Just plug in the numbers:

4:  16 + 24 = 40  YES

5 = 25 + 40 ≠ 40 NO

8: 64 + 48 ≠ 40 NO

10: 100 + 60 ≠ 40 NO


So A. is the correct answer. Just to be sure:

-10: 100 + ( - 60) = 40

Solve for w.<br> 2w=12-4w<br> Simplify your answer as much as possible.
aev [14]
So we have an equation:
2w=12-4w
Firstly, let's simplify, and divide all terms by 2:
w=6-2w
Now, we add 2w over to the other side:
3w=6
And finally, we divide both sides by 3:
w=2
Hope this helps!

diamong [38]

Answer:

The expression x-0.3x represents the total cost of Minecraft Dungeons.

Step-by-step explanation:

Given that:

Percentage of Minecraft sale = 30% off

Cost of Minecraft Dungeons = x

Amount of discount on Minecraft Dungeons = 30% of x

Amount of discount = \frac{30}{100}*x

Amount of discount = 0.3x

Total cost of Minecraft Dungeons = Total cost - Discount

Total cost of Minecraft Dungeons = x - 0.3x

Hence,

The expression x-0.3x represents the total cost of Minecraft Dungeons.
