Kamal is 17 years older than Gina. Gina is 3 years younger than Rachelle. If the sum of their ages is 77, how old is Gina?

Answer : Gina's age is 19 years.

Step-by-step explanation:

Kamal is 17 years older than Gina. Gina is 3 years younger than Rachelle.

Let Gina's age be x years

So Kamal’s age will be = x + 17

Rachelle’s age = x + 3

the sum of their ages is 77, Accordingly

x + x + 17 + x + 3 = 77

3x + 20 = 77

3x = 77 - 20

3x = 57

x = 57/3

x = 19

Thus Gina's age is 19 years,

Kamal’s age x + 17 = 19 + 17 = 36 years

Rachelle’s age x + 3 = 19 + 3 = 22 years

Gina = 19 years old

step-by-step explanation:

4(3x^2y^4)^3 (2x^3y^5)^4

=

108x^6 y^12 /16x^12 y^20

=

108 /16x^6 y^8

=

27 /4x^6 y^8
