Answer:
57 adult tickets, 86 student tickets
The Pythagorean theorem tells you the distance between the locations is
√(52² +75²) ≈ 91.23 mi
The appropriate choice is
B. 91 mi
_____
An approximation that can get you within 6% of the correct value is this: add 1/3 of the short side of the right triangle to the long side. Here, that is
75 + 52/3 = 92.3
This is close enough to the correct value to let you choose the correct answer.
Answer:
(-(5 x^3 + 40 x^2 + 24))/(8 x^2) - I can't read the picture yousend it's way to small.
Step-by-step explanation:
Simplify the following:
x - (5 x)/8 - x - 5 - 3/x^2
Put each term in x - (5 x)/8 - x - 5 - 3/x^2 over the common denominator 8 x^2: x - (5 x)/8 - x - 5 - 3/x^2 = (8 x^3)/(8 x^2) - (5 x^3)/(8 x^2) - (8 x^3)/(8 x^2) - (40 x^2)/(8 x^2) - 24/(8 x^2):
(8 x^3)/(8 x^2) - (5 x^3)/(8 x^2) - (8 x^3)/(8 x^2) - (40 x^2)/(8 x^2) - 24/(8 x^2)
(8 x^3)/(8 x^2) - (5 x^3)/(8 x^2) - (8 x^3)/(8 x^2) - (40 x^2)/(8 x^2) - 24/(8 x^2) = (8 x^3 - 5 x^3 - 8 x^3 - 40 x^2 - 24)/(8 x^2):
(8 x^3 - 5 x^3 - 8 x^3 - 40 x^2 - 24)/(8 x^2)
Grouping like terms, 8 x^3 - 5 x^3 - 8 x^3 - 40 x^2 - 24 = (8 x^3 - 8 x^3 - 5 x^3) - 40 x^2 - 24:
((8 x^3 - 8 x^3 - 5 x^3) - 40 x^2 - 24)/(8 x^2)
8 x^3 - 8 x^3 - 5 x^3 = -5 x^3:
(-5 x^3 - 40 x^2 - 24)/(8 x^2)
Factor -1 out of -5 x^3 - 40 x^2 - 24:
Answer: (-(5 x^3 + 40 x^2 + 24))/(8 x^2)
Answer: -7-4
Step-by-step explanation:
7B + 4 = 7B - 3
We need to solve for B
Let's add 3 in both sides:
7B + 4 = 7B - 3
7B + 4 + 3 = 7B - 3 + 3
7B + 7 = 7B
Let's subtract 7B from both sides:
7B + 7 = 7B
7B - 7B + 7 = 7B - 7B
7 = 0
7 = 0, which is impossible. 7 can never be 0, and 0 can never be 7.
So the equation have no solution.
