Question 786927
find two consecutive even integers such that six times the first equals five times the second 
-----
1st: 2x
2nd: 2x+2
----
Equation::
6(2x) = 5(2x+2)
12x =10x + 10
2x = 10
x = 5
-----
1st: 2x = 10
2nd: 2x+2 = 12
================================
do there exist 7 consecutive integers with the sum of 130. explain.
Equation:
1st: x-3
2nd: x-2
3rd: x-1
4th: x
5th: x+1
6th: x+2
7th: x+3
--------
sum = 130
7x = 130
x = 18.57
-----
That is not an integer.
Ans: No
=====================
three consecutive odd intgers are such that the sum of the first and the third is 70. find the integers
----
1st: 2x-1
2nd: 2x+1
3rd: 2x+3
------
Equation:
(2x-1)+(2x+3) = 70
4x+2 = 70
4x = 68
x = 17
----
1st: 2x-1 = 34-1 = 33
2nd: 35
3rd: 37
