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

If a 12-sided regular polygon rotates about its center, at which angle of rotation will the image of the polygon coincide with t
Snowcat [4.5K]
Central angle of a regular polygon:
Ф = 360° : n. 
If n=12:  Ф = 360° : 12 = 30°
At the angle of rotation Ф = 30°  the image of the polygon will coincide with the preimage.

Which point is a distance of 5 units from the point (1,9)?
Fantom [35]
You just need to plot them on a graph and see how many spaces are in between each.  So if you plot (1,9) remember it's X, Y axis.  Start from zero on the graph.  Since it's positive go over 1 to the right and up 9.  Then do the same for the rest. Then count how many units are between each point on the graph and find the one that is 5 units apart.
