Simplifying

2x + 3y = 1

Solving

2x + 3y = 1

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3y' to each side of the equation.

2x + 3y + -3y = 1 + -3y

Combine like terms: 3y + -3y = 0

2x + 0 = 1 + -3y

2x = 1 + -3y

Divide each side by '2'.

x = 0.5 + -1.5y

Simplifying

x = 0.5 + -1.5y

Simplify (4x^4y^3)^3/3(5x^2y^6)^2

jolli1 [7]

Answer: Hence, our simplified form will be :

$\frac{64}{75}x^8y^{-3}$

Step-by-step explanation:

Since we have given that

$\frac{(4x^4y^3)^3}{3(5x^2y^6)^2}$

We need to simplify the above expression:

$\frac{(4x^4y^3)^3}{3(5x^2y^6)^2}\\\\=\frac{4^3x^{4\times 3}y^{3\times 3}}{3\times 5^2x^{2\times 2}y^{6\times 2}}\\\\=\frac{64x^{12}y^9}{3\times 25x^4y^{12}}\\\\=\frac{64x^{12}y^9}{75x^4y^{12}}\\\\=\frac{64}{75}x^{12-4}y^{9-12}\\\\=\frac{64}{75}x^8y^{-3}$

Hence, our simplified form will be :

$\frac{64}{75}x^8y^{-3}$

The data below show the wins (W) and losses (L) for a basketball team over 25 consecutive games.

kotykmax [81]

Answer:

0.48 or 48%

Step-by-step explanation:

The relative frequency of wins for the basketball team in question is given by the number of wins over the course of the 25 games, divided by the total number of games.

Observing the given data, 12 'Ws' can be counted, which means that the relative frequency of wins is:

$F_W=\frac{12}{25}\\F_W=0.48$
