The variable we need to isolate is P. In order to do so, we add a / 3w on both sides.
P =
The sum of the angles equals 540
There are 3 angles that measure (x - 30) and 2 angles that measure (x)
3(x - 30) + 2(x) = 540
3x - 90 + 2x = 540
5x - 90 = 540
5x = 630
x = 126
x - 30 = 126 - 30 = 96
Answer: x = 126, x-30 = 96
To answer this question here is what you would do. I can't give you the exact answer because there is not a line plot attached.
Count the number of X's above the number 5 1/2 feet. Put this number over the total number of X's you count (including the 5 1/2s).
This is your answer when you write these 2 pieces of information in fraction form.
<span>-8 < x -3 < 1
we have two inequations:
* -8<x-3 and -8+3<x-3+3 or -5 < x or x>-5
* x-3<1 or x-3+3<1+3 and we have x<4
For all cases we have -5<x<4
or </span><span>interval notations: x</span>∈(-5;4)
