Does anyone knows how to solve this??!? If you do pls show me how to step by step
Solve the determinant of this 3x3 matrix

step-by-step explanation:

where is the questions

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

you could deduce the conclusion directly using the facts pertaining to the specific situation.

hope this .

i will u if u answer my question in math
