Answer:

Is there a typo in this page of work? It should be $225 more... But this isn't an option... I'm not sure... Is it possible to contact a teacher?

Step-by-step explanation:

7/10 of $450 is $315

Online price: $315

6/5 of $450 is $540

Other department store: $540

$540-$315=$225

This doesn't make sense at all... sorry...

If a+b+c=a*b*c then how many real number solutions are possible
nikklg [1K]

Answer:

6 solutions.

Step-by-step explanation:

1 + 2 + 3 = 6,

1*2*3 = 6.

So a = 1, b = 2 and c = 3 will fit this identity, as would any other combination of the 3 values. That is a total of 6 possible solutions. It is 6 because there are 6 possible different arrangements of 1,2 and 3.

As a matter of interest, 6 is one of  the set of 'perfect numbers' where the sum of all the factors equals their product.  The next one is 28 but that has 5 factors so that would not fit.

What’s the slope of a line perpendicular to a line through points, <br> E(5,7), F(3,1)
juin [17]

Answer:

-1/3 is the slope perpendicular

Step-by-step explanation:

When we have 2 points, we can use the formula

m = (y2-y1)/(x2-x1) to find the slope

m = (1-7)/(3-5)

   =-6/-2

    =3

The slope is 3

We want a slope perpendicular

Remember that is the negative reciprocal

- (1/3)

-1/3
