the cost for three packages of moving boxes is modeled by the system of equations below. let s represents the cost of each
small box, m represents the cost of each medium box, and i represents the cost of each large box. which ordered triple (s, m,
represents the costs of the three boxes?
75+4m+21= 24
55+3m+6x = 30
35+ 7m+10/- 46
(1.00, 2.50, 3.50)
(1.00, 2.00, 2.90)
(1.50, 2.00, 2.75)
(1.50, 2.00, 2.00)

answer:

a=9

step-by-step explanation: lmk if you need a explanation

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.

your answer is option c.
