Dave bought 3 pencils, 8 markers, and 5 pens. he wants to know how many items he bought in all. he added 3+5 first. what should dave add next?

Step-by-step explanation:

you never added any of the pencils,pens,or markers prices. If you can add that then I will answer

8 but you could add the first two and then add 8

Step-by-step explanation: Because  there are three numbers and you already took two out of the three its called process of elimination.

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

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
