1.1. Which statement explains why the two systems of equations below have the
pochemuha

Answer:

Correct Answer is B. The first equation in B is the sum of the equations in A, while the other is obtained  by multiplying the first equation in A by 2.

Step-by-step explanation:

As given,

A : 6x + 8y = -10     .......equation (1)

     2x - 5y = 12      .......equation (2)

B : 8x + 3y = 2         .......equation (1)

  12x + 16y = - 20    .......equation (1)

Correct Answer is B. The first equation in B is the sum of the equations in A, while the other is obtained  by multiplying the first equation in A by 2.

Proof :

The first part says that ,

Sum of equation (1) of A and equation (2) of A = Equation (1) of B

Firstly , find the Sum of equation (1) of A and equation (2) of A

⇒6x + 8y + 2x - 5y = -10 + 12

⇒8x + 3y = 2

this is same as equation (1) of B

So, it satisfies the first part

The second part says that,

The equation (2) of B is obtained by multiplying the first equation in A by 2.

It means , if the equation (1) is multiplied by 2 = equation (2) of B

Firstly , if the equation (1) is multiplied by 2 , we get

2 ( 6x + 8y = -10 )

⇒ 2 ( 6x + 8y ) = 2 ( -10)

⇒ 12x + 16y = -20

this is same as equation (2) of B

So, it satisfies the second part.

sattari [20]

Answer:

Weight of empty box =  680 gram

Step-by-step explanation:

Given:

Number of noodle = 6 dozen = 12(6) = 72

Weight of each noodle in each packet = 175 gram

Weight of each packet = 10 gram

Total weight = 14 kg = 14,000 gram

Find:

Weight of empty box

Computation:

Total weight of noodle = 72(175) + 72(10)

Total weight of noodle = 13,320 gram

Weight of empty box = Total weight  - Total weight of noodle

Weight of empty box = 14,000 - 13,320

Weight of empty box =  680 gram

Well the digit in the thousands place is about 100 times than the digit in the tens place. 
So 5,000> 50
The digit in the thousands place is more than the digit in the tens place.
