Before the industrial revolution in 1800 the concentration of carbon in Earth’s atmo- sphere was 280 ppm. The concentration in 2

slega [8]

Answer: There is increase of 4.255 in the amount of carbon in the atmosphere.

Step-by-step explanation:

Since we have given that

Concentration of carbon in Earth's atmosphere in 1800 = 280 ppm

Concentration of carbon in Earth's atmosphere in 2015 = 399 ppm

We need to find the percentage increase in the amount of carbon in the atmosphere.

So, Difference = 399-280 = 119 ppm

so, percentage increase in the amount of carbon is given by

$\dfrac{Difference}{Original}\times 100\\\\=\dfrac{119}{280}\times 100\\\\=\dfrac{11900}{280}\\\\=42.5\%$

Hence, there is increase of 4.255 in the amount of carbon in the atmosphere.

The sum of two numbers is 2. The sum of three times the larger and twice the smaller is 14. Find the numbers.

anzhelika [568]

For this case we have to:

x: Be the variable that represents the largest number

y: Be the variable that represents the smallest number

We propose a system of equations:

$x + y = 2\\3x + 2y = 14$

From the first equation we have to:

$x = 2-y$

Substituting in the second equation:

$3 (2-y) + 2y = 14\\6-3y + 2y = 14\\6-y = 14\\-y = 14-6\\-y = 8\\y = -8$

We look for the value of "x":

$x = 2 - (- 8)\\x = 2 + 8\\x = 10$

Answer: $x = 10\\y = -8$

I really need some help

earnstyle [38]

Answer:

CEFA

Step-by-step explanation:

1. $p=2(2x)+2(3x+2)=4x+6x+4=10x+4$

2. $p=2(x)+2(4x+1)=2x+8x+2=10x+2$

3. $p=2(7)+2(x+5)=14+2x+10=2x+24$

4. $p=2(5)+2(4x-3)=10+8x-6=8x+4$

Hope this helps
