Question 129753
Just so we understand each other right off the bat, I'm not going to do your entire homework assignment for you.  I'll show you how to do a couple of these and you should be able to apply the same techniques to solve the rest of them.


#4:  3 consecutive odd integers.  Let x be the first one, then the next one is x + 2, and the third one is x + 4.  The largest plus two times the smallest is 25, so:


{{{(x+4)+2x=25}}}
{{{3x+4=25}}}
{{{3x=21}}}
{{{x=7}}}


So your odd integers are 7, 9, and 11.

Check:  11 + 14 = 25.


#6.Separate 846 into 3 parts so that the second part is twice the first part and the third part is triple the second part.


Let the first part be x.  Then the second part has to be 2x, and the third part has to be 3(2x), or 6x.  And the three parts add up to 846.


{{{x + 2x + 6x = 846}}}
{{{9x=846}}}
{{{x=94}}}

So the three parts are 94, 188, and 564


Now it's your turn.
