Enter your answer and show all the steps that you use to solve this problem in the space provided. A.Solve a–9=20 B.Solve b–9&gt
Goryan [66]

Answer:

A) The value of a is <u>29</u>.

B) The value of b is <u>greater than 29</u>.

C) In both part A and part B we have used a common property  which is addition property and that we have add 9 on both side of equation in both parts.

D) The value of a in part A is equal to 29 whereas in part B the value of b is greater than 29.

Step-by-step explanation:

Solving for Part A.

Given,

a-9=20

We have to solve for a.

a-9=20

By using addition property of equality, we will add both side by 9;

a-9+9=20+9\\a=29

Hence the value of a is <u>29</u>.

Solving for Part B.

Given,

b-9>20

We have to solve for b.

b-9>20

By using addition property of inequality, we will add both side by 9;

b-9+9>20+9\\b>29

Hence the value of b is <u>greater than 29</u>.

Solving for Part C.

In both part A and part B we have used a common property  which is addition property and that we have add 9 on both side of equation in both parts.

Solving for Part D.

The value of a in part A is equal to 29 whereas in part B the value of b is greater than 29.
