Different points are used to identify the line, this can mean that both points lie on the same line.
Therefore the slope is the same because the line passes through both those points.
%change=100(final-initial)/initial
%change=100(25-40)/40=-37.5%
So Denise received a discount of 37.5% off the regular price.
Answer:
2 1/2 I think
Step-by-step explanation:
you find the L.C.M for all the fractions and multiply it. You should end up with whole numbers.
It should look like this
2n+3n=2
n= <u>2n+3n</u><u> </u> = <u>5</u>
2 2
n= 2 1/2
The pattern is multiplying the top by two and multiplying the bottom by 3.
16*2/81*3
32/243
64/729
128/2189
