Yis equal to 12 times the difference between a number and 4. which of the following equations models this situation?

n - a number

"×" times

"-" difference

y = 12 × (n - 4) → y = 12(n - 4)

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

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2
