Question 211142
1)twice the sum of a number and eleven is twenty-two less than three times the nmber. find the number.
2n + 11 = 3n - 22
n = 33
-------
2)the sum of three consecutive even integers is 66 find the integers.
Do these the easy way.
66/3 = 22, that's the middle number.
--> 20, 22, 24
------------
3) the perimeter of a triangle is 96 in. The lengths of the sides are represented by consecutive integars. find the measures of the sides.
Same thing as above.
96/3 = 32
Sides = 31, 32, 33
------------------
4)the sum of three consecutive odd integars is 89 more than twice the largest integar. find the integars. 
n = middle integer
n-4 + n-2 + n = 2n + 89
3n-6 = 2n+89
n = 95
--> 91, 93, 95
-----
PS, it's integer, no a.
