Lesson 3 Problem-solving Practice Adding Linear Expressions 2. Heather was building a scale model of the Pentagon for her history class. 7" P= (246) 3. A mailing st mailing env a variety of 4 centimete Write and the perime (2x + 3) in a. Write and simplify an expression to represent the perimeter of Heather's scale model. 4. Find the perimete b. Find the perimeter of the model if x = 2: ​

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
