Answer:
n = 13
Step-by-step explanation:
20= -6+2n
Add 6 to each side
20+6= -6+6+2n
26 = 2n
Divide each side by 2
26/2 = 2n/2
13 =n
Step-by-step explanation:
the slope of a line or linear equation is always the factor of the driving variable.
usually in the form of
y = ax + b
x is the variable, and a the slope.
but in our case the variable is called "n".
it does not matter, the same principle applies.
the slope is the factor of n : 1050.
and as the slope is always the ratio y/x, we are looking for a fraction form, and that would be 1050/1.
so, the third answer is correct.
Step-by-step explanation:
This an answer see in picture
earrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
p*x+57-(-75*x+q)=0
In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.
Unless there is none then in that case there very well may be infinite solutions
