The store clerk has 21 mugs to display on shelves. she wants to display an equal number of mugs on each shelf with no mugs left over. which problem below shows a way she can do this?

The concept to do this question is to break the number into its factors and then make different combination.

The given number has just two factors

The factors of 21 are 3 & 7.

Which means

21 = 3 × 7.

So

Either we can have 7 shelves with 3 mugs on each shelf.

Or

We can have 3 shelves with 7 mugs on each shelf.

This way as 21 is divisible by 3 & 7. No mugs shall be left out.

So We have two solutions to this.

7 shelves with 3 mugs on each shelf.

3 shelves with 7 mugs on each shelf.

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
