Javier has a job installing windows. he earns a rate of $75 per day plus $8 per window installed. he also receives a stipend of $25 for snacks. javier knows his weekly earnings can be shown with the following expression:
75d + 8w + 25
part a: identify a coefficient, a variable, and a constant in this expression.
part b: if javier works for 5 days and installs 48 windows, how much does he earn? show your work to receive full credit.
part c: if javier gets an increase in his stipend and receives $40 for snacks, would the coefficient, variable, or constant in the equation change? why?

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
