Answer:
x = 5
y = 23
Step-by-step explanation:
32x - 70 = 90
32x = 160
x = 5
16y + 92 = 13y + 161
3y = 69
y = 23

Answer:
1250 visitors per day
Step-by-step explanation:
Number of visitors per year = 3,000,000
Number of days open per year = 300
Number of hours = 9a.m to 5pm = 8 hours
Number of visitors per hour :
Number of visitors per year / (number of days per year * number of hours per day)
3000000 / (300 * 8)
3000000 / 2400
= 1250 visitors per day
To solve this you first expand the brackets.
4x^2 - 20x + 25 = 49
Then make it equal 0.
4x^2 - 20x - 24 = 0
Now solve the quardratic.
x^2 - 5x - 6 = 0
(x - 6)(x + 1) = 0
x = 6 or x = -1
The answer is C) 40 degrees
