Answer:
{x\ x e U and x has a negative square root} is an empty set.

The admission fee at a fair is $2.00 for children and $4.00
for adults.
On Saturday 2,500 people entered the fair and $7,000.00 were
collected.
How many children and how many adults attended? Give your
answer, using x for children, y for adults.
Form of: x =, and y =
Let K = no. of children
Let A = no. of adults
2500 people mean
Kids + Adults
K + A = 2500
K = 2500 – A
2K + 4A = 7000
K + 2A = 3500
(2500 – A) + 2A = 3500
A = 3500 – 2500
(A = 1000, adults)
K = 2500 – A
K = 2500 -1000
(K = 1500, Kids)
CHECK:
1500*2 = $3000
1000*4 = $4000

Answer:
x = 11
Step-by-step explanation:
x + 5 = 2(x - 3)
x + 5 = 2x - 6
(x - x) + 5 = (2x - x) - 6
5 = x - 6
5 + 6 = x (- 6 + 6)
x = 11
