The increase is 1150 ... 11.5 times the original value, or 1150% of it. That's a big increase, and I would not buy that thing, whatever it is.
Well you draw a diagonal line across the parallelogram and then do the pythogorean theroem with the base and height and you'll have the hypotenuse/diagonal
To solve this problem you must apply the proccedure shown below:
1. The arithmetic sequence is:
Where is the nth termn, is the first term, is the common difference between the terms and is the number of the term.
2. Based on the information given in the problem, you have:
3. When you substitute these values into the formula, you obtain:
The answer is: seats
2(5x+7)+8x-7=27
We move all terms to the left:
2(5x+7)+8x-7-(27)=0
We add all the numbers together, and all the variables
8x+2(5x+7)-34=0
We multiply parentheses
8x+10x+14-34=0
We add all the numbers together, and all the variables
18x-20=0
We move all terms containing x to the left, all other terms to the right
18x=20
x=20/18
x=1+1/9
