Add 5/9+7/9 . Simplify the answer and write a mixed number
Step2247 [10]

Hello there!

First you had to solving by the fractions parts.

\frac{5}{9}+\frac{7}{9}=\frac{12}{9}

Then you reducing by the fraction parts of 12/9.

\frac{12}{9}=\frac{4}{3}

And finally, you simplify by the fraction parts of 4/3.

\frac{4}{3}=1 \frac{1}{3}

Solution by Formulas

Applying the fractions formula for addiction.

\frac{(5*9)+(7*9)}{9*9}

\frac{45+63}{81}

=\frac{108}{81}

Simplifying 108/81 and the answer is

=1 \frac{1}{3}

Hope this helps!

How do i solve y= -5 in lines in the xy plane ? im confused .
Ilia_Sergeevich [38]

Answer:

see the explanation

Step-by-step explanation:

we know that

The equation of a horizontal line is equal to the y-coordinate of the point that passes through it  

In this problem we have

y=-5

This is a horizontal line (parallel to the x-axis)

The slope of this line is equal to zero

so

All points that pass through the line will have the same y-coordinate equal to -5

see the attached figure to better understand the problem
