Answer:
uₙ₊₁ = uₙ + ¹/₂
Step-by-step explanation:
uₙ₊₁ = uₙ + d
u₈ = 3
u₁₀₀ = 49
We can establish the following:
u₉ = 3 + d
u₁₀ = (3 + d) + d = 3 + 2d
u₁₁ = (3 + 2d) + d = 3 + 3d
so...
u₈₊ₐ = 3 + ad
u₁₀₀ = u₈₊₉₂ = 3 + 92d
3 + 92d = 49
92d = 46
d = ¹/₂
∴ uₙ₊₁ = uₙ + ¹/₂
Answer:
−243−62+12
Step-by-step explanation:
Start with all the fixed costs
- Entry into the cab = 3.15
- Cost of three extras = 3*1.75 = 5.25
- Tip = 42/8 = 5.25
<em><u>Total Fixed Costs</u></em> 13.65
<em><u>Amount Spent on Mileage</u></em> 42 - 13.65=28.35
Now set up the proportion for the mileage using cost
<em><u>2/9 mile </u></em> = x
0.45 cents 28.35
Multiply both sides by 28.35
(2/9) * 28.35 / 0.45 = x
Put this into your calculator as
(
2/9
)
*
28.35
/
0.45
=
14
The answer is 14 miles traveled.
Answer:
y = 3
Step-by-step explanation:
(5y - 3)/4 + 6 = 3y
5y - 3 + 24 = 12y
7y = 21
y = 3
Check.
(5*3 - 3)/4 + 6 = 3*3
(15 - 3)/4 + 6 = 9
12/4 + 6 = 9
3 + 6 = 9
9 = 9
