Answer the problem below:
Jeff is 10 years old and his brother is 2 years old. In how many years will jeff be twice as old as his brother?
Answers
Answer:
6 year later
Step-by-step explanation:
Let Jeff will be twice older than it's brother after A year
Therefore 2(2+a)=10+a
4+2a=10+a
2a-a=10-4
THEREFORE a=6
So, after 6 year Jeff will be twice as its brother..
Answer:
Jeff will be twice as old as his sibling in x years. We can write out an equation to find x: Algebraic approaches with reasoning.
Step-by-step explanation:
To calculate how old Jeff will be in x years, multiply two by (his sibling's age in x years).
Jeff is now ten years old, and his younger brother is two. Inputting the numbers into the equation allows us to:
10 + x = 2 * (2 + x)
Putting it simply:
10 + x = 4 + 2x
When x is taken away from both ends:
10 = 4 + x
By taking away four from each number:
6 = x
Thus, Jeff will be twice as old as his sibling in six years.
Algebraic approaches may be used to solve for the unknown variable in this case. Algebra allows us to get answers by setting up an equation using the information in the problem and then identifying the variables. Using mathematical reasoning and critical thinking abilities to tackle real-world situations is also emphasized here.
