Hello There!

Priya has a piece of string which is 5/6 yard long. She cuts 3/5 of string for a project. What is the length of the string she has left?

Left is a key word for subtract.

The equation is 5/6 - 3/5 = ?

$Solving$

The LCD ( Least Common Denominator ) is 30

5 x 5 3 x 6
--------------- - -------------
6 x 5 5 x 6

25 18 7
-------- - -------- = -------
30 30 30
[ The denominator stays the same]

So, 5/6 - 3/5 = 7/30

Hope this helped!

Sq is an angle bisector m <qst=2x and m <qsr=3x-10 what is <rst

Answer:
∠RST = 40°

Explanation:
We are given that:
SQ bisects angle RST.
This means that:
∠QST = ∠QSR
2x = 3x - 10
10 = 3x - 2x
x = 10

Therefore:
∠QST = 2x = 2(10) = 20°
∠QSR = 3x - 10 = 3(10) - 10 = 30 - 10 = 20°
Note that both angles are equal.

Now, we can get ∠RST as follows:
∠RST = ∠QST + ∠QSR
∠RST = 20 + 20 = 40°

Hope this helps :)

$as \: given \: \: 3x \leqslant - 6 \: \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: so \: \frac{3x}{3} \leqslant \frac{ - 6}{3} \: \ \\ results \: in \: x \leqslant - 2$
