<span>3x+3y+3z=18 

Start by subtracting both sides by 3z

3x + 3y = 18 - 3z 

Now , you can subtract 3y from both sides....

3x = - 3z - 3y + 18 

Finally .... To get x by itself divide both sides by 3.......

x = - z - y + 6 is the answer</span>

Whats the square root of 39 to the nearest integer
soldi70 [24.7K]

Answer:

To the nearest integer, the square root of 39 would be 6.

Step-by-step explanation:

To find the answer, look at the perfect squares on either side of 39. Lower than it would be 36 and the next highest would be 49. Since it is closer to 36, we can estimate that the answer is 6.
