On the checkerboard, 4/10 of the pieces left are red. What fraction of the pieces left are black? Write the equation.

Alexeev081 [22]

Answer:

The fraction of black pieces left is $\frac{6}{10}$

Step-by-step explanation:

Given as :

On the checkerboard , The fraction of red pieces left = $\frac{4}{10}$

Let The fraction of black pieces left = x

So, The fraction of black pieces left = x = 1 - $\frac{4}{10}$

Or, x = $\frac{10-4}{10}$

Or, x = $\frac{6}{10}$

Hence The fraction of black pieces left is $\frac{6}{10}$ Answer

Solve (9x-4)^2=18 using the square root method

Damm [24]

Answer:

x = 4/9 + sqrt(2)/3 or x = 4/9 - sqrt(2)/3

Step-by-step explanation:

Solve for x over the real numbers:

(9 x - 4)^2 = 18

Take the square root of both sides:

9 x - 4 = 3 sqrt(2) or 9 x - 4 = -3 sqrt(2)

Add 4 to both sides:

9 x = 4 + 3 sqrt(2) or 9 x - 4 = -3 sqrt(2)

Divide both sides by 9:

x = 4/9 + sqrt(2)/3 or 9 x - 4 = -3 sqrt(2)

Add 4 to both sides:

x = 4/9 + sqrt(2)/3 or 9 x = 4 - 3 sqrt(2)

Divide both sides by 9:

Answer: x = 4/9 + sqrt(2)/3 or x = 4/9 - sqrt(2)/3
