It would be 25.
x multiplied by 2 is 10. Hint hint, it's 5.
5 x 5 (boys) is 25.
Hope it helps!
For a solution to exist the x and y values must be equal at that point.
I'll solve both for y first (and there are other ways to do this of course)
2x+4y=1, 4y=1-2x, y=(1-2x)/4
3x-5y=7, -5y=7-3x, y=(3x-7)/5
Since y=y at the solution point we can say:
(1-2x)/4=(3x-7)/5 cross multiplying...
5-10x=12x-28
-22x=-33
x=3/2 or if you prefer 1.5, now we can solve for y using either origianl equation...
2(1.5)+4y=1
3+4y=1
4y=-2
y=-0.5
So the solution is the point (1.5, -0.5)
The answer is 2.5 cm
First, you multiply 4 and 12, and you get 48
Then you take 120 and you divide it by 48.
This leaves you with 2.5
To check you multiply 2.5, 4, and 12
Answer: 
Step-by-step explanation:
Given
The total no of beads is 52
there 13-red,13-blue,13-green, and 13-black
favorable outcomes to select a blue bead is 13
Total outcomes are 52
Probability is given by
