This is timed!!! It is a math equation that I am too lazy to solve.
Answer: Below
Step-by-step explanation:
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]

Step-by-step explanation:
[tex]16 {}^{x} = \frac{1}{64} [/tex]
[tex]4 {}^{2x} = 4 {}^{ - 3} [/tex]
[tex]2x = - 3[/tex]
[tex]x = - \frac{3}{2} [/tex]
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
x = -3/2

Are there any outliers in the data? What does the outlier mean?
Answer:
44, definition below
Step-by-step explanation:
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. Have an amazing day.
Answer: I think it's 44
Step-by-step explanation: Outlier means the one that stands out from the rest. As you can see most of the numbers are in between 50 and 90 but 44 is not so it is 44.

A company figured it needed 68. 5 square feet of carpet for its reception room. To allow for waste, it was decided to order 40 percent more material than needed. Fractional parts of square feet cannot be ordered. At $8. 00 per square foot, how much would the carpet cost?
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.
95.9 x 8 = $767.20

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?
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

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.

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?
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

That is, the event A ∪ B will occur if either A or B occurs. In Example 4.1(a), if A = {g} is the event that the child is a girl and B = {b} is the event that it is a boy, then A ∪ B = {g, b}.
