(D) 6
Step-by-step explanation:
We can substitute the values of a (7) and b (-4) into the equation to find it's result.
![\frac{|2a| -b}{3} \\\\\\\frac{|2\cdot7|-(-4)}{3}\\\\\frac{|14|+4}{3}\\\\\frac{14+4}{3}\\\\\frac{18}{3}\\\\ 6](https://tex.z-dn.net/?f=%5Cfrac%7B%7C2a%7C%20-b%7D%7B3%7D%20%5C%5C%5C%5C%5C%5C%5Cfrac%7B%7C2%5Ccdot7%7C-%28-4%29%7D%7B3%7D%5C%5C%5C%5C%5Cfrac%7B%7C14%7C%2B4%7D%7B3%7D%5C%5C%5C%5C%5Cfrac%7B14%2B4%7D%7B3%7D%5C%5C%5C%5C%5Cfrac%7B18%7D%7B3%7D%5C%5C%5C%5C%206)
So 6 is the value of this expression when a is 7 and b is -4.
