explanation.7x+9forx=6

7×6+9=51

51

Step-by-step explanation:

if x is equal to 6 then your answer is 7 (6) + 9 or 42+9 which equals 51.

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
