Answer:
Step-by-step explanation:
a= adult ticket
a= student ticket
5a+1s=2874
1a+1s=1246
Subtract the second equation from the first one
4a=1628
a=407
a+s=1246
407+s=1246
s=839
as AB || DE then
angle BAE = angle AED
so angle AED = 70
as AD = AE then
angle AED = angle ADE = 70
now in a triangle
angle DAE + Angle ADE + angle AED = 180
angle DAE + 70 + 70 = 180
angle DAE = 180 - 140 = 40
Answer:
a) 42. b) 64. c) 39.
Step-by-step explanation:
a. 6 x 7 = 42
b. 8 x 8 = 64
c. 3 x 13 = 39
(60 / - 20 ) x 100% = 300%
