Step-by-step explanation:

$( - 4) + ( - 8) - ( - 3) + ( + 6) - ( + 10) \\ = ( - 4) - 8 + 3 + 6 - 10 \\ = - 12 + 3 + 6 - 10 \\ = - 9 + 6 - 10 \\ = - 3 - 10 \\ = - 13$

What is the solution of the system?

Kryger [21]

Greetings!

Solve the System, using Elimination:
$\left \{ {{4x+2y=18} \atop {2x+3y=15}} \right.$

Multiply Equation #2 by 2:
$\left \{ {{4x+2y=18} \atop {2(2x+3y)=2(15)}} \right.$

$\left \{ {{4x+2y=18} \atop {4x+6y=30}} \right.$

Eliminate variable x:
$-\frac{ \left \{ {{4x+2y=18} \atop {4x+6y=30}} \right.}{0x-4y=-12}$

$4y=-12$

Divide both sides by 4:
$\frac{4y}{4}= \frac{12}{4}$

$y=3$

Input this value into one of the Equations:
$4x+2y=18$

$4x+2(3)=18$

Simplify:
$4x+6=18$

$(4x+6)+(-6)=(18)+(-6)$

$4x=12$

Divide both sides by 4.
$\frac{4x}{4}= \frac{12}{4}$

$x=3$

The Solution to this System (The Point of Intersection):
$\boxed{(3,3)}$

I hope this helped!

The land area of the earth is 57,505,708 square miles. To the nearest tenth, how much longer is the land of Asia than North Amer

Leokris [45]

Answer:

57,505,708 x .165 =9488441.82 NA

57,505,708 x .3 = 17251712.4 Asia

17251712.4 - 9488441.82 = 7763270.58

That's how much larger asia is than north america
