The following sets of numbers are possible side lengths of a triangle. which of the following sets forms a pythagorean triple?

a. 18, 24, 42
b. 45, 28, 53
c. 15, 30, 45
d. 33, 77, 22

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
