What is commutative property of addition?

The commutative property states that an expression of the form (A + B) can be solved as (B + A) by an addition operation that does not change the end result.

The commutative property of addition says that it doesn't matter how we add two numbers, the result of the addition would be same.

For two numbers x and y, we have: x + y = y + x

Thus, if we take 3 numbers as a,b and c;

a + b + c = b + a + c = b + c + a = a + c + b = c + a + b = c + b + a

We have been given an expression;

when you divide decimals, the number that goes outside needs to be a whole number so it has to be 8
since you moved the decimal you also have to move the decimal from the inside. If you move the decimal it is going to be 4.4

Solve the system. y = -x + 3 and y = 2x
the solution is (__,__).
Explain your choice of method.

Answers

Answer: (1, 2)

which means

x = 1

y = 2

Step-by-step explanation:

y = -x + 3

y = 2x

Because both equations are set equal to y, they can be set equal to each other. The equations are ready to go to use Substitution method.

Substitute.

-x + 3 = 2x

Add x to both sides.

3 = 3x

Divide by 3.

3/3 = x

1 = x

We can put the 1 in for x in either equation.

y = 2x

y = 2(1)

y = 2

Putting x for 1 into the other equation is a good check.

y = -x + 3

y = -1 + 3

y = 2

So the x and y that work in both of these equations is:

x = 1 and y = 2

The form that was asked for was ( , ).

So the answer is

(1, 2).

The circumference talks about the outside of the circle. So the formula for the circumference of a circle is 2πr (r stands for radius and π is pi. In this case we use 3.14 for pi).

Since the radius is half of the diameter and we know that the diameter of the trashball is 4 in, we half the 4. So the radius of the trashball is 2 in.

Now plug everything in the formula.

2(3.14)(2) = 12.56.

Ava bought snacks for her team's practice. She bought a bag of oranges for $2.71 and a 4-pack of juice bottles. The total cost before tax was $6.75. Write and solve an equation which can be used to determine jj, how much each bottle of juice cost.

Answers

Answer: Let j be the cost of each juice bottle.

The total cost of the juice bottles is 4j. The total cost of the oranges and juice bottles is $6.75.

Thus, the equation that represents the given information is: 4j + $2.71 = $6.75. Subtract $2.71 from both sides to get: 4j = $4.04. Divide both sides by 4 to get: j = $1.01.

Therefore, each juice bottle costs $1.01.

Step-by-step explanation:

Total cost = cost of a bag of oranges + cost of 4-pack juice bottles

$6.75=  $2.71 + (4 x jj)

$6.75 = $2.71 + 4jj

take similar terms: $6.75 - $2.71 = 4jj

Add similar terms: $4.04 = 4jj

Divide both sides of the equation by 4: jj =  $4.04 / 4=

jj = $1.01
