A cell phone provider offers a plan that cost $20 per month plus $0.10 per text messages sent or received a comparable plan cost $50 per month but offers unlimited text messaging how many text messages would have to be sent received in order for the plans to cost the same each the same each month

300 text messages would have to be sent/recieved per month in order for the plans to cost the same.

Step-by-step explanation:

x=month    y=text message

20x+0.10y

50-20=30

30/.10=300

20(1)+0.10(300)=50

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
