3/9 + 3/9 = 6/9

We know that 6/9 can still be simplifed.

So 6/9 will be divided by three.

= 2/3 is the answer.

Hey!



To answer this question, we simply have to add straight across. But remember not to add the denominators.


Equation :

\frac{3}{9} + \frac{3}{9} = ?


Solution {Equation Solved} :

\frac{6}{9}


Now I'm not exactly sure how your instructor will accept your answer, but most prefer the final answer to be in the simplest form. So, let's convert it into a simplest form.


Simplest Form :

\frac{2}{3}


So, the correct answer to this equation is \frac{2}{3}


Hope this helps!

AB and BC form a right angle at their point of intersection. This means AB is perpendicular to BC.

We are given the coordinates of points A and B, using which we can find the equation of the line for AB.

Slope of AB will be:

m= \frac{-1-1}{14-2}=-1/6

Using this slope and the point (2,1) we can write the equation for AB as:

y-1= \frac{-1}{6}(x-2) \\  \\ 
y= -\frac{1}{6}x+ \frac{1}{3}+1 \\  \\ 
y=-\frac{1}{6}x+ \frac{4}{3} 


The above equation is in slope intercept form. Thus the y-intercept of AB is 4/3.

Slope of AB is -1/6, so slope of BC would be 6. Using the slope 6 and coordinates of the point B, we can write the equation of BC as:

y - 1 = 6(x - 2)
y = 6x - 12 + 1
y = 6x - 11

Point C lies on the line  y = 6x - 11. So if the y-coordinate of C is 13, we can write:

13 = 6x - 11
24 = 6x
x = 4

The x-coordinate of point C will be 4.

Therefore, the answers in correct order are:

4/3 ,  6,  -11,  4

Help! I have solving systems of equations using substitution, and sometimes I have equations like this:
timurjin [86]
For systems of equations try using graphing, substitution, and elimination. For example
{2x+7y=3}
{x=-4y}
You should first look at if you have a variable that can be substituted (using substitution) and in this case we do! you plug in the x into 2x meaning 2(-4y)+7y=3
1) distribute -8y+7y=3
2) combine like terms in this case -8y+7y= -1y
3) solve -1y=3
y=-3
so currently our solution is (0,-3)
now we solve for x.
we plug our solved variable (y) into 7y
7(-3) and our equation looks like this
2x+7(-3)=3
1) distribute 7(-3)=-21
2) rewrite then solve 2x+(-21)=3
3) isolate variable -21+21 & 3+21
4) 2x=24
5) solve 2/24 = 12
Meaning our solution is (12,-3)
This is how to solve by substitution.
