Answer: 1430

Step-by-step explanation: x + y + z = 2680  

x = 2z - 100  

y = 3z + 80  

x + y = 5z - 20  

6z - 20 = 2680  

z = 450  

y = 1430  

Solution:  

x = 800, y = 1430, z = 450

What is the value of x in the following equation? -3x-2=2x+8
Arlecino [84]

Answer:

-2 =x

Step-by-step explanation:

-3x-2=2x+8

Add 3x to each side

-3x+3x-2=2x+3x+8

-2 = 5x+8

Subtract 8 from each side

-2-8 = 5x+8-8

-10 = 5x

Divide by 5

-10/5 = 5x/5

-2 =x

What is the value of x in <br> 150-35x=45
Annette [7]
Your answer is x = 3 because if you take 150 and subtract it by both sides: 
 150 - 35x = 45
-150           -150

you have to cross out both 150 and -150, take 45 and subtract 150 which will give you -105. 
  -35x = -105 

take -35 and divide by both sides. Cross out the two -35's. Take -105/-35 which your answer is x = 3. Hopes this helps. :)

What is the area of georgina rounded to the nearest mile 59,424.77
AleksAgata [21]
<h2>Answer:  </h2>

59,425 sq mi  

<h2>Step-by-step explanation:  </h2>

When you want to round to the units place, you look at the digit in the number that is in the place to the right of that: the tenths place. Here, that digit is 7, which is more than 4. Because that digit is more than 4, 1 is added to the units place and all the digits to the right of that are dropped.  

This gives you 59,424 +1 = 59,425.    

If the tenths digit were 4 or less, no change would be made to values in the units place or to the left of that. The tenths digit and digits to the right would be dropped.  

... 59,424.3 ⇒ 59,424 . . . . . for example
