I need help with this equation:

12x+15=99

=7

Step-by-step explanation:

x=7

Step-by-step explanation:subtract 15 on both sides so 99-15 and then you write down 12x=84 then you dived 84 by 12 and then x=7 is ur answer

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
