Mr. Hall has $230 to spend on supplies for his classroom. He will buy a bookshelf and some books. The bookshelf costs $90. He will buy books that cost $5 each. Create an inequality to model this problem then solve the inequality. What does your answer mean?

Make sure to show or explain how you got your answer.

He can buy 28 books or less.

Step-by-step explanation:

ox will represent the number of books he can buy. He can only use $230 or less. I am going to use <, but It's supposed to be less than or equal, not less than, so make sure to put a less-than sign with a line under it.

90+5x<230          Subtract 90.

5x<140               Divide by 5.

x<28                    This means that he can buy 28 or fewer/less books.

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
