Read Solution (Total 10)
-
- Let three consecutive odd integeres be
x,x+2,x+4
4x=6+2(x+4)
x=7
x+4=11 - 7 years agoHelpfull: Yes(24) No(2)
- 11: let no. be a-2 , a , a+2 be three consecutive odd integers. then 4(a-2) = 6 + 2(a+2)
solving we get a=9;
third no. : a+2 so 9+2=11; - 7 years agoHelpfull: Yes(4) No(1)
- d)11
4(7)=(6+11*2)
Here_the three consecutive ood integers are 7,9,11. - 7 years agoHelpfull: Yes(2) No(1)
- Ans is 11
4(2n+1)=2(2n+5)+6 solving this we get n=3.
So third integer is 11 - 6 years agoHelpfull: Yes(1) No(0)
- let 3 consecutive odd number be:
(2n+1), (2n+3), (2n+5)
according to given condition:
3(2n+1)=2(2n+5) + 6
therefore n=3
so 3 numbers are 7,9,11 - 3 years agoHelpfull: Yes(1) No(0)
- Take the odd number is n,
next odd number is n+2,
next odd number is n+4
4n=2(n+4)+6
4n=2n+14
n=7
n+4=11 - 7 years agoHelpfull: Yes(0) No(0)
- 11
c=a+4
according to que
4a = 2c+6
after solving we get c = 11 - 7 years agoHelpfull: Yes(0) No(0)
- 11 is the answer
- 5 years agoHelpfull: Yes(0) No(0)
- Let us assume the three odd integers
a,a+2,a+4
Given four times the first of three consecutive odd integers so…
4a= 6+2(a+4)
4a = 6+2a+8
4a-2a = 14
2a = 14
a = 7
Hence
a+4= 7+4=11
11 is the answer - 2 years agoHelpfull: Yes(0) No(0)
- a, a+2 ,a+4
4a = 6+2 (a + 4)
4a = 6+ 2a + 8
4a - 2a = 14
2a = 14
a = 7
hence
a + 4 = 7 + 4 = 11
hence proved - 1 year agoHelpfull: Yes(0) No(0)
