Math question: If 2x + 5y - 3z = 7750, and x = 500, y = 1000, and z = 100, what is the value of 4x - 2y + z?

Plugging in the given values, we have 2(500) + 5(1000) - 3(100) = 7750. Thus, the equation holds true. Now, substituting x = 500, y = 1000, and z = 100 into the expression 4x - 2y + z, we get 4(500) - 2(1000) + 100 = 2000 - 2000 + 100 = 100. Therefore, the value of 4x - 2y + z is 100.

Math question: What is the sum of 7750, its square root rounded to the nearest whole number, and its cube root rounded to the nearest whole number?
