Answer:
the topmost one maybe?
Step-by-step explanation:
I'm guessing since X & Y are negative, (it's written X,Y,Z, right?)
The point would be reducing on the X&Y axes, an since Z is positive, it would increase on the Z axis
33/84
if you divide both top and bottom by 3 you will get your simplified answer:
11/28
-3x+20=2
move +20 to the other side
sign changes from +20 to -20
-3x+20-20= 2-20
-3x= 2-20
-3x= -18
divide both sides by -3
to get +x and x by itself
-3x/-3= -18/-3
Answer:
x= 6
To solve for the percentage increase of the cost of jacket, calculate first for the increase, divide it by the original price and then multiply by 100%. This is shown below.
% increase = ((98.60 - 85) / 85) x 100%
% increase = 16%
Thus, the price of the jacket increased by 16%.
