Answer: Its D

Step-by-step explanation:

Thank me later.

Answer:

D

Step-by-step explanation:

4x - 12 - x  ≥ 3

Add 12 to both sides.

4x - x ≥ 15

Subtract x (or 1x) from 4x

4x - x = 3x

3x ≥ 15

Divide both sides by 3.

x ≥ 5

Answers

Solution:

[tex]\text G\text i\text v\text e\text n\ \text e\text x\text p\text r\text e\text s\text s\text i\text o\text n: 20x^{3} + 34x^{2} + 6x[/tex]

Step-1: Find the GCF of the terms.

[tex]20x^{3} \ \ \ = \ \ \ 2 \times 2 \times 5 \times x \times x \times x \\34x^{2} \ \ \ = \ \ \ 2 \times 17 \times x \times x \\ 6x \ \ \ \ \ \ = \ \ \ 2 \times 3 \times x[/tex]

GCF = 2x

Step-2: Factor the expression using the GCF.

[tex]20x^{3} + 34x^{2} + 6x \\\\ {2x(10x^{2} + 17x + 3)}[/tex]

Step-3: Further factorize.

[tex]{2x(10x^{2} + 17x + 3)}[/tex]

[tex]2x(2x + 3)(5x + 1)[/tex]

Thus, the factorized expression is [tex]2x(2x + 3)(5x + 1)[/tex].

The solutions of the given linear equations are:  x = 7, - 13; x = 6, - 7; x = 5, - 9, respectively.

What is a linear equation?

A linear equation is an equation that has on or multiple variables with the highest power of the variable is 1.

Given equations are:

1. |3x + 9| = 30

⇒ ( |3x + 9| )² = (30)²

⇒ 9x² + 54x + 81 = 900

⇒ 9x² + 54x + 81 - 900 = 0

⇒ 9x² + 54x - 819 = 0

⇒ 9(x² + 6x - 91) = 0

⇒ (x² + 6x - 91) = 0

⇒ (x + 13)(x - 7) = 0

⇒ x = 7, - 13

2. |2x+1| = - 13

⇒ (|2x+1|)² = (- 13)²

⇒ 4x² + 4x + 1 = 169

⇒ 4x² + 4x - 168 = 0

⇒ 4(x² + x - 42)= 0

⇒ (x² + x - 42)= 0

⇒(x - 6)(x + 7) = 0

⇒ x = 6, - 7

3. |x + 2| + 4 = 11

⇒ |x + 2| = 7

⇒ (|x + 2|)² = 7²

⇒ x² + 4x + 4 = 49

⇒ x² + 4x - 45 = 0

⇒ (x - 5)(x + 9) = 0

⇒ x = 5, - 9

Jack Talon rolled 82 barrels onto the ship's
deck. 50% of those barrels were empty. How
many empty barrels did Jack roll onto the
ship's deck?

Answers

Answer:

41

Step-by-step explanation:

You do 50% of 82 which is 41.

Answer: 41 empty barrels

Step-by-step explanation:

if Jack rolled 82 total barrels and 50% of them were empty, that is the same as taking 82 times .5, which gives us 41. This is how we know he rolled 41 empty barrels onto the ships deck.

A path 5m wide runs along inside a rectangular field. The length of the rectangular field is three times the breadth of the field. if the area of the path is 500m2, then find the length and breadth of the field..

Answers

Answer:

Length = 45m

Breadth = 15m

Step-by-step explanation:

Dimensions of Rectangular field:

Let the breadth (B)=BC = x m

Length (L) = AB = 3x m

width of the road (w) = 5 m

Dimensions of inner rectangle:

length (l) = EF = L-2w

= 3x - 2×5

= (3x-10) m

breadth (b)=EH = B-2w

= (x-10) m

Given ,

Area of the path =500 m²

=> Area of ABCD - Area of EFGH = 500

=> L×B - l×b=500

=> (3x)× x - (3x-10)(x-10)=500

=> 3x²-(3x²-30x-10x+100)=500

=> 3x²-3x²+30x+10x-100=500

=> 40x=500+100

=> 40x = 600

=> x = 600/40

=> x = 15

Therefore,

Length (L) = 3x = 3×15 = 45m

Breadth (B) = x = 15m

1/5 divided by -1/14?

Answers

Answer:

-2.8 or -14/5

Step-by-step explanation:

To divide one fraction by another, there is a really cool method called Keep Change Flip

Keep the first fraction

Change the division sign to multiplication

Flip the numbers on the last fraction

Let's try it out.

Keep the 1/5

Change the ÷ to a ×

Flip the -1/14 to a -14/1

1/5 × -14/1

Multiply the top numbers by each other first

1 × -14 = -14

Now the bottom numbers

5 × -1 = -5

The fraction we have now is -14/5

It can also be written as -2.8

If the circle has a diameter of 2 inches, then it has a circumference of 6.28 inches.

Answers

Answer:

True, the diameter=2in and the circumference=6.28

Step-by-step explanation:

The circumference, C, of a circle is found by the following equation: C = 2 x pi x r where r equals the radius of the circle (or half its diameter) and pi = 3.14159 (a constant).

Thus, 6.28 = 2 x pi x r

Solving for r: 6.28/(2 x pi) = r

or: 6.28/(2 x 3.14) = 6.28/6.28 = r

thus r = 1 and since the diameter equals 2 x r, the diameter is 2.
