Zack is taking a test in which he answers questions at a rate of 1/2 question per minute. How many questions can he
answer in 6 minutes?
3 12 6 4

well if he answers half a question per minute then it would take 2 minutes to answer a question. Therefore if you flip the numerator and the denominator you can multiply that by how many questions are being asked as shown:

q=6

1/2x2=1

2/1=2xq

2x6=12

?=12 minutes

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

answer is x<
