Kareem cannot decide which of two washing machines to buy. The selling price of each is 660​$. The first is marked down by 40​%.
natka813 [3]

Answer:

See explanation

Step-by-step explanation:

The selling price is ​$495.

The first washing machine:

- is marked down by 30​%

$495 - 100%

$x - 100% - 30% = 70%

Find the value of x:

The second washing machine:

- is marked down by 20​% with an additional 10​% off

$495 - 100%

$y - 100% - 20% = 80%

Find y:

y=$495 . 0.8 = $396

Now,

$396 - 100%

$z - 100% - 10% = 90%

Find z:

z=$396.0.9  = $356.40  = $356

Thus, the sale price of the first washing machine is $347 and the sale price of the second washing machine is $356. The second machine is more expensive.

The line m has a slope of 2/3
Makovka662 [10]

Answer:

I think you need pictures but i'll try to help.

Step-by-step explanation:

What ever line is displayed in the answer that goes up 2 and over 3 on the graph is your answer.

Ex.

If you start with a graph at point 0,0 then go up 2 to point 2 on the y axis then over 3 to point 3 on the x axis. Draw a straight line between the first coordinate which was 0,0 and the second which would be 3,2 that line would have a slope of 2/3. then the next coordinate after 3,2 would also go up 2 and over 3 which would be point 6,4 and that coordinate would also fall on the thee same line as the previous 2 coordinates.
