8*(n+6)=80
distribute
8n+48 = 80
subtract 48 from each side
8n = 32
divide by 8
n=4

Answer:
The area is 63.75 feet square
Step-by-step explanation:
Formula for area of a triangle is 1/2 × base × height
And we are given each of this variables in the question above
Therefore you just have to input those values to the formula
1/2×17/2×15
255/4
=63.75
Therefore the area of the triangle is 63.75 feet square
Inequality is 6t ≤ 44 and Jim can rent a boat for 7.33 hrs or less
<u>
Solution:</u>
Given that
Maximum amount Jim can spend to rent a boat = $34
Rental cost of boat for 1 hour = $6
Also Jim has a discount coupon for $8 off.
Need to determine possible number of hours Jim could rent a boat.
Let’s assume possible number of hours Jim could rent a boat be represented by variable "t"
Cost of renting boat for 1 hour = 6
So Cost of renting a boat for t hours = t x renting boat for 1 hour = t x 6 = 6t
Also Maximum amount Jim can spend to rent a boat = $34
As Jim has a discount coupon for $8 off, so Total amount Jim can spend to rent a boat = $ 34 + $ 8 = $ 44
So cost of renting a boat for t hours must be less that of equal to Total amount Jim can spend to rent a boat
=> 6t ≤ 44
On solving above equality for "t" we get ,

Hence inequality is 6t ≤ 44 and Jim can rent a boat for 7.33 hrs or less.
Answer:
Liam has 4 books. First book is 420 pages, The second book has 70 more pages than the third book while the third and fourth is 150 pages each.
150 + 70 = the second book has 220 pages
420 + 150 + 150 + 220 = 940 pages
And if its asking for the "mean" then take 940 / 4 and you will get 235
