solve fast please
answer is 2a-2b I need formula any genius
Answers
here is u r answer....
Step-by-step explanation:
a # b = 100 = (2a+2b)^2
3) 10 = (2a+2b)
4) 5 = a+b this is the important info for our answer, because we dont need to know the exact values for a or b.
5) (a + b) + 3 = 5 + 3 = 8
Given :-
Sum of three alternate numbers are 3 less than 24.
To find :-
The numbers.
What are alternative numbers?
Consecutive even or odd numbers are said to be alternative.
Example : 2 and 4. 3 and 5.
Let's solve!
Let the first number be x.
As it's clearly given in the question that they are alternative numbers, the next number will be x+2 and the third one will be x+4.
According to the question,
(x + x+2 + x+4) ≤ 24
Hence by adding 3 to the LHS(Left Hand Side) or subtracting 3 from the RHS(Right Hand Side), an equation is formed.
Method 1 :
By adding 3 to the LHS,
x + x+2 + x+4 +3 = 24
adding all the variables and constants
3x + 9 = 24
Transposing 9 to the RHS, so all the variables are on one side and constants on the other,
3x = 24 - 9
3x = 15
Transposing 3 to the RHS,
Therefore, If x is 5 then the other two numbers are :
x+2 = 5+2 =≥ 7
x+4 = 5+4 =≥ 9
Method 2 :
By subtracting 3 from the RHS,
x + x+2 + x+4 = 24 - 3
adding all the variables and constants,
3x + 6 = 21
Transposing 6 to the RHS so all the variables are on one side and constants on the other,
3x = 21 - 6
3x = 15
Transposing 3 to the RHS,
Hence the numbers are 5,7 and 9.
Verification :-
Let us verify the answer.
sum :
5+7+9 = 21
21 + 3 = 24
(or)
21 = 24 - 3
LHS = RHS
Hence verified.
