Rolando is 13. In five years, his age will be 3/2 the age of his sister Marisa now. How old will Marisa be in three years?

Marisa Will be 15 years old 3 years from now.

Step-by-step explanation: Rolando is now 13.

13 + 5 = 18

18 = 3/2 times age of M now.

18 = 3a/2 Solve for age.

(2)(18)=(2)(3a/2)

36/3 = 3a/3

12 = a

Marisa is 12 now. Add 3.

In 3 years, she will be 15

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
