Answer:
a=1/2
Step-by-step explanation:
first we need to isolate a squared. so we add 1/4 to both sides
then you take the square root of a square to get 1/2
to check, 1/2 * 1/2 = 1/4
1/4-1/4 = 0
Since he sold it for $75 more,
% Mark Up = Mark Up/ Cost Price * 100%
% Mark Up = 75 / 125 * 100%
= 0.6 * 100% = 60%
Percent Mark Up = 60%.
Hope this explains it.
Answer:
A) 5x - 2y = 12
B) 3x + 2y = 36 Adding both equations eliminates "y"
8x = 48
x = 6 Putting x=6 into equation B we get
3*6 + 2y = 36
2y = 18
y = 9
