False
M+4 1/2 would equal 11 1/2
<span>The canyon starts at an elevation of (-14.5). After each year, the elevation drops by (-1.5). The equation that could be written for this, then, would be (-14.5 - 1.5x = -31). First, we could add 14.5 to both sides of the equation to isolate the unknown. This would leave -1.5x = -16.5. Next, we can remove the negative signs so both sides of the equation are positive and easier to work with. This leaves 1.5x = 16.5. Finally, dividing both sides by 1.5 gives us "x = 11", which means that after 11 years, the canyon floor will be at -31 feet.</span>
Answer:
D.
Step-by-step explanation:
![w = {x}^{2} - 2yz \\ \\ 2yz = {x}^{2} - w \\ \\ \huge \red{ y = \frac{ {x}^{2} - w }{2z} }](https://tex.z-dn.net/?f=w%20%3D%20%20%7Bx%7D%5E%7B2%7D%20%20-%202yz%20%5C%5C%20%20%5C%5C%202yz%20%3D%20%20%7Bx%7D%5E%7B2%7D%20%20-%20w%20%5C%5C%20%20%5C%5C%20%5Chuge%20%5Cred%7B%20y%20%3D%20%20%5Cfrac%7B%20%7Bx%7D%5E%7B2%7D%20-%20w%20%7D%7B2z%7D%20%7D)
Answer:
The given expression 2(8) ÷ (-4) = 4
Step-by-step explanation:
Here, the given expression is : -2(8) ÷ (-4)
Now,we also know that ![a \div b = a \times \frac{1}{b}](https://tex.z-dn.net/?f=%20a%20%5Cdiv%20b%20%3D%20%20a%20%5Ctimes%20%5Cfrac%7B1%7D%7Bb%7D)
So, here ![-2(8) \div (-4) = -2(8) \times \frac{1}{(-4)} = \frac{-16}{-4} = 4](https://tex.z-dn.net/?f=-2%288%29%20%5Cdiv%20%20%28-4%29%20%3D%20%20-2%288%29%20%5Ctimes%20%5Cfrac%7B1%7D%7B%28-4%29%7D%20%20%3D%20%5Cfrac%7B-16%7D%7B-4%7D%20%20%20%3D%204)
⇒ The given expression -2(8) ÷ (-4) = 4
<u>Answer:</u>
<u>Step-by-step explanation:</u>
- 1/2x ÷ 3 = 6
- => 1/2x × 1/3 = 6
- => 6 x 1/6x = 6 x 6
- => x = 36
<u>Conclusion:</u>
Therefore, the answer is 'x = 36'.
Hoped this helped.
