Sydney read 50 pages in 40 minutes. She reads at a constant rate. How many pages can Sydney read per minute?

1.25 words per minute

Step-by-step explanation:

Divide 40 by 40 to get 1 minute

Divide 50 by 40 to get 1.25 words

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
