There is another method than what the other user has pointed out (both are valid and are up to personal preference as to which are better)

For this method you need to make sure that both the denominators are the same.

(See attached image)

I hope this makes sense!

As a summary; you must make sure that both denominators of the fractions are the same. Whatever number you multiply by for the denominator, use also for the numerator.

You turn 8 5/6 and 2 1/3 into improper fractions (8 5/6 becomes 53/6 and 2 1/3 becomes 7/3)

Then you take 53/6 and 7/3 and find a common denominator which is 6
Then you multiply 7x2 and 3x2 which equals to 14/6

53/6 - 14/6 is 39/6
You can leave it as 39/6 or change it into a mixed number, if you make it a mixed number then you would get 6 3/6 which is equivalent to 6 1/2.

Line n passes through points (7, 12) and (4, 15). What is the slope of a line that
vitfil [10]
So anytime we have a slope and want to find the slope of a perpendicular line, we just have to remember a perpendicular line's slope is the negative reciprocal (reciprocal means flip the fraction). So if we had a slope of 3/4, the slope perpendicular to it would be - 4/3.


First we need to find our slope, to do this we take the change in y over the change in x like so:

(15-12)/(4-7) = - 3/4

The slope perpendicular to this is 4/3.

Which expression represents the distance between the points (a, 0) and (0, 5) on a coordinate grid?
Mashcka [7]
 \displaystyle d= \sqrt{(x_1-x_0)^2+(y_1-y_0)^2} - d is distance, (x_1,y_1) and (x_0,y_0) two points on a coordinate grid.

In our case :
(x_1,y_1)=(a,0)\\(x_0,y_0)=(0,5)

d= \sqrt{(a-0)^2+(0-5)^2} = \sqrt{a^2+25}

Simplify The Expression:<br><br> 1/8h+7-3/4h<br><br> Thank you!
ivann1987 [24]

Answer:

-5/8h + 7

Step-by-step explanation:

First you need to combine like terms (1/8h and -3/4h)

So 1/8h - 3/4h is -5/8h

Then we have our 7 left over

So the answer is -5/8h + 7
