Step-by-step explanation:
1) Number of children = c
Number of adults = a
Total ticket = 250
c + a = 250 -------------------(I)
Cost of 'c' children tickets = 200c
Cost of 'a' adult tickets = 450a
Total cost = 76000
200c + 450a = 76000 ------------------(II)
Multiply (I) by (-200) and then add
(I)*(-200) -200c - 200a = -50000
(II) <u> 200c + 450a = 76000 </u>
<u> </u> 250a = 26000
a = 26000/250
a = 104
Plug in a = 104 in equation (1)
c + 104 = 250
c = 250 - 104
c = 146
2)Number of children = 146
Number of adults = 104
Answer:
A rectangle and an equilateral triangle have the same perimeter
The perimeter of the rectangle is 2x+2(3x-1) inches
The perimeter of the equilateral triangle is 3(x+1) inches
Solve the value of x and the perimeter of each figure
Sin x =cos 19
X =sin^1(cos 19)
X=71
