Answer:

We see adding mixed number is easier by using the Commutative and Associative Properties of Addition.

Step-by-step explanation:

We have to show  how the Commutative and Associative Properties of Addition can make adding mixed numbers easier.

For given numbers a , b and c , we have,

Commutative property of addition:

a+b=b+a

Associative property of addition,

a+(b+c)=(a+b)+c

Let us show it by using example,

Consider the addition of numbers having fractions,

\frac{2}{3}+(2+\frac{4}{3})

it is easy to find the sum by first combining fraction term and then adding 2 to it.

We first apply commutative property,

\frac{2}{3}+(2+\frac{4}{3})=\frac{2}{3}+(\frac{4}{3}+2)

Now we apply associative property,

\frac{2}{3}+(\frac{4}{3}+2)=(\frac{2}{3}+\frac{4}{3})+2

On solving , we get,

(\frac{2}{3}+\frac{4}{3})+2=\frac{2+4}{3}+2=\frac{6}{3}+2

Solving we get,

\frac{6}{3}+2=2+2=4

We see adding mixed number is easier by using the Commutative and Associative Properties of Addition.

The length of Rebecca’s rectangular garden was two times the width “w”. She increased the length and width of the garden so that
Damm [24]

Answer:

rebecca increased the length by 3 and the width by 2

Step-by-step explanation:

First we need to find the length and width by factorizing the expressio ofr the area;

A = 2w^2+7w+6

A = 2w^2+4w+3w+6

A = 2w(w+2)+3(w+2)

A = (2w+3)(w+2)

Since l = 2w

Length = 2w+3

width = w+2

This shows that rebecca increased the length by 3 and the width by 2

If the delivery company achieves its improvement goal, by how much will the hourly delivery rate of the typical delivery staff m
DanielleElmas [232]

It should be noted that the hourly delivery rate is calculated by dividing the income made by the number of hours worked.

<h3>How to calculate the hourly delivery rate</h3>

Your information is incomplete. Therefore, an overview of the information will be given.

In order to get an hourly rate, it's important to divide the income that the person gets by the number of hours that the person worked.

In this case, let's say that the income is $20000 and the number of hours that was worked monthly was 240 hours, the hourly rate will be:

= $2000/240

= $8.33 per hour
