Answer:
R = 8,228,571.43 (Approx)
Step-by-step explanation:
Given:
R = x²/y
x = 4.8 x 10⁵
y = 2.8 x 10⁴
Find:
Value of R
Computation:
R = x²/y
R = (4.8 x 10⁵)²/ (2.8 x 10⁴)
R = 23.04 x 10¹⁰ / (2.8 x 10⁴)
R = 8.22857.. x 10⁶
R = 8,228,571.43 (Approx)
(-8) - 3y= 25
-8-3y= 25
move -8 to the other side
sign changes from -8 to +8
-8+8-3y=25+8
-3y= 33
divide both sides by -3 to get y by itself
and to get +y
-3y/-3= 33/-3
Answer:
y= -11
Step-by-step explanation:

If they have the same charge
x+x+x+x+x+x+x=-42
7x=-42
x=-6
so to check our answer
-6-6-6-6-6-6-6=-42
-12-12-12-6=-42
-24-18=-42
-42=-42
