You divide each cost to the package for A. to find the better price
Answer:
aₙ = 6n - 6
Step-by-step explanation:
a1 = 6 x 1 - 6 = 0
a₂ = 6 x 2 - 6 = 6
Answer:
17
Explanation:
(x + 8) + (8x + 1) = 90
Combine like terms to get:
9x + 9 = 90
Subtract 9 on both sides:
9x = 81
Divide by 9:
x = 9
Plug in 9 for x in
9 + 8 = ?
9 + 8 = 17

Step-by-step explanation:
The equation isn't properly given. Rather, I will do a similar problem available online. The question is:
The threshold weight T for a person is the weight above which the risk of death increases greatly. The threshold weight in pounds for men aged 40 - 49 is related to height h in inches by the formula
![h=12.3\sqrt[3]{T}](https://tex.z-dn.net/?f=h%3D12.3%5Csqrt%5B3%5D%7BT%7D)
What height corresponds to a threshold weight of 216 Ib for a 43 -year-old man? Round your answer to the nearest inch and then to the nearest tenth of a foot.
<u>Solution:</u>
43 year old man falls into the the age group of 40-49 and thus the formula is shown above.
We want the height "h" corresponding to a weight of 216 pounds. So we plug in 216 into T of the formula and find our answer for h (in inches):
![h=12.3\sqrt[3]{T}\\h=12.3\sqrt{3}{216}\\h=12.3*6\\h=73.8](https://tex.z-dn.net/?f=h%3D12.3%5Csqrt%5B3%5D%7BT%7D%5C%5Ch%3D12.3%5Csqrt%7B3%7D%7B216%7D%5C%5Ch%3D12.3%2A6%5C%5Ch%3D73.8)
The height is 73.8 inches, nearest inch is 74 inches
74/12 = 6.16 feet, nearest feet is 6 ft
