Answer:
2 + (3 + 4) = (2 + 3) + 4
Answer:
b = 
Step-by-step explanation:
Given
a = 
( multiply both sides by 3b - 2 )
a(3b - 2) = b + 1 ← distribute left side
3ab - 2a = b + 1 ( subtract b from both sides )
3ab - b - 2a = 1 ( add 2a to both sides )
3ab - b = 1 + 2a ← factor out b from each term on the left side
b(3a - 1) = 1 + 2a ( divide both sides by 3a - 1 )
b =
Answer: 3/8 of a mile
Step-by-step explanation: To make this a bit more understandable, 7/8 cannot have a denominator of 2 since the numerator is 7, so what we do is make 1/2 of a mile have a denominator of 8. So we turn 1/2 to 4/8 to make the fractions more easier to use by multiplying 1/2 by 4.
1/2 X 4 = 4/8
So, Dawn rode 4/8 of a mile and she needs to get to a point where it is 7/8 of a mile away from her starting point. When you subtract fractions, you do not have to worry about the denominator, just the numerator.
7/8 - 4/8 = 3/8
Therefore, dawn must hike 3/8 of a mile more to reach her goal. :)

Answer:
- an = 160·0.85^(n-1)
- $51.29
Step-by-step explanation:
In the given formula, a1 refers to the first term of the sequence (160), and r refers to the common ratio (136/160 = 0.85). Putting these values into the formula gives ...
a) Explicit formula: an = 160·0.85^(n-1)
__
b) The 8th term is found by putting n=8 into the formula and doing the arithmetic:
a8 = 160·0.85^(8-1) ≈ 51.29
After 8 months, the price is predicted to be $51.29.
