Move the 4x over to the left side and get:
6x - 3 = 9
Then move the 3 over to the right....
6x = 12
Divide by 6
x = 2
Answer:
you multiply 300 by 5 % and that gives you 15
Step-by-step explanation:
240(.15) = 36
240 - 36 = 204
Lucy has 204 miles left to drive.
Given:
r = 3.8x10⁵ km = 3.8x10⁸ m, the distance between the earth and moon,
F = 20.46x10²⁵ N, the gravitational force between the earth and the moon,
G = 6.674x10⁻¹¹ m³/(kg-s²), gravitational constant
M = 5.972x10²⁴ kg, the mass of the earth.
Let m = mass of the moon.
Then
F = (G*M*m)/r^2
or
m = (F*r^2)/(G*M)
In SI units,
m = [20.46×10²⁵ * (3.8×10⁸)²]/[6.674×10⁻¹¹ * 5.972×10²⁴]
= 7.4125×10²⁸ kg
Answer: 7.4125x10²⁸ kg
