Acell phone company charges $40 per month for unlimited calling, and $0.20 per text message sent. If t represents the number of text messages Roxy sent last month, which expression represents the cost of her bill last month before
any taxes or additional fees?
40 -0.21
(40 +0.2)
40+ 0.21
(40 -0.2)

 40 + 0.21t

Step-by-step explanation:

If t is the number of texts last month and the initial fee for each month is $40  then you will have the expression 40+0.21t

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.

the answer to this in exact form is 4/35 but in decimal form its 0.1142857

hope this if needed hmu
