Mrs katie constructs a cube with 512 magnetic block students and her two classes will each make an identical cube. there are 28 students in one class and 25 students in the other class. how many blocks dies she need got all her students?

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.

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
