For a solution to exist for two lines, y=y so we can say:

-3=7x-10  add 10 to both sides

7=7x  divide both sides by 7

x=1

So the solution is the point (1, -3)

1. Convert 60° to radians.
hram777 [196]

Answer:

60° = \frac{\pi }{3} radians

Step-by-step explanation:

To convert from degrees to radians

radian measure = degree measure × \frac{\pi }{180}

Thus 60° in radian measure

= 60 × \frac{\pi }{180} ( divide ( cancel) 60 and 180 by 60 )

= \frac{\pi }{3}

30 points.. Please Help! I don't understand what to do with this question...a bit confused.
Romashka-Z-Leto [24]
  Eh, here's my best try for a table:

                       <u>Like tv</u>          <u> don't like tv</u>       <u>total</u>
<u>Like reading:</u>     70                     10                 80
 <u>Don't like read</u>. <u>20</u>                     <u>30</u>               <u>50 </u> 
      <u>total </u>              90                    40               130

The percentage of students that like tv as well as reading is- 70 divided by 130 which gives you .538 which in percentage is 53.8%.

The probability of a student that does not prefer to watch tv as also does not like to spend their time reading is 30 over 40 which can be simplified or reduced to 3 over 4. [30/40 reduced to 3/4]

Hope this somehow helped you :)
