Answer: 4

Count the number of intersections in each figure.
The first figure has 9 intersections, and it equals 9.
The second figure has 1 intersection, and it equals 1.
The third figure has 4 intersections, so it equals 4.

Answer: 30

Let's denote: Bull = B, Horse = H, and Dog = D.
From the given equations:
B + H + H = 50
B + B + B = 60
D + D + H = 5
D + B + H = ?
Solving equation 2, we get:
3B = 60
B = 20
Substituting B = 20 in equation 1, we get:
20 + 2H = 50
2H = 30
H = 15
Substituting H = 15 in equation 3, we get:
2D + 15 = 5
2D = -10
D = -5
Finally, substituting B = 20, H = 15, and D = -5 in equation 4, we get:
-5 + 20 + 15 = 30
Answer: 30

Answer: 64

To solve this, let's assign variables to each image: Purple cupcake = A, Cupcake with cherry = B, and Sandwich = C.
Now, let's write the equations based on the given information:
A + B = C
B = 12
C = 16
Substitute the known values into the first equation: A + 12 = 16.
Solve for A: A = 16 - 12 and A = 4.
Now, we need to find the value of A x B + C:
4 x 12 + 16 = 48 + 16 = 64
So, the missing number is 64.
