For number 5, if you know that one angle is 65 degrees, then you can find the angle of the supplementary angle by subtracting it from 180:
180 - 65 = 115 degrees < this is what your supplementary angle will be.
Starting from the top, the graph should read:
115 , 65
65 , 115
115 , 65
65 , 115
For number 6, all of the angles are right angles. We know that all right angles have a degree of 90, therefore every angle should be written as 90 degrees. Additionally, in order to find any supplementary angle, you take the known (90) and subtract it from 180. >> 180 - 90 = 90.
Step-by-step Answer:
There is a total of 10 coins, 5 dimes, 2 quarters and three pennies.
By picking a coin, it could be any that shows up out of the 10, so the probability of picking any coin in particular is 1 / 10.
If there are 5 dimes, the probability of picking ANY one particular dime is 1/10, so with 5, the probability of picking ANY of the five dimes is 5/10 = 1/2.
Going along the same line of thought, the probability of picking any of quarters and pennies would be 2/10+3/10 = 5/10 = 1/2 as well.

Answer:
see below
Step-by-step explanation:
It is easiest to compare the equations when they are written in the same form.
The first set can be written in slope-intercept form.
y = 2x +7
y = 2x +7 . . . . add 2x
These equations are <em>identical</em>, so have infinitely many solutions.
__
The second set can be written in standard form.
y +4x = -5
y +4x = -10
These equations <em>differ only in their constant</em>, so have no solutions.
__
The third set is already written in slope-intercept form. The equations have <em>different slopes</em>, so have exactly one solution.
