What you did on the first one is good...this is how you should do the rest of them.

2.) 36 ÷ x = 6
(first box)  36 - x - x - x - x - x - x
(second box)  this is going to be a tape with 6 groupings of 6 pieces
(third box)  x = 6

the object is for you to fully understand that the x = 6 can be used in the second box in place of the x to give the same answer as 6...

36 - 6 - 6 - 6 - 6 - 6 - 6 = 6
all division is meant to be is a quick way of subtracting.....

keep going..you are doing well.

If m = 5 and n = -2, evaluate 3m - 4n and n2 - m and find the product of the two expressions.
ddd [48]

Hence the correct answer is C) -23

Further explanation:

We have to put the values of m and n into both expression first separately and then multiply the answers.

Given expressions are:

Exp\ 1:3m-4n\\Exp\ 2: n^2-m

The values are:

m=5\\n=-2

Putting the values in expression 1:

3m-4n\\=3(5)-4(-2)\\=15+8\\=23

Putting the values of m and n in second expression

n^2-m\\=(-2)^2-5\\=4-5\\=-1

Multiplying both expressions:

(3m-4n)(n^2-m)=23* (-1)=-23

Hence the correct answer is C) -23
