Rewrite the expression properly

So, we have the following representation

(-6 + 53x - 41x + 6x + 16)÷(x - 8)

Collect the like terms in the above expression

This becomes

(-6 + 53x - 41x + 6x + 16)÷(x - 8) = (53x - 41x + 6x + 16 - 6) ÷ (x - 8)

Evaluate the like terms in the above expression

So, we have the following representation

(-6 + 53x - 41x + 6x + 16)÷(x - 8) = (18x + 10) ÷ (x - 8)

The expression cannot be further simplified

Applying the exterior angle theorem, the measure of the exterior angle to angle X is: B 112.55°.

In other to find the measure of the exterior angle to angle X, we have to recall the theorem known as the exterior angle theorem, which states that the measure of an exterior angle is equal to the two interior remote angles that are opposite to it.

In triangle XYZ, angle Y and Z are the remote interior angles. We are given the following:

Measure of angle Y = 38.25°

Measure of angle Z = 74.3°

Therefore:

The measure of the exterior angle to angle X = measure of angle Y + measure of angle Z

Step-by-step explanation:

\(619 - (270 + 166) = x\)

Therefore, the long dimension of the quilt is (26x + 60)/(x + 6) cm longer than the short dimension.

Area is the measure of the extent of a 2-dimensional surface or region, usually measured in square units such as square meters (m²), square feet (ft²), or square centimeters (cm²). It is the amount of space inside the boundary of a flat shape or the surface of an object.

Here,

The area of the original square is x^2 cm². Maria adds some fabric to one side of the square, which increases the length of the rectangle by a certain amount, and adds a different amount of fabric to the adjacent side, which increases the width of the rectangle by a certain amount. Let's say Maria adds y cm of fabric to one side and z cm of fabric to the other side. Then the length of the rectangle is x + y cm and the width is x + z cm. The area of the rectangle is given by:

(x + y)(x + z) = x^2 + xy + xz + yz

We know that the area of the rectangle is x² + 13x + 30 cm². So we can set these two expressions equal to each other:

x² + xy + xz + yz = x² + 13x + 30

Simplifying this equation, we get:

xy + xz + yz = 13x + 30

We want to find the difference between the length and the width of the rectangle, which is (x + y) - (x + z) = y - z. To solve for y - z, we need to express yz in terms of y - z. We can do this by factoring the left side of the equation above:

xy + xz + yz = y(x + z) + xz = (y - z)(x + y + z)

Substituting this expression for yz in the equation above, we get:

(y - z)(x + y + z) = 13x + 30

We want to solve for y - z, so let's focus on the left side of the equation:

(y - z)(x + y + z) = y(x + y + z) - z(x + y + z)

= xy + y² + yz - xz - z² - yz

= y² - z² + xy - xz

Substituting the expression we found earlier for xy - xz, we get:

(y - z)(x + y + z) = y² - z² + (y - z)(x + z)

(y - z)[x + y + z - (x + z)] = y² - z²

y - z = (y² - z²)/(y - z) = y + z

= (13x + 30)/(x + 6)

So the difference between the length and the width of the rectangle is:

y - z = (13x + 30)/(x + 6)

Therefore, the long dimension of the quilt is (x + y) = x + (13x + 30)/(x + 6) cm, and the short dimension is (x + z) = x + (30 - 13x)/(x + 6) cm. The difference between the long and short dimensions is:

[x + (13x + 30)/(x + 6)] - [x + (30 - 13x)/(x + 6)]

= (13x + 30)/(x + 6) - (30 - 13x)/(x + 6)

= (26x + 60)/(x + 6)

Answer:

y = -3/4 x - 9

Step-by-step explanation:

Slope intercept form is

y = mx+b  where m is the slope and b is the y intercept

9x+ 12y = -108

Subtract 9x from each side

12y = -9x - 108

Divide by 12

12y/12 = -9x/12 -108/12

y = -9/12 x - 108/12

y = -3/4 x - 9

Answer:

y = (-3/4)x - 9

Step-by-step explanation:

Given equation,

→ 9x + 12y = -108

Now we have to,

→ convert into slope-intercept form.

Solving for the value of y,

→ 9x + 12y = -108

→ 12y = -9x - 108

→ y = (-9x - 108)/12

→ y = (-9/12)x - 9

→ y = (-3/4)x - 9

Hence, the form is y = (-3/4)x - 9.

When a die is cut horizontally and vertically, the resulting cross sections are a square and a rectangle, respectively.

