Answer:
7/12
Step-by-step explanation:
-15/9+9/4
We need to make them have the same denominator:
9x4= 36 so that is our new denominator
-15x4= -60
9x9=81
(Sorry if i dont make sense)
Now we have -60/36+81/36 which is equal to 21/36.
Now we simplify:
21/36=7/12
22-12=10
so this missing answer after the + is 10

Answer:
x=136
Step-by-step explanation:
To find the measure of the sum of the interior angles use the formula (n-2) times 180 where n is the number of sides.
A quadrilateral has 4 sides. (4-2) times 180. 2 times 180=360
The sum of the interior angles of a quadrilateral is 360.
x+47+95+82=360
x+ 224 = 360
x= 136
