Answer:

x=31

Step-by-step explanation:

2x+4x-6=180

6x=180+6

6x=186

x=31

Answer:

x = 31

Step-by-step explanation:

2x and 4x - 6 are alternate angles and supplementary, sum to 180°, then

2x + 4x - 6 = 180

6x - 6 = 180 ( add 6 to both sides )

6x = 186 ( divide both sides by 6 )

x = 31

Answer:

6 and 15

Step-by-step explanation:

x^2 + 9x = x^2 + 7x +12

2x = 12

x = 6

The dimension of the original rectangles are 6 inche and 15 inches.

A rectangle is a two-dimensional shape where the length and width are different.

The area of a rectangle is given as:

Area = Length x width

We have,

Original rectangle:

Length = x + 9

Width = x

Area = (x + 9)x

New rectangle:

Length = (x + 9) - 5 = x + 4

Width = x + 3

Area = (x + 4)(x + 3)

Now,

(x + 9)x = (x + 4)(x + 3)

x² + 9x = x² + 3x + 4x + 12

9x = 7x + 12

9x - 7x = 12

2x = 12

x = 6

Now,

The dimension of the original rectangle.

x + 9 = 6 + 9 = 15

x = 6

Thus,

The dimensions of the rectangles are 6 inches and 15. inches

Answer:

m(∠KJL) = 54°

Step-by-step explanation:

It's given that two sides of ΔJKL are equal in measure.

Therefore, angles opposite to the equal sides will be equal.

By triangle sum theorem in ΔJKL,

m∠KJL + m∠KLJ + m∠JKL = 180°

2(m∠KJL) + 72° = 180°

2(m∠KJL) = 180° - 72°

m∠KJL = [tex]\frac{108}{2}[/tex]

m(∠KJL) = 54°

Answer:   y = f(x - 4) - 1, lower left corner

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

Explanation:

Let's focus on only the left-most points of each curve

For the black semicircle, the left-most point is located at (-7,0). The corresponding point on the red semicircle is at (-3,-1)

To go from (-7,0) to (-3,-1), we will do two things

This can be done in any order. The action of "shift 4 units to the right" is effectively the same as shifting the xy axis 4 units to the left while keeping the curves fixed in place. This gives the illusion of movement. When we shift 4 the xy axis 4 units to the left, we're replacing each x input with x-4 as the new input.

In short, we go from f(x) to f(x-4). This is why we have this opposite motion going on.

The up and down motion is fairly straight forward. To shift 1 unit down, we subtract off 1. This is to subtract 1 from the y coordinate.

Overall, we go from y = f(x) to y = f(x - 4) - 1

Applying this transformation will move (-7,0) to (-3,-1) as described above. It will also move every other point on the black curve to their new corresponding location on the red curve.

Answer:

90°

Answer:

5%

Step-by-step explanation:

Solving our equation

r = 4537.5 / ( 9075 × 10 ) = 0.05

r = 0.05

converting r decimal to a percentage

R = 0.05 * 100 = 5%/year

The interest rate required to

accumulate simple interest of $ 4,537.50

from a principal of $ 9,075.00

Answer: The part of the bulletin board has artwork or math papers [tex]=\dfrac35[/tex]

Step-by-step explanation:

Given: Part of bulletin board has artwork = [tex]\dfrac{2}{5}[/tex]

Part of bulletin board has math papers = [tex]\dfrac{1}{5}[/tex]

The part of the bulletin board has artwork or math papers = [tex]\dfrac25+\dfrac15[/tex]

[tex]=\dfrac35[/tex]

Hence, the part of the bulletin board has artwork or math papers [tex]=\dfrac35[/tex]

Answer:

5400

Step-by-step explanation:

Given data

P= 5000

r= 8%

t= 1 year

The simple interest expression is given as

A= P(1+rt)

Required

The final amount A

substitute

A= 5000(1+0.08*1)

A= 5000*1.08

A= 5400

Hence the final amount 5400

Simplifying

3m = 5(m + 3) + -3

Reorder the terms:

3m = 5(3 + m) + -3

3m = (3 * 5 + m * 5) + -3

3m = (15 + 5m) + -3

Reorder the terms:

3m = 15 + -3 + 5m

Combine like terms: 15 + -3 = 12

3m = 12 + 5m

Solving

3m = 12 + 5m

Solving for variable 'm'.

Move all terms containing m to the left, all other terms to the right.

Add '-5m' to each side of the equation.

3m + -5m = 12 + 5m + -5m

Combine like terms: 3m + -5m = -2m

-2m = 12 + 5m + -5m

Combine like terms: 5m + -5m = 0

-2m = 12 + 0

-2m = 12

Divide each side by '-2'.

m = -6

Simplifying

m = -6

3m=5(m+3)-3  can be solved to get m=-6

An equation is a mathematical statement that shows that two mathematical expressions are equal. Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows: Expression: (Math Operator, Number/Variable, Math Operator)

3m=5(m+3)-3, This can be solved by following the steps mentioned below:

On solving parenthesis

3m=5m+15-3

3m=5m+12

Transposing like terms together,

3m-5m=12

-2m=12

Dividing both sides by -2

-2m/-2=12/-2

m=-6

So, m=-6 for given equation 3m=5(m+3)-3

2) Volume of the cylinder is calculated with its height and bottom area.
