What is 1,711,239 rounded to the nearest hundred?
Elina [12.6K]
The hundreds place is filled by a 2.

The number next to it is a 3, which tells how to round. A 3 says 'stay' with the 2. The remaining places after it become zeros.

-3x-y=-17 4x + 2 y equals 20
ExtremeBDS [4]
-3x - y = -17
4x + 2y = 20

multiply one part of the equation so that we can be able to use the process of elimination.

(-3x - y = -17)2
4x + 2y = 20

Now we have:

-6x -2y = - 34
4x+2y= 20
------------------------
-2x = -14

Divide -2 on both sides.

-2x = -14
/-2       /-2

x = -7.


=============================================

To solve for y, we just have to substitute the value of x to any of the equation given above, that we feel comfortable with. And I'm going to choose this equation: 4x + 2y = 20


4x + 2y = 20

4(-7) + 2y = 20

-28 + 2y = 20

Add 28 on both sides

-28 + 2y = 20
+28          +28
---------------------
2y = 48
/2      /2

y = 24.


The last thing you would do is to check if the answers is correct.
All you have to do is plug in the values of x and y into both equations and see if they equal to one another.

You may have to do this by yourself :P

Anyways, if you have any questions about this topic, feel free to PM me or any other users interested. Thank you for being part of Brainly! Have a nice day!

Someone please help me !!! i need it by 7:30!! ammm!!!

Answer:

LON and MLN are both equal to 126 degrees,

since the angles with the value '4x + 7' and '7x - 35' degrees are equal to each other, you can rewrite it like this:

4x+7=7x-35

now, take the 7x away from both sides:

-3x+7=-35

then, subtract 7 from both sides:

-3x=-42

now, divide both sides by -3:

x=14

now that we know the value of x (14), we can plug it into the expressions.

4(14)+7=63

7(14)=63

add them together to find the angle MLN

and since the opposite angle (LON) is equal to MLN, they both = 126 degrees

hope this helped :)
