4x -2(3x+7)
Use the distributive property:
4x - 6x -14
Combine like terms:
-2x - 14
It would make a lot more sense if the choices were 's' instead of '8'. With that being said, the answer should have a value that is greater than -10. That would be a positive number, or a negative number from -1 to -9. <em>So, the acceptable answers would be A and B.</em>

<span>The pressure, P, of a gas, varies inversely with its volume, V
</span>
∴ PV = k where k is constant
<span>The pressure is 84 Pa at a volume of 36 L.
</span>
<span>∴ at P = 84 ⇒⇒⇒ V = 36
</span>
<span>∴ K = PV = 84 * 36 = 3,024 ⇒⇒(1)</span>
If the volume is expanded to 216 L, what will the new pressure be?
We need to find P at V = 216
From the equation (1) ⇒⇒⇒ PV = 3024
substitute with V = 216
∴ 216 P = 3024
∴ P = 3024/216 = 14
The correct answer is option <span>B. 14 Pa</span>
Answer:
15 days
Step-by-step explanation:
Well, since there are 5 cups of oatmeal, and she eats 1/3 a day, then the equation is: 5 divided by 1/3 then change 1/3 to its reciprocal which is 3. 5 times three is 15 so therefore Stella will finish it in 15 days.
