10x - 4y = 5 (if it requires shorten)

Step-by-step explanation:

x + y/5 - 1 = y - x

<=> (5x + y - 1.5)/5 = 5(y - x)/5

<=> 5x + y - 5 = 5y - 5x

<=> 5x + 5x + y - 5y = 5

<=> 10x - 4y = 5

Answer: 119°

∠C + 112° = 180°

⇔ ∠C = 180 - 112 = 68°

because ∠B is the outer angle of the triangle

=> ∠B = ∠C + 51° = 68° + 51° = 119°

Step-by-step explanation:

I’m sorry if it wrong

The function (5n² - 9) / (n + 3) is a natural number for n = 3 and n = 15.

A function is given which is (5n² - 9) / (2n + 6).

We have to find the value of natural number n for which the given function is also natural number.

What do you mean by natural numbers ?

Natural numbers are known as the counting numbers which starts from 1 and end at infinity and also includes the whole numbers excluding 0.

As per the question ;

(5n² - 9) / (2n + 6) is a natural number for the value of n which is also a natural number.

Let's assume ;

(5n² - 9) / (2n + 6) = k

or

(5n² - 9) / (n + 3) = 2k

So , we can say that (5n² - 9) / (n + 3) is an even number.

We know that ;

Dividend ÷ Divisor = Quotient

If we divide (5n² - 9) by (n + 3) we will get ;

Quotient = 5n - 15

and

Remainder = 36

We can write it as ;

(5n² - 9) ÷ (n + 3) = (5n - 15) + {36 / (n+ 3)}

Here ;

36 / (n+ 3) is a natural number and n is a natural number.

Assume ;

n = 1 , 3 , 6 , 9 , 15 , 33

Let's check ;

for n = 1 ;

(5n - 15) + {36 / (n+ 3)} will be ;

= (5 - 15) + {36 / (1+ 3)}

= -1

for n = 3 ;

(5n - 15) + {36 / (n+ 3)} will be ;

= (15 - 15) + {36 / (3+ 3)}

= 6

for n = 6 ;

(5n - 15) + {36 / (n+ 3)} will be ;

= (30 - 15) + {36 / (6+ 3)}

= 19

for n = 9 ;

(5n - 15) + {36 / (n+ 3)} will be ;

= (45 - 15) + {36 / (9+ 3)}

= 33

for n = 15 ;

(5n - 15) + {36 / (n+ 3)} will be ;

= (75 - 15) + {36 / (15+ 3)}

= 62

for n = 33 ;

(5n - 15) + {36 / (n+ 3)} will be ;

= (165 - 15) + {36 / (33+ 3)}

= 151

So , we found that only for values of n = 3 and n = 15 , the value of (5n - 15) + {36 / (n+ 3)} is also an even number.

Thus , the function (5n² - 9) / (n + 3) is a natural number for n = 3 and n = 15.

Step-by-step explanation:

Answer:

k = -1/3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3(k−5)=−16

(3)(k)+(3)(−5)=−16(Distribute)

3k+−15=−16

3k−15=−16

Step 2: Add 15 to both sides.

3k−15+15=−16+15

3k=−1

Step 3: Divide both sides by 3.

3k /3 = −1 /3

k =  −1 /3

The angle by which turns counterclockwise about point P to coincide with is 180 degree angle

What is 180 degree angle?

The angle which forms a straight line is called the 180-degree angle. A 180-degree angle is a straight angle and it is exactly half of a revolution. The two arms of the angle which are making 180-degree are just opposite to each other from the common vertex.

The points D, P and C forms a straight line.

So, if it turns clockwise about Point P, it would make an angle of 180 degree.

as the point D and C are of equal lengths and opposite to each other, the angle from P turning clockwise makes 180 degree angle.

Answer:11

Step-by-step explanation:

18*1/3+5=11

Answer:

11

Step-by-step explanation:

To find the number that is 5 more than [tex]\frac{1}{3}[/tex] of 18, we can start by evaluating what [tex]\frac{1}{3}[/tex]  is:

[tex]\frac{1}{3}[/tex]  of 18

⇒ [tex]\frac{1}{3} \times 18[/tex]

To multiply a whole number by a fraction, we can convert the whole number into a fraction by giving it a denominator of 1:

⇒ [tex]\frac{1}{3} \times \frac{18}{1}[/tex]

⇒ [tex]\frac{18}{3}[/tex]   [This is the same as 18 ÷ 3]

⇒ [tex]\bf 6[/tex]

Now that we have the value of [tex]\frac{1}{3}[/tex] of 18, we can simply add to it to find the number that is 5 more than [tex]\frac{1}{3}[/tex] of 18:

[tex](\frac{1}{3} \times 18) + 5[/tex]

⇒ [tex]6 + 5[/tex]

⇒ [tex]\bf 11[/tex]

∴ The number we are looking for is 11.

Pythagorean theorem states that for a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

We can apply this theorem only in a right triangle.

Example:

The hypotenuse side of a triangle with the two sides as 4 cm and 3 cm.

Hypotenuse side = √(4² + 3²) = √(16 + 9) = √25 = 5 cm

We have,

From ΔRMN,

NM² = RN² + RM²

8² = y² + x²

64 = y² + x² ______(1)

And,

From ΔRNS,

RN² = RS² + SN²

y² = z² + 6²

y² = z² + 36 ______(2)

And,

From ΔRMS,

x² = z² + 2²

x² = z² + 4 _______(3)

From (1), (2), and (3).

x² = y² - 36 + 4

x² = 64 - x² - 36 + 4

2x² = 64 - 36 + 4

2x² = 68 - 36

2x² = 32

x² = 16

x = 4

Thus,

The value of x is 4.

Answer:

(3p + 5)^2

Step-by-step explanation:

9p^2 + 30p + 25

9p^2 is the square of 3p = a

25 is the square of 5 = b

This may be the square of a binomial.

We need to check the middle term.

(a + b)^2 = a^2 + 2ab + b^2

2ab = 2(3p)(5) = 30p

This is the square of a binomial.

9p^2 + 30p + 25 = (3p + 5)^2

The car is at 60ft from you 5 seconds after it starts moving and 7.5 seconds after it starts moving.

The 48*t part means the number of feet that the car moves in t seconds

We know that the absolute value equation that models the distance is:

d(t) = |300 - 48*t|

Then what we need to solve is d(t) = 60, this is:

d(t) = 60 = |300 - 48*t|

That absolute value equation can be represented in two forms:

300 - 48*t = 60

300 - 48*t = -60

Solving these two we get the two times at which the car is at 60ft from you.

-48*t = 60 - 300

t = (60 - 300)/(-48)  = 5

t = (-60 - 300)/(-48) = 7.5

So the car is at 60ft from you 5 seconds after it starts moving and 7.5 seconds after it starts moving.

The 48*t part means the number of feet that the car moves in t seconds.

1). Let the length of a marathon race = x miles

   Marathon runner runs this race in the sequence formed as,

  Common ratio = [tex]\frac{\frac{x}{4}}{\frac{x}{2}}[/tex]

  It's not a geometric sequence.
