Aaron is 4 years and Maria is 14 years old.
A = Aaron's age today
M = Maria's age today.
a. The equation based on the statement given will be:
M = A + 10
b. Maria's age based on the statement in 6 years will be:
= (A + 10) + 6
= A + 16
c. Based on the information above, the equation to solve their ages will be:
A + 16 = 2(A + 6)
A + 16 = 2A + 12
Collect like terms
2A - A = 16 - 12
A = 4
Therefore, Aaron is 4 and Maria is 14 years.

-48 is the answer to the question
mean = Summation of Data/Number of Data Added
mean = [(-54)+(-32)+(-70)+(-25)+(-65)+(-42)] / 6
mean = -288 / 6
mean = -48
60 divided by 0.4(40%)=150
=150
Answer:
2x + y = 20
Step-by-step explanation:
gradient = -2
x = 6, y = 8
y - 8 = -2(x - 6)
y - 8 = -2x + 12
2x + y = 12 + 8
2x + y = 20
