What are the steps for using integer tiles to evaluate the expression 45 divided by 15
a. start with 15 tiles and separate them into 3 same-sized groups.
b. start with 45 tiles and separate them into 15 same-sized groups.
c. assemble 45 groups of 3 tiles each.
d. assemble 45 groups of 15 tiles each.

 B.Start with 45 tiles and separate them into 15 same-sized groups.

Step-by-step explanation:

To evaluate 45 divided by 15 using integer tiles .

Here dividend = 45

Divisor =15

First we need to start with the dividend number, therefore we have to start with 45 tiles .

For the second step we need to separate them into same sized group and the size of the group must be same as the divisor.

Thus, we need to separate 45 tiles into 15 same-sized groups, we will get 3 groups which will be the answer.

Therefore, B is the right option.

the 4th choice is the correct one

step-by-step explanation:

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
