Answer:
2 miles
Step-by-step explanation:
60 min = 1 hour
24 min = x
x = 2/5 hour
1 hour = 5 miles
2/5 hour = y
y = 2 miles
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)

You can multiply the quotient by the divisor to check the answer. Your answer is correct if the product is the dividend. If there is a remainder, add it to the product.
Answer:
x=7.5
Step-by-step explanation:
Let's solve your equation step-by-step.
3(x+4.5)=36
Step 1: Simplify both sides of the equation.
3(x+4.5)=36
(3)(x)+(3)(4.5)=36(Distribute)
3x+13.5=36
Step 2: Subtract 13.5 from both sides.
3x+13.5−13.5=36−13.5
3x=22.5
Step 3: Divide both sides by 3.
3x/3=22.5/3
x=7.5
Answer:
x=7.5