A die is a cube with six faces, each having a square shape. When the die is cut horizontally, the resulting cross section will also be a square. This is because the horizontal cut passes through the cube's faces, creating a flat surface with the same shape and size as the original faces.

On the other hand, when the die is cut vertically, the resulting cross section will be a rectangle. This is because the vertical cut intersects two adjacent faces of the cube, creating a flat surface with a rectangular shape.

Therefore, cutting a die horizontally produces a square cross section, while cutting it vertically produces a rectangular cross section.

Using the Bayes' theorem, we find the probability that the transferred ball was white given that the second ball drawn was white to be 52/89, or approximately 0.5843.

To solve this problem, we can use Bayes' theorem, which relates the conditional probability of an event A given an event B to the conditional probability of event B given event A:

P(A|B) = P(B|A) * P(A) / P(B)

where P(A|B) is the probability of event A given that event B has occurred, P(B|A) is the probability of event B given that event A has occurred, P(A) is the prior probability of event A, and P(B) is the prior probability of event B.

In this problem, we want to find the probability that the transferred ball was white (event A) given that the second ball drawn was white (event B). We can calculate this probability as follows:

P(A|B) = P(B|A) * P(A) / P(B)

P(B|A) is the probability of drawing a white ball from urn b given that the transferred ball was white and is now in urn b. Since there are now six white balls and three black balls in urn b, the probability of drawing a white ball is 6/9 = 2/3.

P(A) is the prior probability of the transferred ball being white, which is the number of white balls in urn a divided by the total number of balls in urn a, or 6/13.

P(B) is the prior probability of drawing a white ball from urn b, which can be calculated using the law of total probability:

P(B) = P(B|A) * P(A) + P(B|not A) * P(not A)

where P(B|not A) is the probability of drawing a white ball from urn b given that the transferred ball was black and P(not A) is the probability that the transferred ball was black, which is 7/13.

To calculate P(B|not A), we need to first calculate the probability of the transferred ball being black and then the probability of drawing a white ball from urn b given that the transferred ball was black.

The probability of the transferred ball being black is 7/13. Once the transferred ball is moved to urn b, there are now five white balls and four black balls in urn b, so the probability of drawing a white ball from urn b given that the transferred ball was black is 5/9.

Therefore, we can calculate P(B) as follows:

P(B) = P(B|A) * P(A) + P(B|not A) * P(not A)

= (2/3) * (6/13) + (5/9) * (7/13)

= 89/117

Now we can plug in all the values into Bayes' theorem to find P(A|B):

P(A|B) = P(B|A) * P(A) / P(B)

= (2/3) * (6/13) / (89/117)

= 52/89

Therefore, the probability that the transferred ball was white given that the second ball drawn was white is 52/89, or approximately 0.5843.

Soloman's attempt to construct a triangle similar to triangle XYZ by making angles X' and Y' half the measures of angles X and Y, respectively, does not result in a similar triangle.

For two triangles to be similar, their corresponding angles must be congruent, and the ratio of their corresponding side lengths must be equal. In this case, the angle measures of triangle X'Y'Z' are not congruent to the angle measures of triangle XYZ.

Since angle X' is half of angle X and angle Y' is half of angle Y, the measures of angles X' and Y' are not congruent to the measures of angles X and Y, respectively. Therefore, the triangles are not similar.

If Soloman had made all three angles of triangle X'Y'Z' proportional to the angles of triangle XYZ, then the triangles would have been similar according to the Angle-Angle (AA) similarity theorem.

Step-by-step explanation:

The perimeter of the larger rectangle is 35 millimeters, obtained by multiplying the perimeter of the smaller rectangle (21 millimeters) by the scale factor (5/3).

If the smaller rectangle has a perimeter of 21 millimeters and the scale factor between the smaller and larger rectangles is 3:5, then the perimeter of the larger rectangle can be found by multiplying the perimeter of the smaller rectangle by the scale factor.

The scale factor of 3:5 indicates that the corresponding sides of the smaller rectangle are multiplied by 3, while the corresponding sides of the larger rectangle are multiplied by 5.

Given that the perimeter of the smaller rectangle is 21 millimeters, we can determine the perimeter of the larger rectangle by multiplying the perimeter of the smaller rectangle by the scale factor:

Perimeter of the larger rectangle = Scale factor * Perimeter of the smaller rectangle

= 5/3 * 21

= 35 millimeters

Therefore, the perimeter of the larger rectangle is 35 millimeters, obtained by multiplying the perimeter of the smaller rectangle (21 millimeters) by the scale factor (5/3).
