Answer:
12 = 4 (k - 6) (use the distributive property to get rid of the parentheses)
12 = 4k -24 (add 24 to both sides to isolate the k-term)
36 = 4k (divide both sides by 4 to get k all alone)
k = 9 (your answer)

Answer:
measure of Arc FJ is 80 degrees.
Step-by-step explanation:
Key skills: High School Geometry, One Variable Equations, Angles
1)Let's look at the diagram thoroughly
2) The 2 thing we can get are:
Angle HKG and Angle IKJ are vertical angles (which means they are congruent). Angle HKG + Angle GKF + Angle FKJ = 180 (Since they all form a straight angle - A straight angle is 180 degrees in measure.)3) First we can use the fact that Angle HKG and Angle IKJ are vertical angles. This makes them congruent (Or equal in size)
We can then solve for x by making the equation: 3x-22=x+104) Solve this by moving the x's to one side, and the numbers to the other. You would then get: 3x-x=10+22
3x-x= 2x 10+22=32
2x=32
Divide by 2 on both sides and x=16.
5) We get that x=16. Now to find the measure of Arc FJ, we need to use the fact that Angle HKG + Angle GKF + Angle FKJ = 180
What we want to find is Angle FKJ. The measure of Angle FKJ would be the measure of Arc FJ
6) We can make an equation: x+10+74+Angle FKJ=180
Solve this --> x=16, so substitute it in16 + 10 + 74 + Angle FKJ=180100 + Angle FKJ = 180Angle FKJ = 80 degreesIf Angle FKJ is 80 degrees, then Arc FJ measures 80 degrees.

Luke had $8.50. He spent $1.25 on sweets and gave to his two friends $1.20 each. How much money was left?
Answer:
4.85 left
Step-by-step explanation:
Answer:
$4.85
Step-by-step explanation:
Amount John has = $8.50 (Given)
Find amount left after spending on sweet
Sweet = $1.25
Amount left = $8.50 - $1.25 = $7.25
Find amount left after giving to 2 friends:
First friend = $1.20
Second friends = $1.20 x 2 = $2.40
$7.25 - $2.40 = $4.85
Answer: $4.85

Carol and Diane are axe throwers. Carol hits the board on 44% of her throws, while Diane hits the board on 42% of her throws. Suppose that Carol throws 25 axes at the board and Diane throws 28. Let C = the proportion of axes that hit the board when Carol throws and D = the proportion of axes that hit the board when Diane throws. What is the probability that Diane’s proportion of axes hitting the board is higher than Carol’s?

Line q passes through the points (4, 6) and (0, 6). What is the equation for the line which is perpendicular to q and passes through the point (–2, 3)?
Answer:
x = -2Step-by-step explanation:
The slope of q:
[tex]m_q=\dfrac{6-6}{4-6}=0[/tex]
It means the line q is parallel to X-axis. Therefore any line perpendicular to q is parallel to Y-axis.
Any line parallel to Y-axis is: x = x₀, where x₀ is the x-coordinate of any point the line passing through.
(-2, 3) ⇒ x₀ = -2

Does this expression use the distributive property?
(6x + 3) + (5x - 4)
no because you are not distributing numbers that multiply with each other and form new expressions
Answer:
hm I'm not sure but you solve it like this

A. reflection over the north-south axis
B. rotation
C. translation
D. reflection over the west-east axis\
Answer:
10 paces East

25 POINTS. Radar used microwaved yo check the speed of cars. If a speed of the microwaves is 2 000 000 m/ s and the wavelength is 0.0345m calculate the frequency.
Answer: [tex]5.79\times 10^{7}\ \text{Hz}[/tex]
Step-by-step explanation:
Given
Speed of radar wave [tex]v=2\times10^{6}\ m/s[/tex]
the wavelength of radar wave [tex]\lambda =0.0345\ m[/tex]
We know, [tex]velocity=frequency\times wavelength[/tex]
[tex]frequency=\dfrac{\text{velocity}}{\text{wavelength}}[/tex]
[tex]frequency=\dfrac{2\times10^6}{3.45\times10^{-2}}[/tex]
[tex]frequency=5.797\times 10^{7}\ Hz[/tex]

Jaclyn is training for a long bike ride. Right now, her longest ride is miles. She plans to add miles each week to her longest ride. Use a linear equation to determine the length of Jaclyn's longest ride after weeks. Do not include units in your answer.
Values in the question are missing ; we could get some input for the missing values and solve the question asked :
Jaclyn is training for a long bike ride. Right now, her longest ride is 36 miles. She plans to add 2 miles each week to her longest ride. Use a linear equation to determine the length of Jaclyn's longest ride after 6 weeks. Do not include units in your answer.
Answer:
48 miles
Step-by-step explanation:
Given that:
Longest ride (initial) = 36 miles
Additional miles per week = 2 miles
y(x) = mx + c
c = initial ride ; m = rate (increase in miles per week) ; x = number of miles per week
Longest ride after 6 weeks will be :
[Longest ride (initial) + additional miles per week * number of weeks]
Longest ride after 6 weeks :
36 miles + (2 * 6)
36 + 12
48 miles after 6 weeks

Trevor measured the town library and made a scale drawing. In real life, the parking lot is 75 meters long. It is 135 centimeters long in the drawing. What scale did Trevor use? 9 centimeters : meters
Answer: [tex]9\ cm\equiv 5\ m[/tex]
Step-by-step explanation:
Given
The actual length of the parking lot is 75 m
length in the drawing is 135 cm
Here, 75 m is equivalent to 135 cm
Using unitary method
[tex]75\ m\equiv 135\ cm[/tex]
[tex]15\ m\equiv 27\ cm[/tex]
[tex]9\ cm\equiv \frac{15}{3}=5\ \text{m}[/tex]
a graphic artist has a picture that is 5 in by 10 in the picture needs to be in large so the larger side is 30 in the ratio of the sides lengths will remain the same how long will the shorter side be after the enlargement
Answer:15
Step-by-step explanation:
the ratio is 1:2 so 5 is half of 10 and if 10 becomes 30 it’s tripled so you would then have to triple 5 getting 15 , i hope this is right if not i’m sorry
Might give you Brainliest is you step by step explain how much you get the answer
Answer:
60
Step-by-step explanation:
There were 160 votes in total, and we need to figure out how much is 3/8 of it. Therefore, we need to find (3/8)*(160) (of is another word for multiply). The easiest method is to find 1/8 of 160 which is 20, and then multiply it by three to get 60, which is your answer!
I hope this helped, please give brainliest if this is correct! Thank you!
