You would estimate to 4800 and 10 then you would take 4800 divided by ten which is 480
that's the way I'd do it hope this helps
Newton's law of gravitation says that the force due to gravitation between two objects with masses m₁ and m₁ is given by the formula
Where r is the distance between the objects, and G is the gravitational constant (about 6.674×10⁻¹¹ m³⋅kg⁻¹⋅s⁻²)

Answer:
- 57 = (7/8)x -13
- $80
Step-by-step explanation:
1. I find it convenient to use variable names that remind me what they stand for. Here, we can use "j" to represent Joanne's earnings, and "e" to represent Erin's earnings.
j = 57 . . . . . Joanne earned $57
j = (7/8)e -13 . . . . . Joanne's earnings were $13 less than 7/8 of Erin's
Substituting for j, we get one equation for Erin's earnings
57 = (7/8)e -13
Using 'x' for Erin's earnings, this is ...
57 = (7/8)x -13
__
2. We can solve the equation as follows:
70 = 7/8x . . . . . . add 13
80 = x . . . . . . . . . multiply by 8/7
Erin earned $80 in tips.
