Answer:

(x - 1)(3x - 5)

Step-by-step explanation:

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x-term.

product = 3 × 5 = 15 and sum = - 8

The factors are - 3 and - 5

use these factors to split the middle term

3x² - 3x - 5x + 5 ( factor the first/second and third/fourth terms )

= 3x(x - 1) - 5(x - 1) ( take out the common factor (x - 1) )

= (x - 1)(3x - 5)

Answer:

(x - 1)(3x - 5)

Answer:

Step-by-step explanation:

I am assuming this is meant to say 9/10 and 36/40.

If so 9/10=36/40.

Because 10 x 4 = 40

and 9 x 4 = 36.

In 2 hours 50 City blocks will be covered.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Five city blocks covered = 12 minutes

So, in one minutes the blocks covered = 5/12

Then, to walk 2 hours the number of block covered

= 120 x 5 /12

= 5 x  10

= 50 blocks

Step-by-step explanation:

We have three conditions

(1) 5P = 3S

(2)  S = C + 0.30

(3)  P = C – 0.20                           Substitute (3) into (1)

Answer:

4 = y

Step-by-step explanation:

2y+16=4y+8

The first step is to subtract 2y from each side.

2y-2y+16=4y-2y+8

16 = 2y+8

Now subtract 8 from each side

16-8 = 2y+8-8

8 = 2y

Now divide each side by 2

8/2 = 2y/2

4 = y

The formula for the side length of 3 inches is P = 5s; 15 inches. So option (a) is correct.

To find the perimeter of a regular pentagon, we can use the formula:  P = 5s , where  P  is the perimeter and  s  is the length of a side.

Let's evaluate this formula for a side length of 3 inches:

P = 5s

P = 5 x 3

P = 15

So, the perimeter of the pentagon with a side length of 3 inches is 15 inches.

The correct option is (a) ( P = 5s; 15)  inches.

To find the perimeter of a regular pentagon, multiply the number of sides (5) by the length of one side.

To find the formula for the perimeter of a regular pentagon in terms of the length of a side, let's first understand the properties of a regular pentagon. A regular pentagon is a polygon with five equal sides and five equal angles.

The perimeter of any polygon is the sum of the lengths of all its sides. Since a regular pentagon has five equal sides, we can express its perimeter as the product of the number of sides (5) and the length of one side (s). Therefore, the formula for the perimeter [tex](\( P \)) of a regular pentagon in terms of the length of a side (\( s \)) is \( P = 5s \).[/tex]

Now, to evaluate the formula for a side length of 3 inches, we substitute  [tex]\( s = 3 \) into the formula:[/tex]

[tex]\[ P = 5 \times 3 = 15 \text{ inches} \][/tex]

This means that the perimeter of the regular pentagon with a side length of 3 inches is 15 inches.

Therefore, the correct answer is option a: [tex]\( P = 5s; 15 \text{ inches} \).[/tex]

This solution provides a clear explanation of how to derive the formula for the perimeter of a regular pentagon and how to evaluate it for a specific side length.

Answer:depending on what type of equation but ussuming in standard form it is Ax+By+c

Step-by-step explanation:

To rearrange an equation, balance operations on both sides to isolate a specific variable, maintain units, use calculators correctly, and always check the solution by substituting back into the original equation.

Rearranging an equation involves moving terms from one side of the equation to the other to isolate a specific variable. This process is guided by the principle of balance, which means whatever operations you do to one side of the equation, you must do to the other side to keep the equation balanced. For instance, if you need to move a constant to the opposite side, you would add or subtract it from both sides.

Steps to Rearrange an Equation

For example, while dealing with chemical equations, you'll often need to rearrange the formulas for reactants and products to balance the equation.

Answer:

x = 55

Step-by-step explanation:

the sum of the 3 angles in a triangle = 180°

the sum of the 4 angles in a quadrilateral = 360°

the angles to the left and above 130° angle = 50°

Since 130° and 50° form a straight angle and are supplementary

the third angle in the left triangle = 180° - (50 + 30)° = 100°

thus the angle to the right = 180° - 100° = 80°  ( straight angle )

the third angle in the upper triangle = 180° - (50 + 45)° = 85°

the angle below it = 180° - 85° = 95° ( straight angle )

We now have 3 angles inside the quadrilateral of 130°, 80° and 95°

x = 360° - (130 + 80 + 95)° = 55

Answer:

h = 1558.8

Step-by-step explanation:

Let x be the distance from the vertex of the 30 degree angle to the base of Blue mountain.

Tan (30) = h/x                       Multiply both sides by x.

x * Tan(30) = h

Tan(25) = h/(x + 200)           Multiply x + 200 on both sides.

(x + 200) * Tan(25) = h

Now you have 2 equations both equal to h. The two sides can be equated to each other.

x*tan(30)  = (x + h) * Tan(25)         Divide both sides by tan(25)

x*tan(30)/tan(25) = x + 200          Find Tan(30)/Tan(25)

Tan30 / tan(25) = 1.23813 so

1.23813 x = x  + 200                      Subtract x from both sides.

0.23813x = 200                             Divide both sides by 0.23813

x = 200/0.23813

x = 839.99

================

That is not the answer you have been asked for. What you need is h.

Tan(30) = x / h                                Multiply both sides by h

h*tan(30) = x                                   Divide both sides by tan(30)

h = x/tan(30)

h = 839.99/tan(30)                        Tan 30 = 0.57735

h = 839.99/0.57735

h = 1558.8
