In the equation 3x+3y+3z=18 what does x equal

1 answer:

5 0

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

Which number is greater than the absolute value of -3/8? -5/8 -1/8 1/4 0.5

erica [24]

-3/8 = -0.375

-5/8 = -0.625
-1/8 = -0.125
1/4 = 0.25
0.5 = 0.5

Therefore 1/4 & 0.5 & -1/8 > -3/8

Simplify. x/4x+x^2

djyliett [7]

$\bf \cfrac{x}{4x+x^2}\implies \cfrac{\begin{matrix} x \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}}{\begin{matrix} x \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~(4+x)}\implies \cfrac{1}{4+x}\qquad \{x|x\in \mathbb{R}, x\ne -4\}$

if you're wondering about the restriction of x ≠ -4, is due to that would make the fraction with a denominator of 0 and thus undefined.
