78 is 15% of what #?

nirvana33 [79]

1. 78 = 0.15x
78 / 0.15 = x
520 = x.....so 78 is 15% of 520

2. | 3x - 2 | = 8 | x + 1 | = 1

3x - 2 = 8 -(3x - 2) = 8 x + 1 = 1 -(x + 1) = 1
3x = 8 + 2 -3x + 2 = 8 x = 1 - 1 -x - 1 = 1
3x = 10 -3x = 6 x = 0 -x = 2
x = 10/3 x = -2 x = -2

ur answer is : x = -2

3. 3y - 4x + 5 = 0
