The equation given in the question has to be answered to the nearest tenth. The only thing that one should be careful about is the cross multiplication part. Other than that there is no difficulty in the given problem. Now let us get down to the equation in the question.
15/30 = n/34
30 * n = 15 * 34
30n = 510
n = 510/30
   = 51/3
   = 17
So the value of the unknown variable "n" comes out to be 17.

15/30= n/34
⇒ (15/15) / (30/15)= n/34
⇒ 1/2= n/34

Cross multiply:
2*n= 34*1
⇒ n= 34*1/2= 17

Rounded to the nearest tenth, the final answer is n=17.0~

o-na [289]

Answer: it could end in 20 different ways.

Step-by-step explanation:

This match could be

3x0 D or F

3x1 D or F

3x2 D or F

For 3x0

We have 2 options: DDD or FFF

2.P₁ = 2.1 = 2

For 3x1

We have 6 options

DFDD         FDFF

DDFD         FFDF    

FDDD         DFFF

2.3.1 = 6

For 3x2

we have 12 options:

DFDFD          FDFDF

DDFFD          FFDDF

DFFDD          FDDFF

FFDDD          DDFFF

FDFDD          DFDFF

FDDFD          DFFDF

2.3.2 = 12

In total we could have 20 outcomes.

Answer:

1.- If a number can be written or can be converted to p/q form, where p and q are integers and q is a non-zero number, then it is said to be rational and if it cannot be written in this form, then it is irrational.

2.- The square root of a number is that number which when multiplied by itself two times gives us that number.

Example:

Let us use the square root of 64.

√64 = x , so that (x)(x) = 64

We know that, (8)(8) = 64

∴ √64 = 8

The cube root of a number is that number which when multiplied by itself three times gives us that number.

Example:

Let us use the square root of 64

∛64 = x , so that (x)(x)(x) = 64 ,

We know that, 4 x 4 x 4 = 64

∴ ∛64 = 4

Use the subtraction method to solve the system of equations. Choose the correct ordered pair. 2x-y=6
Ber [7]

Answer:

Check for (3, 0)

Put x = 3 and y = 0 in equation 2x – y = 6

2(3) – (0) = 6

6 = 6

<h2>True statement. </h2>

(3,0) is a solution of 2x – y = 6.

(ii) Check for (0, 6)

Put x = 0 and y = 6 in 2x – y = 6

2 x 0 – 6 = 6-6 = 6

<h2>False statement. </h2>

⇒ (0, 6) is not a solution of 2x – y = 6.

(iii) Check for (2, -2)

Put x = 0 and y = 6 in 2x – y = 6

2 x 2 – (-2) = 6

4 + 2 = 6

6 = 6

<h2>True statement. </h2>

⇒ (2,-2) is a solution of 2x – y = 6.

(iv) Check for (√3, 0)

Put x = √3 and y = 0 in 2x – y = 6

2 x √3 – 0 = 6

2√3 = 6

<h2>False statement. </h2>

⇒(√3, 0) is not a solution of 2x – y = 6.

(v) Check for (1/2, -5)

Put x = 1/2 and y = -5 in 2x – y = 6

2 x (1/2) – (-5) = 6

1 + 5 = 6

6 = 6

<h2>True statement. </h2>

⇒ (1/2, -5) is a solution of 2x – y = 6.

Step-by-step explanation:

Hope it is helpful......
