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."

Given the venn diagram, find P(brother and sister)
LUCKY_DIMON [66]

Based on the venn diagram of siblings, the probability of having a brother and sister is c. 0.33.

<h3>What is the probability of brother and sister?</h3>

The probability of having a brother and sister can be found as:

= Number of those with brother and sister / Total number of people in poll

Solving gives:

= 10 / (8 + 10 + 5 + 7)

= 10 / 30

= 0.33

In conclusion, the probability of having a brother and sister is 0.33.
