Arc MN is 100 degrees because it is the double of 50 degrees.
12x+4=100
12x-4=100-4
12x=96
x/12=96/12
x=8
Answer:
5
Step-by-step explanation:
o+5=y=5
1+5=y=6
2+5=y=7
.:y=x+5
Lets day the original price of the dvd player was $100,
36% marked down means you pay $64x
64x = $41.60
100x = 100/54 x 41.60 = 4160/64 = #65.00 = original cost
similarly, stereo tuners = 100/78 x 69.42 = 6942/78 = $89 original cost
DVD = 65- 41.60 = $ 23. 40 less
Stereo = 89- 69.42 = $ 19.58 less
Diffrence is $ 3.82
so your answer is the dvd player price was reduced by $3.82 more than the stereo tuner.
