Answer:
Mean Absolute Deveation (MAD): 13
Step-by-step explanation:
.
Step 1: Simplify both sides of the equation.
−23(3x−4)+3x=56
(−23)(3x)+(−23)(−4)+3x=56(Distribute)
−69x+92+3x=56
(−69x+3x)+(92)=56(Combine Like Terms)
−66x+92=56
−66x+92=56
Step 2: Subtract 92 from both sides.
−66x+92−92=56−92
−66x=−36
Step 3: Divide both sides by -66.
−66x /-66= -36/-66
x= 6/11
