Simple....

you have:

5 \frac{2}{5} +2 \frac{10}{13}

to convert them into improper fractions:

1.) Take whole number*denominator 

(5*5=25)

2.) Take what you got...and add the numerator

(25+2=27)

3.) Use the original denominator

\frac{27}{5}

Do the same to the other one...

2*13=26

26+10=36

\frac{36}{13}

Now..add...

\frac{27}{5} + \frac{36}{13}

But..you need a common denominator!

\frac{27}{5} * \frac{13}{13}= \frac{351}{65}

\frac{36}{13} * \frac{5}{5} = \frac{180}{65}

Now you can add!

\frac{351}{65} + \frac{180}{65} = \frac{531}{65}

When simplified....

8 \frac{11}{65}

Thus, your answer.

Which relationship has a zero slope
vesna_86 [32]

Answer:

The first table.

Step-by-step explanation:

A slope of 0 means that as x increases, y stays the same.  In the first table, all of our y-values are 2; this means that y stays constant.  

To prove it, we use our formula for slope:

m=\frac{y_2-y_1}{x_2-x_1}

The slope of the line between the first two points is

(2-2)/(-3--1) = 0/-2 = 0

The slope of the line between the second pair of points is

(2-2)/(-1-1) = 0/-2 = 0

The slope of the line between the next pair of points is

(2-2)/(1-3) = 0/-2 = 0

Since the slope between each pair of points is 0, the slope of the entire line is 0.
