11. The sum of three consecutive odd numbers is 63. Find the numbers.
Answers
Answer:
10. 16, 18, 20
11. 19, 21, 23
Step-by-step explanation:
10. letting the smallest even number be x,
x+x+2+x+4=54
3x+6=54
3x=48
x=16
x+2=18
x+4=20
Double Check: the 3 numbers are 16, 18, and 20, and if we add them up, we get 34+20=54. We also know those 3 numbers are all even and consecutive.
11. letting the smallest odd number be y,
y+y+2+y+4=63
3y+6=63
3y=57
y=19
y+2=21
y+4=23
Double Check: the 3 numbers are 19, 21, and 23. when we add them up we get 19+21=40+23=63. We know these numbers are all odd and consecutive.
Answer:
Here is your solution
Let,
The first even integer be:x
Then the second even integer is:x+2
Then the third even integer is: x+2+2=x+4
Sum of three consecutive even numbers =54
A/q
(x)+(x+2)+(x+4)=54
3x+6=54
3x=54-6
3x=48
x=16
now
The first integer is:x=16
the second integer is:x+2=16+2=18
the third integer is: x+4=16+4=20
Hope it helps you
