Answer:
J.J.Thomson was the scientist who discovered electrons. He discovered the electrons from the cathode ray experiment
Step-by-step explanation:
x = 7
3*x-6-(15)=0
3x - 21 = 3 • (x - 7)
Solve : 3 = 0
Solve : x-7 = 0
Add 7 to both sides of the equation :
x = 7
Answer:
X = 38.7°
Step-by-step explanation:
Reference angle = x
Opposite side length = 8 cm
Adjacent side length = 10 cm
Applying trigonometric ratio formula, we have:


x = 38.7° (to the nearest tenth)
2x+4=24
-4 -4
-------------
2x=20
÷2 ÷2
----------
X=10
So 10 stickers in each pack
