X - y/2z=3 solve for x

Answer:

H= -35/4

Decimal form: -8.75

Explanation:

Compared to Monday, Gordon ran for an additional 15 minutes on Wednesday.

Let x be the number of additional minutes Gordon ran on Wednesday compared to Monday. Then, we can write an equation based on the given information:

43 minutes (Wednesday) = 28 minutes (Monday) + x minutes (additional time on Wednesday)

To solve for x, we can isolate it on one side of the equation:

43 minutes - 28 minutes = x minutes

15 minutes = x

Therefore, Gordon ran 15 more minutes on Wednesday compared to Monday.

The simplified expression is adbc - bc - abd√c - b√ad√c + acd√b + cd√ab.

In mathematics, the distributive property is a property of operations that involves multiplying a factor by a sum or difference of terms. The distributive property states that the product of a factor and a sum or difference of terms is equal to the sum or difference of the products of the factor with each term individually. In other words, for any numbers a, b, and c, the distributive property can be expressed as:

a(b + c) = ab + ac

Given expression

(a√b+c√d)-b√a)×(d√c-√ab+abc)

Simplifying the expression

(a√b+c√d-b√a)×(d√c-√ab+abc)

by simplifying the given expression using the distributive property of multiplication:

(a√b+c√d-b√a)×(d√c-√ab+abc)

= adbc + acd√b - abd√c - b√ad√c + cd√ab - bc

= adbc - bc - abd√c - b√ad√c + acd√b + cd√ab

Therefore, the simplified expression is adbc - bc - abd√c - b√ad√c + acd√b + cd√ab.

Amount of calcium in a tablet = 300 mg

Find:

Number of tablet needed

Computation:

Number of tablet needed = Amount of calcium per day needed / Amount of calcium in a tablet

Number of tablet needed = 1 tablet

The expression of logarithmic function, f(x) = ln (1/gᵏ) after all possible expansion is equals to the f(x) = - k × ln( g).

In mathematics, the logarithmic function is defined as inverse function to exponent function and defined as f(x) = logₐx where a is base of function. Properties of Logarithmic Functions :

We have, a natural logarithmic function, i.e., base = 10, f(x) = ln (1/gᵏ) and we have to expand it. To expand logarithms means write them as a sum or difference product of logarithms. The order to apply rules is quotient rule, product rule and then power rule. So, f(x) = ln (1/gᵏ)

applying quotient rule,

=> f(x) = ln(1) - ln( gᵏ)

Appling power rule,

=> f(x) = ln(1) - k ln( g)

Applying Zero Exponent Rule,

=> f(x) = 0 - k × ln( g)

Hence, the required expansion is f(x) = - k × ln( g).

So the new coordinates of point C are (1, 2), and the image of Triangle ABC is congruent to the original triangle.

A triangle is a closed, two-dimensional geometric figure with three straight sides and three angles. It is one of the basic shapes in geometry and can be classified based on the length of its sides or the size of its angles. A triangle with all sides of equal length is called an equilateral triangle, while a triangle with two sides of equal length is called an isosceles triangle. A triangle with no sides of equal length is called a scalene triangle. Triangles can also be classified based on the size of their angles, with an acute triangle having all angles less than 90 degrees, a right triangle having one angle equal to 90 degrees, and an obtuse triangle having one angle greater than 90 degrees.

Here,

To find the new coordinates of point C after the rotation and translation, we need to perform each transformation separately and then combine them.

Rotation:

To rotate a point 180° counterclockwise about the origin, we switch the sign of both coordinates. Therefore, the new coordinates of point C after the rotation are (-3, -2).

Translation:

To translate a point to the right 4 and up 4, we add 4 to the x-coordinate and 4 to the y-coordinate. Therefore, the new coordinates of point C after the translation are (1, 2).

To determine if the image of Triangle ABC is similar or congruent to the original triangle, we need to compare the corresponding sides and angles of both triangles.

Since we performed a rotation of 180°, all the angles in the image triangle are congruent to the corresponding angles in the original triangle. Additionally, since we performed a translation, the sides of the image triangle are congruent to the corresponding sides of the original triangle. Therefore, the image triangle is congruent to the original triangle.

The heat of formation of HC₂H₃O₂ can be found using thermochemical data given. The heat of formation is energy released or absorbed in the formation of compound from its elements in their most stable states.

