57% people ordered steak. 120 did not. how many customers were there that night?
jok3333 [9.3K]
X - number of customers

120+57\%x=x\\&#10;120+0.57x=x\\&#10;0.43x=120\\&#10;x\approx297.07

There can't be a fraction of the number of people, so there must be some mistake in the question.

Can someone please explain to me how to find the value of m? thanks<br>-10 = -10 + 7m
GarryVolchara [31]
                                        -10  =  -10  +  7m

Add  10  to each side:      0  =          7m

Divide each side by  7 :    0  =          m


Please take a second and just LOOK at the equation you started with.
It says: 

--  You have this number '-10' . 

--  Your number  -10  is going to be exactly the same size
     after you add 7 of something to it.

The ONLY way that could happen is if the 'something' is 'nothing' .

       ' m '  must be nothing.
