Answer:
6 vertices and 5 faces
Step-by-step explanation:
The faces are correct as there are 3 rectangles and 2 triangles. So a total of 5 faces
There are 6 corners/vertices so the answer is 6 vertices
You have to find the unit rate
SO..
7.70 / 154 = 0.05
So it cost her 0.05 cents for each text.
So then you divide $ 5.25 by the unit rate to get the number of text
5.25 /0.05 = 105
so she sent 105 text
To check it you just multiply the unit rate by the number of text you got and you show come up with $ 5.25
0.05 x 105 = 5.25
The answer is 27, 28, 29.
