Using the information, we can see that they all refer to Elena as a marker for how much they walked, directly or indirectly.
Let's use E for Elena, J for Jada, and L for Lin.
E + 4 = J
E + 6 = L
E = E
We know they all walked a total of 37 miles.
J + L + E = 37
(E + 4) + (E + 6) + E = 37
Simplify.
3E + 10 = 37
3E = 27
E = 9
Using E is 9, we find that:
Elena walked 9 miles
Lin walked 15 miles
Jana walked 13 miles
13 + 15 + 9 = 37, so our answer checks out.
We know that:
[tex]Jada + Elena + Lin = 37 \space\ miles[/tex][tex]Jada = 4 + Elena[/tex][tex]Lin = 2 + Jada[/tex]Finding the distance each walked:[tex]Jada + Elena + Lin = 37 \space\ miles[/tex]Add 4 both sides
=> [tex]Jada + Elena + 4 + Lin = 37 + 4[/tex]=> [tex]Jada + Jada + Lin = 41 \space\ miles[/tex] [tex][Jada = 4 + Elena][/tex]=> [tex]Jada + Jada + Jada + 2 = 41 \space\ miles[/tex] [tex][Lin = Jada + 2][/tex]Changing "Jada + Jada + Jada" to "3(Jada)"
=> [tex]3(Jada) + 2 = 41 \space\ miles[/tex]Subtracting 2 both sides:
=> [tex]3(Jada) = 41 - 2[/tex]=> [tex]3(Jada) = 39 \space\ miles[/tex]Divide 3 both sides:
=> [tex]3(Jada) = 39 \space\ miles[/tex]=> [tex]\frac{3(Jada)}{3} = \frac{39 \space\ miles}{3}[/tex]=> [tex]\bold{Jada} = \bold{13 \space\ miles}[/tex]Substituting the miles Jada walked into the equation "Jada = 4 + Elena"
[tex]Jada = 4 + Elena[/tex]=> [tex]13 = 4 + Elena[/tex]Subtract 4 both sides:
=> [tex]13 - 4 = 4 - 4 + Elena[/tex]=> [tex]\bold{Elena} = \bold{9 \space\ miles}[/tex]Substituting the miles Jada walked into the equation "Lin = 2 + Jada"
=> [tex]Lin = 2 + 13[/tex]=> [tex]\bold{Lin} = \bold{15 \space\ miles}[/tex]

A flow chart with 3 boxes that are labeled A, B, C, from top to bottom. Box A contains m angle A B C = m angle C B D. Box B contains angle A B C is-congruent-to angle C B D. Box C contains Ray B C bisects angle A B D.
Answers
Answer:
Given that m∠ABC = m∠CBD, and m∠ABD = m∠ABC + m∠CBD BC bisects m∠ABD (Definition of angle bisector)
Step-by-step explanation:
The given information are;
m∠ABC = m∠CBD
To prove that Ray BC bisects m∠ABD
The description is therefore;
Three lines (AB, BC, and BD) that meet at a point
The content of Box A = m∠ABC = m∠CBD
The content of Box B = m∠ABC ≅ m∠CBD
The content of Box C = Ray BC bisects m∠ABD
Therefore, we have;
m∠ABD = m∠ABC + m∠CBD (Angle addition postulate)
m∠ABC = m∠CBD (Given)
∴ m∠ABC ≅ m∠CBD (Definition of congruent angles)
m∠ABC is adjacent to m∠CBD (Description of the angles)
Line BC is common to m∠ABC and m∠CBD (Description of the angles)
Therefore, given that m∠ABC = m∠CBD, and m∠ABD = m∠ABC + m∠CBD BC bisects m∠ABD (Definition of angle bisector).

A rock sample has a mass of 16 grams and a volume of 8 cubic centimeters. 'When the
rock is cut in half, what is the volume and density of each piece?
Answers
Answer:
Volume= 4 cm³
Density= 2 g/cm³
Step-by-step explanation:
We have the following data:
volume= V= 8 cm³
mass= m= 16 g
The density is the mass per volume of a substance, so the density of the rock is:
density= d= 16 g/8 cm³= 2 g/cm³
When we cut the rock in half, we have a half volume and a half mass:
V= 8 cm³/2= 4 cm³
m= 16 g/2= 8 g
But the density is not altered because it is an intrisic property - it does not change with the amount of subtance. Thus, the density of a half rock is:
d = m/V= 8 g/4 cm³= 2 g/cm³

Abby practiced her horn for 3/4 of an hour every day for 12 days?
a) How many hours did she practice in those 12 days?
b) How many minutes did she practiced in those 12 days?
Answers
The time practiced in the 12 days is an illustration of proportions
She practices a total of 9 hours in the 12 daysShe practices a total of 540 minutes in the 12 daysThe total number of hours practicedThe given parameters are:
Days = 12
Proportion = 3/4
So, the number of hours is:
Hours = Days * Proportion
This gives
Hours = 12 *3/4
Hours = 9
Hence, she practices a total of 9 hours in the 12 days
The total minutes practicedThere are 60 minutes in an hour.
So, we have:
Minutes = 9 * 60
Minutes = 540
Hence, she practices a total of 540 minutes in the 12 days

An outlier is a number that is much larger or smaller than the general populous of numbers. For example, if there was a dot plot with dots clustered at 2, 3, and 5, but there was one or two dots around 10, then 10 would be considered an outlier.I would consider 44 to be an outlier in the number set.If I am incorrect in my reasoning, please let me know so that I can plan better for my future answers.

Answers
The total cost of the carpet purchased by the company for its reception is $767.20.
What is the total cost of the carpet?The first step is to determine the total square feet of carpet that would be bought: 1.40 x 68.5 = 95.9 square feet
Now, determine the total cost of the carpet. This can be known by multiplyig the cost per square foot by the total amount of carpet needed.

Answer:
x = -3/2
Step-by-step explanation:
We make both numbers have the same bases.
We know 2^4 = 16 and 2^-6 = 1/64 because a negative exponent means you get the reciprocal of the number.
2^4x = 2^-6
Let exponents equal each other.
4x = -6
x = 6/4 = -3/2

Answer: Use the distance formula to find the length of each side, and then add the lengths.
Step-by-step explanation:
To find the perimeter of this quadrilateral with known vertices: Use the distance formula to find the length of each side, and then add the lengths.
What is distance?The distance between two points is the length of the line joining the two points. Distance is a numerical or occasionally qualitative measurement of how far apart objects or points are. In physics or everyday usage, distance may refer to a physical length or an estimation based on other criteria.
Here, we have,
Mathematically, the distance between points on a coordinate plane is given by this formula:
Formula: distance= √(x_2-x_1)²+(y_2-y_1)²
Where:
x and y are the vertices (points) on a coordinate plane.
Therefore, when the distance formula has been used to determine the length of of each side of the quadrilateral. You should then add the lengths of each side together.
