Answer:
Senior citizen tickets = 9
Student tickets = 10
Step-by-step explanation:
We begin by converting the question into simultaneous linear equations;
Senior citizen tickets = a
Student tickets = b
4a + 6b = 96
8a + 13b = 202
to find a,
if 4a +6b = 96
a = 96/4 - 6b/4
a = 24 - 1.5b
We now substitute this into the second equation
8(24 - 1.5b) + 13b = 202
192 - 12b + 13b = 202
b = 202 - 192
b = 10
We now put the value of b in either equation
4a + 6b = 96
4a + 6(10) = 96
4a + 60 = 96
4a = 96 - 60
4a = 36
a = 9
Answer:
option 3
Step-by-step explanation:
Answer:
Square Area = ( one side length)²
784 = (AB)²
AB = 28
circle radius = 14
pi = 3.142
semi circle parameter = pi × r
= 3.142 × 14 = 43.988
square parameter = 3 × 28 = 84
we dont calculate the 4th side.
parameter of the figure = 43.988+ 84= 127.988
