Answer:
315943/12683
Step-by-step explanation:
Well -9 2/7 * -10 3/7 is 315943/12683
350-200=150
150 divided by 25= 6

The size of ∠QTW in degrees is 72°. See the explanation below. This is based on the concept of opposite sides in a quadrilateral.
<h3>What is the logic leading to the above result?</h3>
QSUWY which is a pentagon is regular that mean:
∠QYW = 108°
The quadrilateral QTWY is a cyclic one. This means that we can apply the rule that states that opposites sides must add up to 180°
Thus, ∠QTW =
180 - 108
= 72°
<h3>What is a quadrilateral?</h3>
A closed quadrilateral has four sides, four vertices, and four angles. It is a form of polygon.
In order to create it, four non-collinear points are joined. Quadrilaterals always have a total internal angle of 360 degrees.

See the attached image for missing details.
-5x+3y=19
<span>-5x+7y=11
Here, we use substitution to solve for both variables.
Solve for y first
-5x + 3y = 19
+5x +5x
3y = 19 + 5x
y = 19/5 + 5/3x
Now plug that into the other equation. </span>-5x+7(19/5 + 5/3x) =11
-5x + 26.6 + 35/3x = 11
-5x + 35/3x = 20/3x
20/3x + 26.6 = 11
-26.6 -26.6
11 - 26.6 = -15.6
20/3x = -15.6
x = -119.6
Ahhh, now time to solve for y
-5x+3y=19
-5(-119.6) + 3y = 19
598 + 3y = 19
-598 -598
19 - 598 = -579
3y = -579
y = - 193
WE ARE DONE!!!
Answer: y = -193 and x = -119.6
