Tatiana had 350 dollars she spent 180 dollars on herself and the rest on her presents for her family write an equation to express how much tatiana spent on her family

350 - 180 = x

Step-by-step explanation:

Because 180 has been spent, this can be subtracted from 350 which is the equation:

350 - 180 = x

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
