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
3y = 4x - 5
y = 4/3x - 5/3
slope = 4/3
Integers involve with negative, so D isn't the correct answer the correct answer will be A.
8) C
9) A
10) B
11) C
Hope i could help
(-3 1/3) / (4/9).....turn -3 1/3 to an improper fraction
(-10/3) / (4/9)...when dividing fractions, flip what u r dividing by, then multiply
-10/3 * 9/4 ...now just multiply
-30/4 or if u need it back as a mixed fraction, it is - 7 1/2
