Answer:

If we subtract 14 from both sides of the equation for RU, we get 6p = RU - 14, or 6p = RU - 14. We can then substitute this expression for 6p into the equation for ST to get:

ST = p + 31

ST = (RU - 14) + 31

Expanding RU, we get:

ST = RU - 14 + 31

ST = RU + 17

Since RU = 6p + 14, we can substitute this expression into the above equation to solve for p:

ST = 6p + 14 + 17

ST = 6p + 31

Finally, we can subtract 31 from both sides of the equation to find p:

ST - 31 = 6p + 31 - 31

ST - 31 = 6p

ST - 31 = 6p

p = (ST - 31) / 6

So, to find the value of p, we need to know the value of ST.

Answer:

the number is 78

Step-by-step explanation:

call x is the tens digit (0<x<9)

y is the unit digit (0[tex]\leq[/tex]y[tex]\leq[/tex]9)

we have:

10y+x=[tex]\oveline{yx}[/tex] (1)

10x+y= [tex]\overline{xy}[/tex] (2)

acording (1),(2) and the topic we have: (10y+x)-(10x+y)=9 ⇔9y-9x=9

⇔y-x=1 (3)

and x+y=15 (4)

from (3), (4) we have a system of equation

[tex]\left \{ {{y-x=1} \atop {x+y=15}} \right.[/tex]

⇔[tex]\left \{ {2y=16} \atop {x+y=15}} \right.[/tex]

⇔[tex]\left \{ {{y=8} \atop {x+8=15}} \right.[/tex]

⇔[tex]\left \{ {{y=8} \atop {x=7}} \right.[/tex] (conditions are satified)

the number is 78

Solve for x in one of the equations and substitute it into the other equation.

To solve the system of equations 3x + 5y = 25 and x - 2y = -6 using substitution, we first solve for x in one of the equations. Let's solve for x in the second equation: x = 2y + 6. Next, we substitute this expression for x into the first equation: 3(2y + 6) + 5y = 25. This gives us 6y + 18 + 5y = 25, which simplifies to 11y + 18 = 25. Finally, we subtract 18 from both sides to obtain 11y = 7, and divide both sides by 11 to find y = 7/11. Now that we have y, we can substitute it back into either equation to find x.

Step-by-step explanation:

f(g(4))=5

g(f(3))=4

f(f(2))=2

g(g(5))=0

The value of composition function is:

1. f(g(4)) = 5

2. g(f(3)) = 4

3. f(f(2)) = 2

4. g(g(5)) = 0

To find the value of function focus on the graph of the function.

1. f(g(4))

From the graph of g(x), when x= 4 the value of y is 2.

So, g(4) = 2

Now, the value of f(g(4))

f(g(4))= f(2)

        = 5.

2. g(f(3))

From the graph of f(x), when x= 3 the value of y is 0.

Now, the value of g(f(3))

g(f(3))= g(0)

        = 4.

3. f(f(2))

From the graph of f(x), when x= 2 the value of y is 5.

so, f(2)= 5

Now, the value of f(f(2))

f(f(2)) = f(5)

        = 2

4. g(g(5))

From the graph of g(x), when x= 5 the value of y is 3.

Step-by-step explanation:

The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. If a line is parallel to another line, it means they have the same slope. To find the slope of the line 7x - y = 3, we can rearrange it into slope-intercept form: y = 7x - 3. So, the slope of the line 7x - y = 3 is 7.

Since the line we want to find is parallel to 7x - y = 3 and has a slope of 7, the equation of the line can be written as y = 7x + b, where b is the y-intercept. To find b, we use the point (6, 3) as a solution:

y = 7x + b

3 = 7 * 6 + b

3 = 42 + b

b = -39

So, the equation of the line that passes through (6, 3) and is parallel to 7x - y = 3 is y = 7x - 39.

The total surplus received by both Patricia and Cecilia is $55.

The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.

Given that;

Patricia decides to buy a pair of boots for $90.00. She was willing to pay $120.00.

And, Her friend Cecilia sees the boots, she loves them and thinks they are worth $170.00. So she offers Patricia $145.00 for the boots, and Patricia accepts.

Hence, Consumer surplus is the difference between the willingness to pay of a consumer and the price of the good.

Consumer surplus = willingness to pay – price of the good

Consumer surplus received by Patricia = $120 - $90 = $30

Consumer surplus received by Cecilia = $170 - $145 = $25

Thus, Sum of the surpluses = $30 + $25 = $55

B(n)=(1+2+⋯+n)²---------(2)

Now plug the numbers in the above equations(1)&(2) then,we get:

A(1)=B(1)=1

A(2)=B(2)=9

A(3)=B(3)=36

A(4)=B(4)=100

x = (592 + 817 + 577 + 608 + 353 + 1,281 + 412 + 535 + 550 + 679)/10 = 7,727/10 = $773

The sample median is the middle value when all the values are ordered from smallest to largest:

353, 412, 535, 550, 577, 608, 592, 679, 817, 1,281

The median is 577.

This means that the average sale price for a home in this sample was $773 and that half the sales were for less than the median price of $577, while half were more than the median price of $577.

(b) If the 6th observation had been 985 rather than 1,281, the new mean would be calculated as:

x = (592 + 817 + 577 + 608 + 353 + 985 + 412 + 535 + 550 + 679)/10 = 7,610/10 = $761

The new median would still be $577.

A collection of numbers lined up in rows and columns to form a rectangular array is called a matrix. The elements, or entries, of the matrix are the integers. In addition to numerous mathematical disciplines, matrices find extensive use in the fields of engineering, physics, economics, and statistics. In computer graphics, where they have been used to describe picture rotations and other transformations, matrices have vital applications as well.

Recall that the eigenvalues of a matrix are roots of its characteristic polynomial.

A circle is a round-shaped figure that has no corners or edges. In geometry, a circle can be defined as a closed, two-dimensional curved shape.

Since, no figure is given, we will draw a circle according the given information, [attached in the solution]

So, we get a circle with center O, having chords, BC, which is extended to F, DC and AB,

We have, Angle CBD = 28° and angle FCD = 78°

Therefore,

∠ DCB = 180° - ∠ DCF [Linear pair]

∠ DCB = 180° - 78°

∠ DCB = 102°

In Δ DCB,

∠ DCB + ∠ BCD + ∠ BDC = 180°

The variance clearing account is used to accumulate individual variances until they can be allocated to their respective variance accounts, and the formula used to calculate the variance clearing account is the sum of all the individual variances, plus the beginning balance of the account.

A variance clearing account is a temporary ledger account used to accumulate individual variances such as direct labor cost, direct material cost, and overhead cost. The variance clearing account is used to collect all the individual variances in one account until it can be allocated to its respective variance accounts. This account has a debit side and a credit side. The debit side of the variance clearing account is used to accumulate all the unfavorable variances, while the credit side is used to accumulate all the favorable variances.

The formula used to calculate the variance clearing account is the sum of all the individual variances, plus the beginning balance of the account. This can be expressed as follows:

Variance Clearing Account = Beginning Balance + Sum of All Individual Variances

For example, if the beginning balance of the variance clearing account is $500, and the sum of all individual variances is $400, the balance in the variance clearing account would be $900 ($500 + $400). This balance can then be allocated to the respective variance accounts.
