Answer:
A
Step-by-step explanation:
The additive inverse property states that if we have a number a, then:

Here, we have the equation:

And we divide both sides by 2:

To acquire:

So, we did <em>not</em> use the additive inverse property since we didn't add anything.
Instead, we used the<em> division property of equality</em> by dividing both sides by 2.
So, our answer is A.
And we're done!
Answer:
1.375 or 1/38
Step-by-step explanation:
(3/8+2/3)+1/3
(1.04166666667)+1/3
1.375 or 1 3/8
Three and a half divided by seven-eighth equals seven over two times eight over seven equals fifty over fourteen equals four
<span>8 - 1/3x = 16
</span>⇒ -1/3x= 16-8
⇒ -1/3x= 8
⇒ x= -24
The final answer is -24~
Subtract the second equation from double the first equation:
2x+6y-2x-(-4y)=0
10y=0
Therefore, y=0. Substituting this into the first equation, we see that:
x+3(0)=3
x=3
Therefore, x=3. The solution to this system is x=3, y=0, or (3, 0).
