Your friend says that in the number 45,951, one 5 is 10 times as great as the other 5. Is your friend correct? Expain.

No.

Step-by-step explanation:

The friend is not correct because in this case one five is 100 times greater than the other, not 10.

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

r and t.

both are 64 degrees.
