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.

b. 2

step-by-step explanation:

the slope of a line =δy/δx

δy= y₂-y₁

δx= x₂-x₁

therefore, using the points (-2,-3)   and (3,7) we can calculate gradient as follows:

m=(7--3)/(3--2) (a number minus a negative number the sign changes to a plus)

m=(7+10)/(3+2)

=10/5

=2
