(C) 11
(D) 22
(E) 33

Answer 1

Answer:

B. 10

Step-by-step explanation:

Three wheels plus two wheels is 5. 10 multiply 5 is 55.

Answer 2

Step-by-step explanation:

Since, they both are equal. We may assume as a single variable i.e (x).

• Number of wheel in tricycle = 3
• Number of wheel in bicycle = 2

3x + 2x = 55

5x = 55

x = 55/5

x = 11

No. of tricycle = 3x = 3(11) = 33.
