Answer:
92
Step-by-step explanation:
Let the number be x.
As per the question,
3/4x - 18 = 1/2x + 5
(4)3/4x - (4)18 = (4)1/2x + (4)5
3x - 72 = 2x + 20
x = 92
The number is 92.
I got the answer right, I just took the test: (going from left to right)
Fish+Bird= 6
Bird+Not fish= 8
Total= 14
Fish+Not bird= 19
Not fish+Not bird= 22
Total= 41
(Now going down the column)
Fish total= 25
Not fish total= 30
Total+Total= 55
The two equations:
Daisy’s: y = 4x + 14
Donald’s: y= 2x + 26
The point of intersection is (6, 38)
This point refers to how many of passengers it will take for both equations to have have the same cost output.
Daisy’s deal is better if you have less than 6 passengers. We can tell because the line for the equation is lower than Donald’s line. Donald’d deal will be better if you have more than 6 passengers since the line is lower than daisy’s deal.
Note that
10² = 100
0.08² = 0.0064
and
101.6064 = 100 + 1.6 + 0.0064
It also happens that
1.6 = 2 • 10 • 0.08
which means
101.6064 = 100 + 1.6 + 0.0064
101.6064 = 10² + 2 • 10 • 0.08 + 0.08²
101.6064 = (10 + 0.08)²
101.6064 = 10.08²
which means
√101.6064 = 10.08
which, to one decimal place, is approximately 10.1.
