5. If a = b, and b = c then a = c is the transitive property.
6. The converse is switching the order of the statement.
The answer would be If A <15, then a <10: true
7. You have RS + ST = RT
Using subtraction property solve for RS by subtracting ST from both sides to get: RS = RT-ST
8. The addition property would be adding the same thing to both sides:
So. If p=q, then p+s = q+s
9. Vertical angles are the same:
6x-22 = 4x+2
Subtract 4x from both sides:
2x-22 = 2
Add 22 to both sides:
2x = 24
Divide both sides by 2:
x = 12
First you had to add by twelve from both sides of equation form.

Then simplify.

Next, add by four-f from both sides of equation form.

Simplify.

Then you divide by ten from both sides of equation form.

Finally simplify by equation.

Final answer: 
Hope this helps!

Answer:
86
Step-by-step explanation:
y + 28 + 58 = 180
y + 86 = 180
y = 180 - 86
y = 94
x + y = 180
x + 94 = 180
x = 180 - 94
x = 86
Answer: Option A is correct.
Step-by-step explanation:
- The correlation coefficient(r) is a statistical measure that computes the strength of the relationship between two variables.
It lies between -1 and 1.
If the correlation coefficient in an ordinary least squares regression = 1.00.
That indicates that there is a perfect relationship between the variables.
i.e. all the data points must fall exactly on a straight line with a positive slope. .
[when r is positive, the slope of the line is positive].
i.e. option A is correct.
