Let the number of child tickets sold be x, and number of adult tickets be y, then
5.70x + 9.50y = 543.40 . . . (1)
y = 2x . . . (2)
Putting (2) into (1), gives
5.7x + 9.5(2x) = 543.4
5.7x + 19x = 543.4
24.7x = 543.4
x = 543.4/24.7 = 22
Therefore, 22 child tickets were sold.
Answer:
2 distinct solutions
Step-by-step explanation:
discriminant is b²-4ac
b = 3
a = 1
c = -7
discriminant = 9-4(-7) = 9+28 = 37
You have to distribute the radical negative 18 in first. Simplifying from there, you’ll prob have to get into imaginary numbers since the square root of a negative is imaginary
Jason = J, Kim = K
K+325m = J
K = 4.2 km
convert km to m by multiplying by 1000
4.2km * 1000 = 4200m = K
so just plug in your values to get your answer : Jason ran 4525 meters
4200m + 325 = 4525m
