Answer:

addition property of equality

multiplication property of equality

distributive property.

Step-by-step explanation:

We use addition property of equality , multiplication property of equality and distributive property.

We will not use reflexive property which is x  = x.

Let me show you an example.

solve the following equation:

2(x - 1) = 8

Use distributive property a(b - c) = a.b - a.c

2x - 2 = 8

Add 2 on both sides. Addition property of equality.

2x -2 + 2 = 8 + 2

2x = 10

Now multiply both sides by the reciprocal of 2, which is 1 over 2, we get

x = 5

Therefore, the answer is " addition property of equality , multiplication property of equality and distributive property."

Bernice sells 135 sea shells by the sea shore every day. She shells each sea shel for 3 dollars. For how many days does Bernice
horrorfan [7]

First we want to calculate exactly how much money Bernice sells on a daily basis, so we can determine how many days it'll take to earn 2,430 dollars. We can do this by multiplying the amount of shells she sells every day by the amount she sells them for. So 135 sea shells multiplied by 3 dollars.

<u>135 * 3</u>

This comes up to 405 dollars every day, quite a significant amount considering she's selling shells. Now, divide 2,430 dollars by 405 dollars. This will give us the final result.

<u>2,430 / 405</u>

It will take Bernice exactly 6 days to earn 2,430 dollars.

5y (- 9 - 3y) = 13 What is Y?
Murrr4er [49]
To solve this equation, we have to use the distributive property to multiply 5y through the parentheses. 

-45y - 15y^2 = 13

-15y^2 - 45y - 13 = 0 

15y^2-45y-13=0
