N is an integer.
write the values of n such that -15<3n6

Step-by-step explanation:

(Divide all sides by 3 to make it easier to understand)

Now you can just look at all of the possible values for n, knowing that it's an integer.

is less than , so we know that 's lowest value must be .

We also know that is less than or equal to , so the highest value of must be .

Now you can count through the remaining integers from to .

why can't you?

step-by-step explanation:

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
