Verified answer

Explicación paso a paso:

20)

[tex] \frac{y}{3} = \frac{ \frac{64}{3} }{y} [/tex]

[tex] {y}^{2} = 3 \times \frac{64}{3} [/tex]

[tex] {y}^{2} = 64[/tex]

[tex]y = \sqrt{64} [/tex]

[tex]y = 8[/tex]

21)

-20 1/4

= ( 4×-20 + 1)/4

= -81/4

[tex] \frac{ - \frac{81}{4} }{z} = \frac{z}{ - 4} [/tex]

[tex] - 4 \times - \frac{81}{4} = {z}^{2} [/tex]

[tex]81 = {z}^{2} [/tex]

[tex] \sqrt{81} = z[/tex]

[tex]9 = z[/tex]

22)

[tex] \frac{w}{5} = \frac{125}{w} [/tex]

[tex] {w}^{2} = 5 \times 125[/tex]

[tex] {w}^{2} = 625[/tex]

[tex]w = \sqrt{625} [/tex]

[tex]w = 25[/tex]
