-2(2p – 4) = 3(p + 12)

Step-by-step explanation:

so you try to get p on one side

-2(2p-4)=3(p+12)

-4p+8=3p+36

8=7p+36

-28=7p

-4=p

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
