Step-by-step explanation:
Since the concert promoter started with 2  pages of ads but had to cancel 1
 pages of ads but had to cancel 1  , subtracting the cancelled amount from the original amount will give the amount of advertising space the promoter is now actually using:

In order to subtract fractions, you need to have like denominators, so you need to convert  into an equivalent fraction with a denominator of '8'.  Since 4 x 2 = 8, then you also need to multiply the numerator by the same factor: 3 x 2 = 6.

Answer:
Altitude of Equilateral Triangle h = (1/2) * √3 * a. Angles of Equilateral Triangle: A = B = C = 60° Sides of Equilateral Triangle: a = b = c.
Hope this helped!

Answer:
Step-by-step explanation:
Given that 
Slope m=-3 
A point (x, y)=(4,-2)
Equation of a line can generally be written as 
y=mx+c
Where, m is the slope 
And c is the intercept on y-axis
Since we are given m=-3
Then, y=mx+c becomes
y=-3x+c
To get c, let substitute the point given, i.e x=4 and y=-2
y=-3x+c
-2=-3(4)+c
-2=-12+c
-2+12=c
c=-2+12
c=10
y=mx+c, then m=-3 and c=10
Then, the equation the line becomes y = -3x + 10
This is the required line equation 
 
        
             
        
        
        
You have a system of equations 

. 
1. Substitude right side of second equation into the left side of the first equation: 

.
