Because the greater the denominator, the smaller the number is.
1/6 = .166666667
1/8 = .125
and 1/3 = .333333333333333333
Multiply all with 5 to get rid of fraction.
5( 4/5x + 5 ) < 5(-3)
5(4/5x) + 25 < -15
4x + 25 < -15
Separate x
4x < -15 -25
4x < -40
x < - 10
:D
I think you divide 18.96 by 3 to get the amount for one pound cost then go pound for pound there
-8x+9y=23 -- y=8/9x+23/9
(-4,-1), (1/2,3)
(3--1)/(1/2--4)= 4/(4 1/2)=.888888889
So answer A because if you rearrange it in y=mx+b form you see it's y=8/9x+23/9. And using the two points provided you can subtract to find the slope which comes out to be 8/9 the only two answers with that are A and B, so eliminate C and D. Then you can easily tell by looking at the graph that the y-intercept is positive, thus answer A is the only answer that works.
Think of integers that have a sum (addition) of 8 that don't include negative integers.
4+4=8
6+2=8
5+3=8
Pat is right there are three different pairs of integers that can have a sum of 8.
