}$ , - $\frac{5}{8}$ , - $\frac{3}{7}$

The answer would be B

Solution of equation 3x-5y= 4 4x+3y=15

12345 [234]

3x-5y=4------eq1
4x+3y=15-------------eq2

multiply 3 to first eq and 5 to second eq.

9x-15y=12
20x+15y=75

subtract both eqs

29x=87 x=3 so put x in eq 1

3(3)-5y=4
5y=5
y=1
