The sum of a number is P and seven is divided by 12.the result is three what is the number?

P = 29

Step-by-step explanation:

3 = P + 7

       12

Step 1: Multiply 12 on both sides; 12(3) = P + 7, or 36 = P + 7

Step 2: Subtract 7 on both sides; 29 = P

Solution: P = 29

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
