You have the following algebraic equation:
1/3x = 1/3 + 6/x
In order to solve the previous equation you first multiply both sides of the equation by x, thus, you can quit x denominators in the equation. Proceed as follow:
1/3x = 1/3 + 6/x multiply by x both sides
1/3 = x/3 + 6 multiply by 3 both sides
1 = x + 18 subtract 18 both sides
1 - 18 = x + 18 - 18
-17 = x
-17 = x is the same as x = -17. The solution to the given equation is x = -17.
Find the equation (in slope-intercept form) of the line with the given slope that passes through the point with the given coordinates.
slope: 0, ordered pair: (−3,−8)
The equation (in slope-intercept form) of the line as described whose slope is; 0 and passes through the point given is; y = -8.
What is the equation of the line whose slope is; 0 and passes through the point given;It follows from the task content that the equation of the line whose slope is; 0 and passes through the point; (-3, -8) is to be determined.
Hence, from the slope formula;
slope, m = ∆y/∆x
Therefore; 0 = ∆y/∆x
By cross-multiplication; we have;
∆y = 0
Recall, ∆y = y - y1 = y - (-8)
y - (-8) = 0
y + 8 = 0
y = -8.
Therefore, it follows that the equation of the line described is; y = -8.
Consequently, the line in discuss is a horizontal line.

What is a Rectangular Prism?A rectangular prism is a three-dimensional form with six faces, where all of the faces (top, bottom, and lateral faces) are rectangles and all pairings of opposite faces are congruent. The volume of a rectangular prism is the space that it contains. We know that the volume of any prism is calculated by multiplying its base area by its height.Given:
The volume of rectangular prism = 10368 cubic inches or 6 cubic feet
Height of rectangular prism = 24 inches
It is mentioned that the chest will be twice as long as it is wide.
Let the width of the chest be x inches, so its length is 2x inches.
The volume of the chest = length × width × height
Substituting the values,
10368 = 2x × x × 24
10368 = 2x²× 24
x² = 10368/48

1.064 x 10¹ is 15.2 times larger than the 7 x 10⁻¹. It is obtaining the taking ratio of the given number. Option B is correct.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
We'll apply division by splitting into equal halves or groups, the division may be used to decide how to distribute a dish of cookies evenly among a group.
Let 7 x 10⁻¹ be x times the number 1.064 x 10¹.
The value of x is obtained by taking the ratio of 1.064 x 10¹ and 7 x 10⁻¹.
x = 1.064 x 10¹ / 7 x 10⁻¹
x = 15.2

After 11 years, the account balance is $17,704.987. (approx.)
Compound interest is defined.The principle of the first loan is multiplied by the annual interest rate multiplied by the number of compound periods minus one to calculate compound interest.
The principal of the loan plus compound interest will then be what is left.
Given,
P = $8,216 for the principal value.
Interest rate, r = 7% or 0.07.
Period, with t = 11.
Interest applied n times every time period, or 12 times.
As far as we are aware, A = P(1 + r/n) n*t
where A is the whole sum.
Fill out the formula with the values,
=> A = 8216(1 + 0.07/12) ^ 11*12
