find three consecutive odd integer such as that the sum of the first number tow less than the second number and three more than the third number os 70
Answers
Answer:
Hence, the three consecutive odd integers are 9,11,and 13.
Answer:
9,11,13
Step-by-step explanation:
Given :The sum of the first, twice the second, and three times the third = 70
To find : The three consecutive odd integers.
Proof:
Let the first odd integer = x ,
The second consecutive odd integer = x+2 ,
The third consecutive odd integer = (x+2)+2 = x+4
So,The sum of the first, twice the second, and three times the third will be
x+2(x+2)+3(x+4)
Given the sum of the first, twice the second, and three times the third = 70
∴ x+2(x+2)+3(x+4) = 70
=> x+2x+4+3x+12 = 70
=> 6x+16 = 70
=> 6x = 70-16
=> 6x = 54
=> x = 54÷6
=> x = 9
Now we have;
first odd integer = x
=> x= 9
The second consecutive odd integer = x+2
=> x+2
=> 9+2 = 11
=> x = 11
The third consecutive odd integer = x+4
=> x+4
=> 9+4 = 13
=> x = 13
∴ the three consecutive odd integers x=9, x=11, x= 13.
Hence, the three consecutive odd integers are 9,11,and 13.
