Let's make an equation. x+y=46; x is the smaller even numbe and y is the bigger even number. To solve, we need just one variable. Since y is two bigger than x, we can make another equation. x+2=y; we can plug this into the first equation. x+x+2=46; add like terms. 2x+2=46; now subtract 2. 2x=44; now divide by 2. 44÷2=22; this is the smaller number, all we have to do is add 2 to find the other.
We can get the 5 fractions by multiplying 8/5 by 2, 3, 4, 5, and 6. 8/5*2=16/5 8/5*3=24/5 8/5*4=32/5 8/5*5=40/5 or 8. 8/5*6=48/5. Hope this helps! -Raiden
The inequality should be The sign on the right is only a 'smaller than' sign because he spent less than 180. On the left, assuming that even if Calvin took nobody (poor Calvin), we should assume that he at least went himself, hence he spent a minimum of $12.
