Leon tried to solve an equation step by step. \qquad\begin{aligned} \dfrac12w-12&=18 \\ \dfrac12w&=30&\green{\text{ Step } 1} \\ w&=15&\blue{\text{Step } 2} \end{aligned} 2 1 w−12 2 1 w w =18 =30 =15 Step 1 Step 2 Find Leon's mistake. Choose 1 Choose 1

Explanation:

The given expression is :

The value of w can be solved as follows :

Add 12 to both sides,

Cross multiplying, we get :

Leon should have made mistake at last step where instead of multiplying 2 and 30 he divides 30 by 2 so that he get 15 as answer.

for e2020. the answer would be some directions from the mountain range so we can find mt. whitney. to locate which direction is north, you should use a   compass. this would not only find mt. whitney, but also becuase of this long paragraph you would get points because it's not like anyone actually reads your work becuase once they read the first sentence it sounds dumb enough to not read becuase i'm not good at answering this but the answer is compass for your benefit.
