Answer:
504
Step-by-step explanation:
Answer:
3x = 50 - 10y
Step-by-step explanation:
Here, x represents the number of 3 lb weights and y represents the number of 10 lb weights,
So, total weight of 3 lb weights = 3x
And, the weight of 10 lb weights = 10y
Total weight of all his weights = 3x + 10y
According to the question,
Total weight = 50 lb,
⇒ 3x + 10y = 50
Or 3x = 50 - 10y
Which is the required equation.
Second option is correct.
The answer is 364 I think .
We are given
edge of cube =x
we know that formula for volume of cube

we are given

we can plug value

now, we can solve for x
![\sqrt[3]{x^3} =\sqrt[3]{\frac{1}{8} cm^3 }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%5E3%7D%20%3D%5Csqrt%5B3%5D%7B%5Cfrac%7B1%7D%7B8%7D%20cm%5E3%20%7D)
