Answer:

Step-by-step explanation:

1) 6r - 12 + 6r + 11 = 11

Combine like terms

6r + 6r - 12 + 11 = 11

12r - 1 = 11

12r = 11 + 1

12r = 12

r =12/12

r = 1

2) 8m + 5 + 13m - 5 = 42

8m + 13m + 5 - 5 = 42

21m +0 = 42

21m = 42

m = 42/21

m = 2

3) 4x + 5 + 5x + 6 = 29

4x + 5x + 5 + 6 = 29

9x + 11 = 29

9x = 29 - 11

9x = 18

x = 18/9

x = 2

Why might you want to use the commutative property to change the order of the integers in the following sum before adding

Delicious77 [7]

Commutative Property is the property in which you can move around numbers in numerical operations like, addition and multiplication while retaining their result. In contrast to subtraction and division in which position is an important factor for every result, here it is regardless. Why might you want to use this property?Well, most importantly it suits the operation of addition and hence, to ensure the arrangement of the number is in symmetric proportion to its counterpart such as 3 + 2=2 + 3. Or rather, understanding that the equations in both sides are but the same and equal in sum. Thus, this is much more usable or will make more sense if used in a larger scale of complex equations and integers.

3 1/2 boxes of tomatoes currently. uses 1 3/4, taking it away basically.

3 1/2 - 1 3/4

3 2/4 - 1 3/4 ;; i did this with finding a common denominator for it to be easier for me to solve.

3 - 1 = 2

2/4 - 3/4 = -1/4

2 + -1/4 = 1 3/4

correct me if wrong.

A presidential candidate plans to begin her campaign by visiting the capitals in 44 of 5050 states. what is the probability that

defon

Part A:

Given that A presidential candidate plans to begin her campaign by visiting the capitals in 4 of 50 states.

The number of ways of selecting the route of 4 specific capitals is given by

$^{50}P_4= \frac{50!}{(50-4)!} = \frac{50!}{46!} =50\times49\times48\times47=5,527,200$

Therefore, the probability that she selects the route of four specific capitals is $\frac{1}{5,527,200}$

Part B:

The number of ways of selecting the route of 4 specific capitals is 5,527,200.

Since the number of ways of selecting the route of 4 specific capitals is too large it is not practical to list all of the different possible routes in order to select the one that is best.

Therefore, "No, it is not practical to list all of the different possible routes because the number of possible permutations is very large."
