Answer:
v = 10
Step-by-step explanation:
8 = 8v - 4(v+8)
Solve parenthesis
8 = 8v - 4v - 32
Subtract 4v from 8v
8 = 4v - 32
Add 32 on both sides
40 = 4v
Divide by 4 on both sides
10 = v

~AH1807An octagon has seven sides which have a length of k feet. The eighth side has a length of 3.9 feet, as shown below. The perimeter of the octagon is 27.7 feet. What is the value of k?
Answer:
K is 3.4 feet
Step-by-step explanation:
To find the perimeter of the octagon, we add up the lengths of all the sides
For this particular octagon;
7 * k + 3.9 = 27.7
7k + 3.9 = 27.7
7k = 27.7-3.9
7k = 23.8
k = 23.8/7
k = 3.4 feet

Choose the similarity statement that best represents the triangles. Provide evidence.
A. Triangles are similar by AA similarity.
B. Triangle are similar by SAS similarity.
C. Triangles are similar by SSS similarity.
D. Triangles are not similar.
Answer:
A. Triangles are similar by AA similarity.
Step-by-step explanation:
By the Angle Angle Similarity Theorem, if two pairs of corresponding angles are congruent, then the triangles are similar. As a given, Angle E is 35 degrees and Angle B is 45 degrees, which means that Angle R is 100 degrees; By definition, a triangle is 180 degrees in total. Therefore, Angle R is congruent to Angle A. Angles REB and AEZ are also congruent by the vertical angle theorem.
In conclusion, triangles AEZ and REB are similar by the AA similarity theorem.

1 blue marble, and 1 yellow marble. What is the probability of picking a red
marble, and, without replacement, picking a green marble?
Answer:
red - 1/6, green 1/2
Step-by-step explanation:
There is a 1/6 chance that you will pick a red marble because out of the 6 there is 1 red marble
There is a 1/2 or 3/6 chance that you will pick a green marble because out of the 6 there are 3 green marbles

which equation describes the line that passes through (2, 1) (0, -5?
Answer:
well, you probably have options that you didn't include, but..
(-5 -1)/ 0-2
4/ -2
-2 is the slope of the line
and an option of what the equation is:
y - 1 = -2( x - 2)
y -1 = -2x +4
y = -2x +5
Step-by-step explanation:
Ifan equation is an identity, then how many solutions does it have?
Answer:
if solving an equation yields a statement that is true for a single value for the variable, like x = 3, then the equation has one solution. if solving an equation yields a statement that is always true, like 3 = 3, then the equation has infinitely many solutions and is called an identity.

PX,PY, and PZ are the perpendicular bisectors of ARST. Find PS and XT.
Answer:
PS = 82.8 ; XT = 46.1
Step-by-step explanation:
PZ = [tex]\sqrt{TP^2 - TZ^2}[/tex] = √(82.8² - 76.5²) = √1003.59
TZ = SZ = 76.5
PS = [tex]\sqrt{PZ^2 +SZ^2}[/tex] = √(1003.59 + 5852.25) = 82.8 units
XT = RX = 46.1 units
Suppose you want to put a frame around the painting shown at the right. The frame will be the same width around the entire painting. You have 276 in.2 of framing material. How wide should the frame be?
Answer:
The frame should be 36 + 2b + 16 + 2b
Step-by-step explanation:
To solve this question, let assign 36 in x 16 in as the dimension of the painting.
276 in^2 is the area of the framing material to be used.
Let the width of the frame around the frame be "b", thus; the dimension of the frame is 36 + 2b + 16 + 2b

Solve and graph the following inequality: 3(7x+17) > -19 + 14x
Answer:
Solving the inequality we get: [tex]\mathbf{x>-7}[/tex]
Step-by-step explanation:
We need to solve and graph the inequality [tex]3(7x+17) > -19 + 14x[/tex]
Solving:
[tex]3(7x+17) > -19 + 14x[/tex]
Step 1: Multiply 3 with terms inside the bracket
[tex]21x+51 > -19 + 14x[/tex]
Step 2:Subtracting 51 on both sides
[tex]21x+51-51 > -19 + 14x-51\\21x>14x-70\\[/tex]
Step 3: Subtract 14x on both sides
[tex]21x-14x>+14x-70-14x\\7x>-70[/tex]
Step 4: Divide both sides by 7
[tex]\frac{7x}{7}>\frac{-70}{7}\\x>-10[/tex]
Solving the inequality we get: [tex]\mathbf{x>-7}[/tex]
