lookon bbcbitesize for adding negatives and positive rule
Total age of pupils
= 12.7 x 10
= 127 years
127 - 11 - 10 - 12 - 11 - 14 - 13 - 14 - 16 = 26 ( total age of the other 2 pupils added together )
however, since the ninth pupil is two years younger,
26-2=24
24/2=12 ( age of ninth pupil )
12+2=14 ( age of tenth pupil )
thus, (a) 12 years old,
(b) 14 years old.

Step-by-step explanation:
Let No. Of Student tickets sold be X and No. Of general tickets sold be Y respectively.
Total tickets sold :
(a) X + Y = 92
Total earnings from tickets sale:
(b) 5X + 8Y = 610
Solving equations (a) and (b), we get :
<u>X = 42 tickets </u>
<u> Y = 50 tickets</u>
Answer:
<em><u>M(-2,-6)</u></em>
y-axis (-2,6)
x-axis (2,-6)
<u><em>N(4,1)</em></u>
y-axis (4,-1)
x-axis (-4,1)
Step-by-step explanation:
When the point is reflected across the x-axis then the y value will change signs.
When the point is reflected across the y-axis then the x value will change signs
