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> 20 c. how is solving the equation in part a similar to solving the inequality in part b? d. how are the solutions different?

A) The value of a is 29.

B) The value of b is greater than 29.

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,

We have to solve for a.

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

Hence the value of a is 29.

Solving for Part B.

Given,

We have to solve for b.

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

Hence the value of b is greater than 29.

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.

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
