A quick and easy way to do this particular question is to think all of these numbers are close to 1/2 except 2/31. So, the lowest is 2/31.

Supplementary angles add to 180
4+5=9
180/9=20
4*20=80
5*20=100
the angles are 80 degrees and 100 degrees
Answer:
x=12
Step-by-step explanation:
Cross multiply them:
84 = 7x
Divide By 7 on both sides
12 = x
And there is the answer. Sorry I couldn't explain better Im really not feeling good today

<u>Mona starts from 68th stone</u>
<u>She jumps</u><u> </u><u>23</u><u> </u><u>stones</u><u> </u><u>ahead</u><u> </u>
<u>Then</u><u> </u><u>she</u><u> </u><u>jumps</u><u> </u><u>28</u><u> </u><u>stones</u><u> </u><u>back</u>

<em>Her final position=?</em>




- To find how much stones she is ahead or back we will Subtract 63 from 68 which was her initial position.

So, Mona will be <em><u>5</u></em><em><u> </u></em><em><u>stones</u></em><em><u> </u></em><em><u>behind</u></em><em><u> </u></em><em><u>from</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>starting</u></em><em><u> </u></em><em><u>stone</u></em><em><u>.</u></em>
☯️Hence, Option C is correct
-3b=-9. Plug in 3. -3(3)=-9.
