Step-by-step explanation:
Charge on atom is due to electron
Electron have negative charge while proton have positive charge and neutron have no charge. If there are 10 proton (10 positive charge)
2 is to 4 because 64/8 is 8. 4/2 is 2. 2 x 2 is in proportion to 8 x 8
Answer: D 2/3
Step-by-step explanation:
If the exterior angle is 120 degrees, you subtract 120 degrees from 360 degrees (the two angles form a circle) and get 240 degrees.
This is not a possible angle for a triangle because the angles in a triangle always add up to 180 degrees. Also, angles in triangles can’t be more than 180 degrees
Answer:
hey! This was the only part of mathematics I ever enjoyed! So consider this both of our lucky days: Answer is : (2,7)
Step-by-step explanation:
basically plug in Y to the first equation as sox + 4(-x + 9) = 30
x - 4x + 36 = 30- 3x = - 6
x = 2
then plug that in to Y!
Y = -(2) + 9
so Y = 7
and our answer is : (2,7)
