This year, the sum of Mr. Bellini's age and his son's age is 38 years. 4 years ago, Mr. Bellini was 5 times as old as his son. How old is his son this year? How old is Mr. Bellini this year?
Let x = son's age
Let 38-x = Mr. Bellini's age (since the sum of their ages must be equal to 38)
Set up the equation using the the second statement:
(38 - x) - 4 = 5(x - 4)
Solving,
34 - x = 5x - 20
34 + 20 = 6x
54 = 6x
x = 9 years old (son's age)
38-x = 29 years old (Bellini's age)
Hope this helps~ :3
Thanks for your help Jai. ;)
this is to the people that help with answering the questions, thank you so much you don't even know how helpful u are
Well, let's do some arithmetic and clown around with the numbers.
If we let Mr. Bellini's age be "B" and his son's age be "S," according to the first statement, B + S = 38.
Now, let's move on to the second statement. It says that 4 years ago, Mr. Bellini was 5 times as old as his son. That gives us the equation B - 4 = 5(S - 4).
Now, let's solve this system of equations and find our answers.
First, let's simplify the second equation:
B - 4 = 5S - 20
B = 5S - 16
Substitute B = 5S - 16 into the first equation:
5S - 16 + S = 38
6S = 54
S = 9
So, Mr. Bellini's son is 9 years old this year.
Now, plug this value back into the first equation to find Mr. Bellini's age:
B + 9 = 38
B = 29
Therefore, Mr. Bellini is 29 years old this year.
Hope that made you smile!
To solve this problem, let’s assign variables to the unknowns. Let's say Mr. Bellini's age is represented by "B" and his son's age is represented by "S".
We know that the sum of Mr. Bellini's age and his son's age is 38 years. So, we can write the equation: B + S = 38
We also know that 4 years ago Mr. Bellini was 5 times as old as his son. This means that (B - 4) = 5 * (S - 4).
Now, we have two equations:
B + S = 38 ---(1)
B - 4 = 5 * (S - 4) ---(2)
Let's solve these equations to find the values of B and S.
From equation (1), we can express B in terms of S:
B = 38 - S
Substituting this into equation (2), we get:
38 - S - 4 = 5 * (S - 4)
34 - S = 5S - 20
Now, we can solve for S:
6S = 54
S = 9
So, Mr. Bellini's son is 9 years old this year.
To find Mr. Bellini's age this year, we substitute the value of S back into equation (1):
B + 9 = 38
B = 38 - 9
B = 29
Therefore, Mr. Bellini is 29 years old this year.
