Answer:
the answer to that is 10(N+14)=9N
6x - 15 = 75 (Third Equation)
6x = 90
x = 15 ✅
x + (x - 10) = 26 (Fourth Equation)
x + x - 10 = 26
2x - 10 = 26
2x = 36
x = 18 ✅
5x - 3x = 10 (First equation)
2x = 10
x = 5 ✅
2(2x - 1) = 46 (Second equation)
4x - 2 = 46
4x = 48
x = 12✅
The amount of matter an object has is called it's mass.
Mass does not depend on gravity, so the mass ALWAYS stays the same.
First find the increase in books
144-76 = 68
Next find the percentage for 68
68/144 = 0.47222
0.47*100 = 47%
