Circumference = pi * diameter
diameter = 8.5; pi = 3.14
C = 3.14 * 8.5
C = 26.69 in = 26.7 in
Answer:
1. Calculate the slope from 2 points.
2. Substitute either point into the equation.
3.Solve for b, which is the y-intercept of the line.
4. Substitute b, -1, into the equation from step 2.
Step-by-step explanation:
I gave you one extra than what you expected, if thats ok.
Hope this helps : )
X = the age of Mr. Gilliam
His wife is 3 years older, so the age of Mr. Gilliam's wife = x+3
The sum of their ages is 95.

Mr. Gilliam is 46 years old.
4x-10 and 7x-8 are supplementary angles and thus add up to 180 degrees.
Thus, 11x - 18 = 180 degrees.
Combining like terms, 11x = 198, and x = 18.
The two supplementary angles are 4(18)-10 and 7(18)-8, or 62 and 118 degrees.
Answer:
B. 4.5
Step-by-step explanation:
(6x + 42)° and (18x - 12)° are alternate interior angles. If line l is parallel to line m, therefore,
6x + 42 = 18x - 12
Solve for the value of x. Combine like terms.
6x - 18x = -42 - 12
-12x = -54
Divide both sides by -12
-12x/-12 = -54/-12
x = 4.5
Therefore, x = 4.5 would prove lines l and m are parallel to each other.
