25*

Step-by-step explanation:

all angles in a triangle will equal 180*

180-135=45

the two anlges with x need to = 45 \

the number thst works for that is 5          4times5=20 and 5times5=25 togather they = 45  

so "x" equals 5   therefore making <a 25*

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
