one large papaya weighed 5 kg if 20 children shared it by cutting into pieces , how much would each piece weight?

0.25 kg

Step-by-step explanation:

This is a division problem, assuming the papaya is cut evenly.

[Divide]

5 kg / 20 children = 0.25 kg

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
