Illustrates the commutative property of multiplication.
VLD [36.1K]

For example a × b × c = c × a × b

Answer:

Therefore the Commutative Expression is,

11 × w × 3 = 11 × 3 × w

Step-by-step explanation:

Commutative property:

The Commutative property states that order does not matter.

This property allows Two or more factors to be multiplied in any order without Changing the product.

Multiplication and addition are commutative.

For example a × b = b × a

1. 2 × 5 = 5 × 2  

Therefore the Commutative Expression is,

11 × w × 3 = 11 × 3 × w

Brock heard that as a general rule, he should spend no more than one week's pay on rent. If Brock's salary is $25,200 per year,
olasank [31]
There are about 52 weeks in a year, so divide 25200 by 52 (484.6). He gets paid $484.60 per week. So he should spend a maximum of C. $485 on rent per month.

21 Maria sold small boxes of candy for $1 and
Anna35 [415]

Answer:

There where 10 <u>more</u> Small boxes sold than Large boxes.

Step-by-step explanation:

<u>This is a typical question that can be solved by obtaining a system of two linear equations and solving for each variable. </u>

In principle Linear Equations are algebraic expressions denoting a relationship between a Dependent variable y and an Independent variable x. In a system of Two Linear equations we have<u> two equations</u> of the same variable sets (thus Two Independent variables) so in this case both y and x will be variable terms.

Now with respect to the question and the given information, here our two Variable terms will be the small and the large boxes.

<u>Given Information:</u>

  • Small Boxes (lets call them s) cost $1 per box
  • Large Boxes (lets call them l) cost $4 per box
  • Total Number of Boxes sold is 30
  • Total Profit from sold Boxes is $60

Thus from the above we can obtain one equation denoting the Total Number of Boxes sold and one equation denoting the Total Profit from sold boxes, respectively, as follow:

s+l=30        Eqn(1): Total Number of Boxes

1s+4l=60     Eqn(2): Total Profit from sold boxes

Now we have a system of two linear equations which we can solve and find the number of small and large boxes, s and l respectively.

From Eqn(1) we see that

s=30-l      Eqn(3).

Plugging Eqn(3) in Eqn(2) we can solve for l as:

1(30-l)+4l=60

30-l+4l=60       Factored out bracket

3l=60-30          Gather similar terms on each side and simplify

3l=30

l=\frac{30}{3}

l=10

Plugging in the value for l=10 in Eqn(3) we have

s=30-10\\s=20

So we know that they were<u> 10 Large Boxes and 20 Small Boxes sold</u>, thus to answer our question, there where 10 more Small boxes sold than Large boxes.
