35 <or= 20+4x

find x

15 < or = 4x

x=15/4

15/4 = 3.75

So You have to wrok 4 or greater hours for it to be cheaper for single fee

Since it is a quadrilateral, all sides equal 360 degrees

And opposite angles are congruent

So an equation can be used to model this

2x+2y=360

or x+y=180

System is a little funky, so after createing an account, you have to actually log in

Infinity can't really be defined. In a simple sense, It is all numbers

But it is more than that

It's not easily definable, because it goes on for ..... infinity(pun intended)

You can't say infinity goes to 999999999999999999999999999999 because any number you can create, Infinity will always not only more, but it will take your number, and make it a power and still be more that that

Resorting to spam ads on a math forum?

Wow, that is low

We can't really explain it unless you show us an example, as there could be a calc fraction problem such as:

\((\log{10}+sin{x})/cos{x}\)

Or is could just be a simple problem as not understanding how to solve them such as:

\(1/10*8/3\)

70% can be written as .7

so .7x is 70% of x

Substitute

.7(120) = 84

84

A treasure chest

Yo mama so ugly, she went to an ugly competition and they said "Sorry, no professionals"

She then went to a professional competition and they said "It wouldn't be fair to the other contestants if you partcipated"
