The answer is C. Just took the quiz and B was wrong. It needs to be the one with the smaller 12.
Answer:
Neon is stable, hence has no charge.
Oxide (O2-) has a charge of -2
Cooper (Cu2+) has a charge of +2
Tin (Sn2+) has a charge of +2
hence overall charge = -2+2+2
<em><u>Over</u></em><em><u>all</u></em><em><u> </u></em><em><u>charge</u></em><em><u> </u></em>= +2
That's unusual: repetition: -1/2 - 1/2.
Did you perhaps mean "Factor -1/2 out of (-1/2)x + 6?
Let's do that. Let's rewrite 6 as (-1/2)(-12).
Then (-1/2)x + 6 (-1/2)x -(1/2)(-12)
-------------- = ------------------------ = x - 1/2
-1/2 -1/2
Hope that's what you wanted. If not, please try to apply a similar approach to solving this particular problem.
Answer:
C
Step-by-step explanation:
16 + 4x = 10 + 14
16 + 4x = 24.
4x = 24 - 16
4x = 8
x = 8 ÷ 4
x = 2
8x = 2 × 8
8x = 16
Final answer = 16.
