Answer:
x = 170/34 = 5
Step-by-step explanation:
The sum of angle 1 and angle 2 is 180 degrees. They form a straight line.
So, just add the two equations together, set them equal to 180 and solve for x.
12x+19 + 22x - 9 = 180
34x + 10 = 180
34x = 180 - 10 = 170
x = 170/34 = 10/2 = 5
Answer:
Step-by-step explanation:
a + 9 = 15
a = 15 - 9
a = 6
c + 9 = 16
c = 16 - 9
c = 7
d = c + 9
= 7 + 9
= 16
e = d + 15
= 16 + 15
e = 31
P(selecting a boy) = total boy /total pupils = 16/31
35:105*100 =
(35*100):105 =
3500:105 = 33.33
