Answer:
Part 1: 31x+25=180
part 2: x=5
Step-by-step explanation:
there are 180° on a straight line, which is the base/ bottom line of the traingle (indicated by the arrow on the end).
so, 180-151= 29
29° is the third angle on the traingle.
now, there are 180° in a triangle, therefore to find an equation for x:
29+20x-3+11x-1= 180 (adding up all the angles and making it equal to 180°)
now simplify this equation to get:
31x+25=180 (PART 1)
to find x simply solve the equation:
31x=180-25
31x= 155
x= 155/31
x=5 (PART 2)

You mark the y intercept, and then if the slope is a whole number you give it a denominator of 1, or if it is already a fraction observe, rise over run to calculate each point in the line over the graph.
First we need to find out how many numbers are less than 9.
There are 8 numbers less than 9.
So, to convert this into a percent, we need to put favorable outcomes over possible outcomes.
Favorable outcomes
-----------------------------
Possible outcomes
The possible outcomes is 12, because that is the total number of outcome you can possibly have.
The favorable outcomes is 8, because that is how many number that are less than 9.
So, that gives us this...
8
--
12
Then we can divide to get;
0.6666666
Then we can convert this decimal into a percent by moving the decimal point over 2 times and then rounding.
To get a final answer of 67%.
Hope this helps.