To calculate the heat of formation for acetic acid (HC₂H₃O₂), the following thermochemical data can be used:

- Heat of formation of carbon (C) = -394.36 kJ/mol

- Heat of formation of hydrogen (H) = +218.79 kJ/mol

- Heat of formation of oxygen (O) = -249.21 kJ/mol

The equation for the heat of formation of acetic acid is as follows:

HF(HC₂H₃O₂) = 2 x (heat of formation of hydrogen) + 1 x (heat of formation of carbon) + 3 x (heat of formation of oxygen)

Plugging in the values, we get:

HF(HC₂H₃O₂)= 2 x 218.79 + 1 x -394.36 + 3 x -249.21

Therefore, the heat of formation of acetic acid is -824.93 kJ/mol.

Carson's work is correct for solving the equations.

Given that;

Carson wants to solve this system of equations.

y = x² + 5x − 6

y = x − 1

Now, We can solve first equation as;

y = x² + 5x - 6

y = x² + 5x - 6 = 0

⇒ x = - 5 ± √5² - 4×1×- 6 / 2

⇒ x = - 5 ± √25 + 24 / 2

⇒ x = - 5 ± √49 / 2

⇒ x = - 5 ± 7/2

⇒ x = - 5 + 7 / 2

⇒ x = 2/2

⇒ x = 1

⇒ x = - 5 - 7 / 2

⇒ x = - 12 / 2

⇒ x = - 6

Hence, From (ii);

⇒ y = x - 1

At x = 1;

y = 1 - 1

y = 0

At x = - 6;

y = - 6 - 1

y = - 7

The unadjusted cost of goods sold for the year is calculated by subtracting the ending inventory from the sum of beginning inventory and purchases. The formula is as follows:

Unadjusted Cost of Goods Sold = Beginning Inventory + Purchases - Ending Inventory

5. Given that the $70,000 ending balance in Work in Process includes $24,000 of direct materials, we can calculate the missing information as follows:

Direct Labor = Total Work in Process - Direct Materials - Overhead
Direct Labor = $70,000 - $24,000 - Overhead

Without knowing the value for overhead, we cannot compute the direct labor cost. However, we can rearrange the formula to solve for overhead:

Overhead = Total Work in Process - Direct Materials - Direct Labor
Overhead = $70,000 - $24,000 - Direct Labor

The mode of the set score is 96

The correct answer is b) The mode of the set score is 96.

The "mean" is the "average" of the set of values.

The "median" is the "middle" value in the list of numbers.

The "mode" is the value that occurs most often.

Now the given scores on 5 Science test are,

96, 7, 82, 96 and 89

So, Sum of all the scores = 96+7+82+96+89= 370

Mean :

Mean = Sum of all the scores / Number of tests

⇒ Mean = 370 / 5

⇒ Mean = 74

Median :

Median is the middle value after rearrangement

So, rearranging the scores we get,

7, 82,) 89,( 96, 96

Hence the median of the scores is 89

Mode :

Mode is the number occurring the most. Since 96 occurs the most, hence the mode is 96.

Answer:

Step-by-step explanation:

To calculate the cost of the cover, we need to know the area of the pool. Assuming that the pool is rectangular and has the dimensions given by the four numbers provided (30, 18, 18, 6), we can calculate the area as follows:

Area = length * width

Area = 30 * 18

Area = 540 square feet

Therefore, the cover for this pool would cost:

Cost = Area * Price per square foot

Cost = 540 * $2.25

Cost = $1,215

So the cover would cost $1,215.

The two combinations that shows that the landscapers work hours and total work fee are proportional are: 3 hours for $105 and 7.5 hours for $262.50(option A and F)

Direct proportion or direct variation is the relation between two quantities where the ratio of the two is equal to a constant value. It is represented by the proportional symbol.

Direct proportion is given by y= kx, where k is the constant and y and x are the variables.

If x represents the landscapers work hours and y represents the total work fee.

y= kx

when y = $140 and x= 4hours

k= 140/4= 35

therefore when x= 3 then y= 3×35=105

similarly when x= 7.5, y= 35×7.5=262.50

Only option A and F obeys the proportional relationship.

Group the Variable's:

2 x - 5 + 7 y - 3 = 9 x - 1 - y -8

2x -9x + 7y +y = -1 -8 +5 + 3

-7x + 8y = -1

From this find x and y
