C is the answer 12 marbles and 20 marbles
(1/25)/74=
(1/25)*(1/74)=
1/1850
Answer:

Step-by-step explanation:
we know that
The sum of the interior angles in any triangle must be equal to 180 degrees
so

substitute the given values

solve for x


Find the angle measurements



The answer is D because
60 times 5=300
20 times 8=160
25 times 9=225
33 times 10=330
Then add all of them and it gives you $1,015
Answer:
v=2-2root7, v=2+2root7
Step-by-step explanation:
-2v+8(1+2v)=-90
-2-4v^2+8+16v=-90
6-4v^2+16v=-90
-4v^2+16v=-96
v=2-2root7, v=2+2root7
