Answer:
487.1
Step-by-step explanation:
100+100=200
200-3=197
197+6=203
203-0.5=202.5
202.5+41=243.5
243.5+0.2=243.7
243.7×2=487.1
Let x = roller coaster ticket
let y = boat ride ticket
x + y = 10
4x + 3y = 37
x = 10 - y
4x + 3y = 37
4(10-y) + 3y = 37
40 - 4y + 3y = 37
-y = 37 - 40
-y = -3
y = -3/-1
y = 3
x = 10 - y
x = 10 - 3
x = 7
x = 7 ; y = 3
4x + 3y = 37
4(7) + 3(3) = 37
28 + 9 = 37
37 = 37

The LCD of 15 and 6 is 30
A. x = -2 and y = -5
check:
x^2 - 9 = 0
B. x = 0 and y = -6
check:
x^2 - 6 = 0
C. x1 = 3, x2 = 5
check:
(x - 3)(x - 5) = 0
D. x1 = 0, x2 = 4
check:
x(x - 4) = 0
