Answer 1

Answer:

$\boxed{\mathrm{view \: explanation}}$

Step-by-step explanation:

x(2•x)= 4•5•y

Expand brackets,

2x•x²=20•y

Multiply.

2x³ = 20y

Divide both sides by 2.

x³ = 10y

Take cube root.

x = ∛10y

2x³ = 20y

Divide 20 on both sides.

1/10x³ = y

Answer 2

Answer:

$y = \frac{ {x}^{3} }{10}$

Step-by-step explanation:

$x(2 \times x) = 4 \times 5 \times y \\ 2x \times {x}^{2} = 20y \\ 2 {x}^{3} = 20y \\ \frac{ 2{x}^{3} }{20} = \frac{20y}{20} \\ y = \frac{ {x}^{3} }{10}$
