Given the equation StartFraction 2 x + 2 Over y EndFraction = 4 w + 2 what is the value of x?
x = y w + y minus 1
x = 2 y w + y minus 1
x = 2 y w + y minus 2
x = 4 y w + 2 y minus 2

The value of x is 2yw + y - 1
What is equation?Equation is the defined as mathematical statements that have a minimum of two terms containing variables or numbers is equal.
What is the function?The function is defined as mathematics expression defines a relationship between one variable and another variable. When we say that a variable quantity y is a function of a variable quantity x, we indicate that y depends on x and that value of x determines what value of y will be. This relationship can be expressed as follows: y = f (x)
Given the equation as:
(2x + 2)/y = 4w + 2
To determine the value of x
Multiply by y both sides
y × (2x + 2)/y = (4w + 2) × y
2x + 2 = 4wy + 2y
Subtract 2 from both sides
2x + 2 - 2 = 4wy + 2y - 2
2x = 4wy + 2y - 2
Divide by 2 both sides
x = (4wy + 2y - 2)/2
x = 4wy/2 + 2y/2 - 2/2
x = 2yw + y - 1
Hence, the value of x is 2yw + y - 1.

A nautical mile equals 6,076 feet, and a land mile equals 5,280 feet. How many feet longer is the nautical mile?
Answer:
796 feet
Step-by-step explanation:
The volume of dry goods, like apples or peaches, can be measured usings bushels, pecks, and quarts. A bushel contains 4 pecks, and a peck contains 8 quarts.
What is the relationship between number of bushels, `b`, and the number of quarts, `q`? If you get stuck, try creating a table.
Answer: For every 1 bushel, there will be 2 quarts
Step-by-step explanation:
If 4:8, then you would have to divide. To find how much bushels there are in a quart, you would need to divide each number by 4. 4/4 = 1. 8/4 = 2. So, the relationship between b:q would be 1:2

find the compound interest
on Rs 4000 for 30 months at 10% per annum
Answer:
Rs. 1076.23
Step-by-step explanation:
The compound interest is given by the formula;
A=P(1+r/n )^nt
where
A= amount at the elapse of the period
P= principal amount = Rs=4000
r=rate of interest=10% =0.1
n=number of times the interest is applied per time period= 1
t=number of time periods elapsed = 30 months = 30/12 = 2.5 years
Applying the formula;
A=P(1+r/n )^nt
A=4000( 1+ 0.1/1)^1*2.5
A=4000(1.1)^2.5
A=4000 * 1.2691
A=Rs. 5076.24
Compound interest will be : 5076.24-4000 = Rs. 1076.23
A stem and leaf plot shows the number of kilometers walked for charity. The plot is titled 'Kilometers Walked for Charity.' The numbers 12, 13, 14, 15, 16, and 17 are in a vertical column to the left of a vertical line. · On the same line as 12 but on the right of the vertical line are the numbers 3, 3, 6, 7, 9, and 9. · On the same line as 13 but on the right of the vertical line are the numbers 1, 1, 4, 5, and 5. · On the same line as 14 but on the right of the vertical line are the numbers 0, 0, 2, 3, 3, 8, 8, and 9. · On the same line as 15 but on the right of the vertical line are the numbers 2, 2, 2, 2, 2, 3, 5, 5, and 7. · On the same line as 16 but on the right of the vertical line are the numbers 4, 5, 5, 9, and 9. · On the same line as 17 but on the right of the vertical line are the numbers 3 and 5. The key to the stem and leaf plot identifies that 12 vertical line 3 means 12.3. a. Describe how to find the range of the data set. b. Find the range.
Answer:
For part A: Range is difference between the highest value and lowest value of the data set.
For part B: Range is 5.2
Step-by-step explanation:
For part A:
Range of a data set is difference between the highest value and lowest value of the data set.
For part B:
From stem and leaf and it's key ,we can write our data set as
12.3,12.3,12.612.7,12.9,12.9,13.1,13.1,13.4,13.5,13.5,14.0,14.0,14.2,14.3,14.3,14.8,14.8,14.9,15.2,15.2,15.2,15.2,15.2,15.3,15.5,15.5,15.7,16.4,16.5,16.5,16.9, 16.9, 17.3,17.5.
Lowest value of data set = 12.3
Highest value of the data set =17.5
So, range = highest value- lowest value= 17.5-12.3 =5.2

Answer:
m∠PQR = 133
Step-by-step explanation:
∠PQR and ∠RQS are supplementary angles, meaning they have a sum of 180°.
3x - 5 + x + 1 = 180
4x - 4 = 180
4x = 184
x = 46
Now we simply substitute 46 in for x:
3(46) - 5 = 133
