If 3x > or = 2x+5 then what is 3x-10 > or = 2x -__

To save time, you dont need to write "> or ="

You can simply write ">=" without the quotes.

So 3x >= 10 means "3x is greater than or equal to 10"

we start with 3x >= 2x+5

we want 3x-10 on the left hand side. We already have a 3x. So if we stick a -10 on the left side, we need to do the same thing to the right side to balance things out. We can subtract 10 from both sides to do this

3x >= 2x+5

3x-10 >= 2x+5-10 ... subtract 10 from both sides

3x-10 >= 2x-5

So it looks like a 5 will go in the blank because the negative portion is already taken care of.

it costs $20 to interview each person for a survey. find the cost to obtain a +- 3% margin of error.

step-by-step explanation:

copy and paste, put it in google

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
