notice, the denominator for each fraction is the same, thus the LCD is just 3.

\bf \cfrac{11}{3}-\cfrac{2}{3}\implies \cfrac{11-2}{\stackrel{LCD}{3}}\implies \cfrac{9}{3}\implies 3

What is - 1/6 + (-7/4) this is 7th gradr math
DedPeter [7]

Hello Bubbleshi !

The first step you need to do is get everything in like terms.

- 1/6 and - 7 /4

Look at the denominator (number on the bottom)

6 and 4 go into 12, so lets check that out.

-1/6 , how can we get 12 from the denominator? Multiply it by 2.

So you multiply both the numerator (number on the top) and the denominator.

-1/6 becomes -2/12.

With -7/4, you want to get the 4 as a 12 (like terms!) so once again you multiply it by 3, and multiply the numerator as well.


-7/4 becomes -21/12.

-2/12 + (-21/12) is your final form of the problem.

You add -2 and -21 in the numerator, which is -23.

So its -23/12 which is your final answer.

Let me know if you need any more help!

Triangle XYZ is reflected over its hypotenuse to create a kite.
galben [10]

The angle between line XZ and line XY is given by:

x = atan (\frac{12}{5})\\x = 67.38

Then, the height from vertex Y to horizontal line XZ is:

h = 5 sine (67.38)\\h = 4.62

Then, the distance from Y to Y 'is given by:

YY '= 2h\\YY '= 2 (4.62)\\YY '= 9.2

Answer:

the approximate distance from Y to Y 'is:

D. 9.2 units
