(2x² - 40x² – 28) /(x² – 5x – 2)

Mathematics
1 answer:
erastova [34]4 years ago
4 0

Answer:

x = i sqrt(14/19) or x = -i sqrt(14/19)

Step-by-step explanation:

Solve for x:

(-38 x^2 - 28)/(x^2 - 5 x - 2) = 0

Multiply both sides by x^2 - 5 x - 2:

-38 x^2 - 28 = 0

Add 28 to both sides:

-38 x^2 = 28

Divide both sides by -38:

x^2 = -14/19

Take the square root of both sides:

Answer: x = i sqrt(14/19) or x = -i sqrt(14/19)

wolverine [178]

Answer:

x =  \frac{5}{12}

Step-by-step explanation:

\frac{3}{2x}  -  \frac{2}{3x}

➡️ \frac{3}{2x}  -  \frac{2}{3x}  = 2

➡️ \frac{5}{6x}  = 2

Percy paid $24.10 for a basketball. The price of the basketball was $22.99. What was the sales tax rate?
Bess [88]
First, determine the difference between the amount Percy paid and the price of the basketball. That is, $24.10 - $22.99 = $1.11. Divide this value by the price of the basketball and multiply the quotient by 100% to get the tax rate. 
                            ($1.11 / $22.99) x 100% = 4.8%
Thus, the sales tax is approximately equal to 4.8%.
