The system x−6y=4, 3x−18y=4 has no solution. Change one constant or coefficient to make a new system with one solution.

Change one constant or coefficient to make a new system with an infinite number of solutions.

There are an infinite number of possibilities.  Here's one possible solution:

x-0y=4

3x-18y=4

Step-by-step explanation:

idk

step-by-step explanation:

i don't know

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
