Answer:
yes done open those link i get them all the times
Step-by-step explanation:
The radius is half the diameter. 19*2=38. The diameter is 38.
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
She should chose the $9 because it is cheaper ;)
Y can equal 3, if x=0. i hoped i helped. please mark my responce as brainiest.
