B. the ending elevation
C. the elevation halfway through their hike

3. What is their starting elevation?

2. A

3. 450-290=160

Step-by-step explanation:

1. x+290 2. A 3. 290 because 290+290=450

Step-by-step explanation:

a negative exponent is translated as follows:

so, we have

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
