HELP PLEASE someone its importent

elena-s [515]

Answer:

Step-by-step explanation:

Expression on the board :

$12.2x + 50.6 y + 3(1.4x - 2.6y)\\\\= 12.2x + 50.6y + 4.2x - 7.8y\\\\= 16.4x + 42.8y$

Expression by the student :

Expression 1 :

$4 ( 4.1x + 10.7 y ) \\\\= ( 4 \times 4.1x ) + ( 4 \times 10.7 y)\\\\= 16.4x + 42.8y\\\\$

The expression 1 is equivalent to the expression on the board. Because the coefficients of x and y are same on both.

Expression 2 :

$2 ( 6.1x + 25.3 y + 2.1x -3.9y)\\\\= 2 ( 8.2x + 21.4y)\\\\=( 2 \times 8.2x ) + (2 \times 21.4y)\\\\= 16.4x + 42.8y$

The expression 2 is also equivalent to the expression on the board. Because the coefficients of x and y are the same.

Two percent of Jennie’s skin cells were burned when she escaped from a fire. If 3.7×10^10 of her skin cells were burned then, ho

gulaghasi [49]

$1813\times10^9$ cells were not burnt when Jennie escaped from the fire.

Solution:

Given:

2% of skin cells were burnt i.e, $3.7\times10^{10}$ of skin cells were burnt.

To find:

Number of skin cells that were not burnt

We can write $3.7\times10^{10} \text{ as } 37\times10^{9}$

Therefore, by equating the values we get,

2% of the cell is $37\times10^9$

1% of the cell is $\frac{37\times10^9}{3}=18.5\times10^9$

As, 1% of the cell is $18.5\times10^9$

98% of the cell will be $98\times18.5\times10^9=1813\times10^9$

$\therefore \text{ skin cells that are not burnt is } 1813\times10^9$

4 consecutive integers add up to 34. Write an equation to find the numbers

Kisachek [45]

Answer:

$(n+(n+1)+(n+2)+(n+3))=34$

Step-by-step explanation:

$(n+(n+1)+(n+2)+(n+3))=34$

To make them consecutive, means they have to be one after the other.
You assume one of the numbers are n, to make the other integers consecutive you add 1 then 2 then 3.
