32x-96
Step-by-step explanation:
8 · 4x = 32x
8 · 12 = 96
Its A or C because Angle AEC has to be bigger then 90 degrees
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
