How my supposed to divide two and 312 to the estimate quotient

Round

Step-by-step explanation:

312÷2=154

Round DOWN to 150. That's how you estimate. Round it to the nearest 10. (In this case)

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

55% are girls and 45% are boys : ) hope this
