Answer:
4925cm^2
Step-by-step explanation:
whole thing - small thing = shaded
small = 25 x 25 = 625
whole thing = a+b / 2 x h     =    111+111/2 x 50 = 5550
5550-625= 4925cm^2
 
        
             
        
        
        
The equation of the line written in slope-intercept form is:

Where m is the slope and b is the y-intercept.
You find the slope using the formula:

Where point A coordinates' are (-4,-19) and point B (-6, 4).


Now you find b (y-intercept) substituting in y=-23/2x+b the coordinates of point A or point B:
(I'll use point B coordinates')
y=-23/2x+b
4=-23/2×(-6)+b
4=46+b
b=-42
The equation of the line is y=-23/2x-42
 
        
        
        
100 people cuz 90% of 100 is 90 
5 % is 5
So its easier to interpret

Answer:4
Step-by-step explanation:
First distributive 1.5 to x+4 and 4.5 to x-2. You get 1.5x+6-3 = 4.5x-9. Next you need to move all the variable terms to one side. You can do either, it doesn't matter, but I subtracted 1.5 x to each side of the equation. You get left with 6-3 = 3x-9. Solve 6-3 and you get 3=3x-9. You 9 to both sides of the equation. You get 12=3x. You divide by 3 on both sides and get 4=x/x=4.
