Area = length x width
length = 3 x width - 5
i.e. 50 = w(3w - 5)
3w^2 - 5w - 50 = 0
(3w + 10)(w - 5) = 0
w = -10/3 or w = 5
but width cannot be negative, hence
width = 5 yd
Length = 3 x 5 - 5 = 15 - 5 = 10 yd
Answer:
a1 = 1/4
a2 = 1/2
a3 = 3/4
a4 = 1
Step-by-step explanation:
an = a/n
then when a= 1, 2, 3, 4
a1 = 1/4
a2 = 2/4 = 1/2
a3 = 3/4
a4 = 4/4 = 1
Let L represent lower level tickets and U upper level.
Starter equations:
L + U = 2368
78L + 59U = 157800
Solve simultaneous equations:
59L + 59U = 139712
so 19L = 18088
L = 952
U = 2368 - 952 = 1416
952 lower level tickets and 1416 upper level tickets were sold.
None of the above
My mom just helped me with it, so I don't know if it's exactly alright. She said it was 20, but theres no 20 as I checked, and I don't know if she didn't right. I got a whole 25.
