The commutative propertyof addition says, "that you will get the same answer whether you are adding 1+2 or 2+1. this also works for 2 or more number."

I hope this helps!

Commutative property states that in addition and multiplication changing the order of operands does not change the result.  Division and subtraction are not commutative.

We will see commutative property of addition by example. Let us take any two numbers like 5 and 3. Now let us add these numbers.

5+3=8

Now we will add these number by switching their order.  

3+5=8

We can see that changing order of our numbers has not affected our answer. We got 8 by either way.

5+3=3+8

Now we will see commutative property of multiplication. We will take the same numbers and multiply them.

5\times3=15

Now let us change order of our numbers.

3\times5=15

We have seen from our above examples that order doesn't matter in addition and multiplication of numbers, therefore, addition and multiplication of numbers are commutative operations.

Now let us see if this true for division and subtraction.

4-2=2

2-4=-2

We can see that 2\neq-2. As order matters in subtracting numbers, therefore, subtraction of numbers is not a commutative operation.

Now let us see an example if division is commutative or not.

\frac{4}{2} =2

\frac{2}{4} =\frac{1}{2}

We can see that 2\neq\frac{1}{2}. As order matters in multiplying numbers, therefore, multiplication of numbers is not a commutative operation.

Boating: A paddleboat moves at a rate of 12 mph in still water. If the rover’s current moves at a rate of 3 mph, how long will i
Lostsunrise [7]

The time taken by the boat to travel 32 miles downstream is 2.1 hours and for upstream 3.56 hours.

<h3>What is speed?</h3>

Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance.

Given that:-

  • A paddleboat moves at a rate of 12 mph in still water. If the rover’s current moves at a rate of 3 mph.
  • how long will it take the boat to travel 36 miles downstream and 36 miles upstream?

The time taken by the boat upstream will be calculated as:-

( B + W ) Td = D

( 12 + 3 ) Td = 32

( 15 ) Td = 32

Td = 32 / 15 = 2.1 hours

The time taken by the boat downstream will be calculated as:-

( B - W ) Tu = D

( 12 - 3 ) Tu = 32

9 Tu = 32

Tu = 32 / 9 = 3.56 hours.

Therefore the time taken by the boat to travel 32 miles downstream is 2.1 hours and for upstream 3.56 hours.

Write a list of 6 ordered pairs to show the height of the candle in inches (y) as a function of time in hours (x) from the first
Bumek [7]

A function assigns the values. The list of 6 ordered pairs to show the height of the candle inches are (1,8.5), (1,8), (1,7.5), (1,7), (1,6.5), and (1,6).

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

The rate at which the candle burns down is 0.5 inches per hour. Now, if we substitute the value of the point (0,9) in the function of a line, and the rate as well, we will get,

y = mx +c

9 = -0.5(0) + c

c = 9

Now, the equation that can represent the height of the candle at any hour after it is lit will be,

y= -0.5x+9

substitute the value of x as 1, 2, 3, 4, 5, and 6 to get the value of y and form ordered pairs.

  • y=-0.5(1)+9 = 8.5 inches  ⇒ (1,8.5)
  • y=-0.5(2)+9 = 8 inches  ⇒ (1,8)
  • y=-0.5(3)+9 = 7.5 inches  ⇒ (1,7.5)
  • y=-0.5(4)+9 = 7 inches  ⇒ (1,7)
  • y=-0.5(5)+9 = 6.5 inches  ⇒ (1,6.5)
  • y=-0.5(6)+9 = 6 inches  ⇒ (1,6)

Hence, the list of 6 ordered pairs to show the height of the candle inches are (1,8.5), (1,8), (1,7.5), (1,7), (1,6.5), and (1,6).
