Marlow is comparing the prices of two trucks rental compaines company a charges $3 per hour and an addtional $75 as serivce charges company b charges $2 per hour and an additional $85 as serivce charges

company a charges $3 per hour and an addtional $75 as serivce charges

y = 3x + 75

company b charges $2 per hour and an additional $85 as serivce charges

y = 2x + 85

3x + 75 = 2x + 85

x + 75 = 85

x = 10

y = 3*10 + 75 = 2*10 + 85

y = 30 + 75 = 20 + 85

y = 105 = 105

the charge for 10 h is in both companies with $105 the same.

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.
