Joan is selling handmade bead necklaces

Lana71 [14]

Answer:. x = 18

Step-by-step explanation:

Solve by substitution. Given: y= 12x. Rewrite the original equation y= 180 + 2x to 12x = 180 +2x. Subtract 2x from both sides. 10x = 180. Then divide both sides by 10.

x=18

So once she has sold 18 necklaces, she has covered her costs (180 + 36) and she begins to make a profit.

The equation T squared = A cubed shows the relationship between a planet's orbital period, T, and the planet's mean distance fro

Dafna11 [192]

Answer:

Ty = √k * Tx

The orbital period of Y has to be be multiplied by √k . or . k∧1/2

Step-by-step explanation:

The general equation:

T² = A³

is for the case of planet X

Tₓ² = Aₓ³

In the case of planet Y

Ty² = k * Aₓ³ . and Aₓ³ = Tₓ²

By substitution:

Ty² = k *Tₓ²

Ty = √k * Tx

Answer:

$26 \frac{3}{4}$

Step-by-step explanation:

a = 3
$b = \frac{1}{2}$

<h3>Answer</h3>

${a}^{3} - {b}^{2}$
