Answer:

x=12, y=6

Step-by-step explanation:

Very simple!

Just substitute 0 for y and solve for x!

$x+2(0)=12$ (anything times 0 equals 0!)

$x=12$

Now you can do the same thing but substitute 0 for x!

$0+2y=12$

$y=6$

Hope this helps!

If one atom of carbon weighs 1.99 × 10^−22 g and one atom of hydrogen weighs 1.67 × 10^−27 g, which element weighs more? Explain

garik1379 [7]

Answer:

The atom of carbon weighs more

Step-by-step explanation:

we have

<em>Atom of carbon weighs</em>

$1.99*10^{-22}\ g=1.99*10^{-22}(\frac{10^{5}}{10^{5}})=199,000*10^{-22}(\frac{1}{10^{5}})=199,000*10^{-27}\ g$

<em>Atom of hydrogen weighs</em>

$1.67*10^{-27}\ g$

Compare

$199,000*10^{-27}\ g > 1.67*10^{-27}\ g$

therefore

The atom of carbon weighs more

Which of the following is equivalent to (n-3)(n-5) a. n2-8n+15, b. n2+8n-15, c. n2-15n+8

solong [7]

Foil the binomials

First: n*n=n^2
Outer: n*-5=-5n
Inner: -3*n=-3n
Last: -3*-5=15

Put it together and simplify
n^2-5n-3n+15
n^2-8n+15

Final answer: A

Graph the solution to this inequality on the number line.

gladu [14]

Answer: x>8
Subtract 8 from both sides -6x< -48 (40 is a negative so -8 will just add to it)
Divide -48 and -6
X< 8 (since they’re both negative it’ll turn into a positive because we divided)
Turn the <
X>8
