1. 3

2. -2.5+3= .5

3. <>

-5 -4 -3 -2 -1 0 1 2 3 4 5

^ ^ ^

Step-by-step explanation:

When you add 3 to -2.5, the result is a positive .5. I wasn't sure what the number line meant, so I did my best

-1/2 +2

step-by-step explanation:

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
