The solution to this puzzle is 10+3 = 13
<h3>How to solve the puzzle</h3>
To solve this the values at the top of the star were gotten by the addition of two values inside the stars.
- 3 + 12 = 15
- 12 + 4 = 16
- 4 + 2 = 6
- 2 + 10 = 12
- 10 + 3 = 13
Therefore the answer to this question is 13.
Another way of getting the value is by adding 15 + 16 = 31
12 + 6 = 18
31-18 = 13

Answer=24 blue marbles and 3 red marbles
r=red marbles
b=blue marbles
b=3(r+5)
27=b+r
substitue b for '3(r+5)'
27=3(r+5)+r
27=3r+15+r
27=4r+15
subtract 15 from both sides
12=4r
divide both sides by 4
3=r
There are 3 red marbles
27=b+r
27=b+3
subtract 3 from both sides
24=b
There are 24 blue marbles
Answer:

9)
10)
11)
12)
13)a= d -r + c
14)
Step-by-step explanation:
4) g= c+x
x= g-c
5) u=x-k
x =u+k
6)g = c+x
x = g-c
7) 
8) g=xc

9) 12am = 4

10)-3x+2c = -3
2c = -3 +3x
2c +3 = 3x

11) am= n+p

12)
13)a-c = d-r
a= d -r + c
14)xm= np
