Divide each term by 6 and simplify.
x = −9
Number of books each of them have:
Jaime: x
Grant: x - 6
Ky: 3 (x - 6)
There are 176 books in total, so we can write it down as:
176 = x + x - 6 + 3 (x - 6)
176 = x + x - 6 + 3 * x + 3 * (-6)
176 = x + x - 6 + 3x - 18
176 = 2x - 6 + 3x - 18
176 = 5x - 24 / + 24 (both sides)
5x = 200 / ÷ 5 (both sides)
x = 40
Doublecheck:
Jamie: 40
Grant: 40 - 6 = 34
Ky: 3 (40 - 6) = 3 * 34 = 102
102 + 34 + 40 = 176, so it's correct :)
Find the area of each individual shape and add those answers to get the entire sum
Answer:
Average number of people ride ferry boat = 62 or 63 people
Step-by-step explanation:
Given:
Number of people ride ferry boat
58 59 60 61 62 63 64 65 66 67
Find:
Average number of people ride ferry boat
Computation:
Average mean = Sum of all observation / Number of observation
Average number of people ride ferry boat = [58 + 59 + 60 + 61 + 62 + 63 + 64 + 65 + 66 + 67] / 10
Average number of people ride ferry boat = [625] / 10
Average number of people ride ferry boat = 62.5
Average number of people ride ferry boat = 62 or 63 people
The term of this sequence is:
<span>-(17/30)n^5+(113/12)n^4-(173/3)n^3+(1915/12)n^2-(5813/30)n+85 </span>
<span>Therefore,term number 7 is:-146/1=-146 </span>
