The value of x in the equation given as 1/6(x - 3) = 1/3(x + 2) is 7
How to evaluate the equation?The equation is given as
1/6(x - 3) = 1/3(x + 2)
From the question, we can see that the equation is a linear equation with one variable
As a general rule: linear equations are equations that have constant average rates of change.
We start by multiplying both sides of the equation by 6
So, we have the following equation
6 * 1/6(x - 3) = 1/3(x + 2) * 6
Next, we evaluate the products
So, we have the following equation
x - 3 = 2x + 4
Next, we collect the like terms
So, we have the following equation
2x - x = 3 + 4
Evaluate the like terms in the above equation
x = 7
This means that the solution of the equation is 7

a rectangular flying carpet is 1 1/2 meters wide and 2 meters long what is the area of the carpet
The area of 1 1/2 meters wide and 2 meters long carpet is 3 meters².
As per the known fact, the area of rectangular object is calculated by performing multiplication of value of two sides. These two sides are length and width. Firstly converting width from mixed fraction to fraction -
Width = (2×1 + 1)/2
Width = 3/2 meters
Area = length × width
Keep the values in formula to find the value of area of rectangular flying carpet
Area = 3/2×2
Cancelling 2 as it is common in both numerator and denominator
Area = 3 meters²
Thus, the area of rectangular flying carpet is 3 meters².

Bridget sold a total of $135 at her yard sale. If she sold a lamp for $35.50 more than the cost of everything else, what was the cost of the lamp and everything else.
The cost of lamp and everything else will be equal to $85.25 and $49.75 respectively.
This question can be solved by converting it into the form of linear equation. A linear equation can be expressed in the form of y = ax + b where a, b are coefficients and x, and y are independent and dependent variables. We know the total sale which is equal to $135. Let us assume the cost of everything else as x. Now, the cost of lamps is $35.50 more than cost of everything else that is equal to x + 35.50. Now, the linear equation will be written as
135 = x + (x + 35.50)
135 = 2x + 35.50
=> 2x = 99.5
=> x = $49.75 which is the cost of everything else and cost of lamp = x + 35.50 = $85.25.

Write the equation in vertex form to find the maximum height, as well as the time when the maximum height is reached.
The vertex form of a quadratic equation is:
[tex]y=a(x-h)+k[/tex]Where (h,k) is the vertex of the parabola, k is the maximum or minimum value and h is the value of x where that maximum or minimum is reached.
To write h in vertex form, complete the square:

The area of a square inscribed in a circle of a radius square root 70 is 140 units².
What is a square inscribed in a circle?A square is inscribed in a circle if its four vertices are on the circle's circumference. When a square is inscribed in a circle, the diameter of the circle must be equivalent to the diagonal of the square
Given:
The radius of the circle = √70 units
Let the side of the square inscribed in the circle be x units.
Diagonal of the square = [tex]\sqrt{x^{2} + x^{2} }[/tex] = [tex]\sqrt{2} x[/tex]
Diameter of the circle = 2 × √70 ≅ 16.7 units
Now,
Diagonal of the square = Diameter of the circle
[tex]\sqrt{2} x = 16.7[/tex]
[tex]x = \frac{16.7}{\sqrt{2} }[/tex]
x ≅ 11.83 units
So, the Area of the square = (side)² = x²

You plan to work for 40 years and then retire using a 25-year annuity. You want to arrange a retirement income of $3500 per month. You have access to an account that pays an APR of 4.8% compounded monthly. This requires a nest egg of $610,823.48.
What monthly deposits are required to achieve the desired monthly yield at retirement? (Round your answer to the nearest cent.)
The monthly deposit that is required to achieve the desired monthly yield at retirement is $1,056.71.
What is the monthly deposit?An annuity is a series of payment that is made over a period of time. The annuity in this question would last for 25 years. When an investment is compounded monthly, it means that the investment would grow at an exponential rate once in a month.
The formula that would be used to determine the monthly payment is:
Monthly payment = future value / annuity factor
Annuity factor = {[(1+r)^n] - 1} / r
Where:
r = monthly interest rate = 4.8% / 12 = 0.4%n = number of periods = number of compounding x number of years: 12 x 25 = 300$610,823.48 ÷ [{(1.004^300) - 1} / 0.004] = $1,056.71

Target's sells casual sandals for $12 and dress sandals for $22. Total sandals sales were $2,300, and customers bought twice as many casual sandals as dress sandals. How many dress sandals did customers buy? (Hint: Let D = the number of dress sandals.)
Answer:
50 dress sandals
Step-by-step explanation:
Let D = number of dress sandals and C = number of casual sandals
Customers bought twice as many casual sandals as dress sandals. In algebraic form this would be
S = 2D (number of casual sandals = 2 times number of dress sandals)
Since casual sandals sell for $12 each and dress sandals for $22 each, the total sales for S casual and D dress sandals
= 12S + 22D = 2300 (given)
Substitute S = 2D into the above equation to get
12 (2D) + 22D = 2300
24D + 22D = 2300
46D = 2300
D = 2300/46 = 0
Answer: Customers bought 50 dress sandals

line segment QR is parallel to line segment ST. x = ___ m
In order to find the value of x, consider that triangles PQR and PST are similar. Then, you have the following equivalence:
PQ/PS = PR/PT
Where:
PQ = x
PS = 45m
PR = 16m
PT = 36m
replace the previous values of the length of the segments and solve for x, just as follow:
x/45 = 16/36 multiply by 45 both sides
x = (16/36)45
x = 20
Hence, the value of x is x = 20

The domain of the graph is [0,14] and the range of the graph is [0, 7]
In this question, we have been given a graph of height of a falling object.
In this graph, x-axis represents the time in seconds and y-axis represents the height in meters.
We know that, the domain of a graph consists of all the input values which are on the x-axis and the range is the set of possible output values, which are shown on the y-axis.
In this graph we can see that the input (time) takes the values between [0, 14] and the output (height) has values in the interval [0, 7]
Therefore, the domain of the graph is [0,14] and the range of the graph is [0, 7]
