(2x+8)/6=1/3(x+4)
3(2x+8)=6(x+4)
6x+24=6x+24.
0=0.
∴There are no real solutions.
By factoring the quadratic equation, 4 porcelain vases can be glazed with 20 pints of glaze. (Correct choice: B)
<h3>How much vases can be glazed with a certain amount of pints of glass?</h3>
Herein we have a quadratic equation that models the quantity of pints as a function of the number of vases, we need to solve the quadratic equation for v to find the required quantity. The complete procedure is shown below:
v² + v = 20 Given
v² + v - 20 = 0 Compatibility with addition / Existence of the additive inverse / Modulative property
(v + 5) · (v - 4) = 0 x² - (r₁ + r₂) · x + r₁ · r₂ = (x - r₁) · (x - r₂)
The result must be a positive number and, thus, the maximum number of vases must be equal to 4. By factoring the quadratic equation, 4 porcelain vases can be glazed with 20 pints of glaze. (Correct choice: B)
