Answer 1

Answer:

maria is 4.8 years old at present

Answer 2

Answer:

Maria's age is 6 yrs old

Step-by-step explanation:

m = M + 24

M = 0.2m

------

Substitute for "M" and solve for "m".

m = 0.2m + 24

0.8m = 24

m = (10/8)24

m = 30 yrs (mother's age now)

-----

Solve for "M"::

m = M+24

30 = M + 24

M = 6 yrs (Maria's age now)
