Answer 2

1).

$3 \sqrt{x} - 5 = 0.22$

$3 \sqrt{x} = 0.22 + 5$

$3 \sqrt{x} = 5.22$

$\sqrt{x} = \frac{5.22}{3}$

$\sqrt{x} = 1.74$

$( \sqrt{x})^{2} = {1.74}^{2}$

$x = 3.0276$

$x = 3.02$

2).

$- 4 + 6 \sqrt{x} = 6.5$

$6 \sqrt{x} = 6.5 + 4$

$6 \sqrt{x} = 10.5$

$\sqrt{x} = \frac{10.5}{6}$

$\sqrt{x} = 1.75$

$( \sqrt{x})^{2} = {1.75}^{2}$

$x = 3.0625$

$x = 3.06$

3).

$- 11 \sqrt{x} + 7.2 = - 12.71$

$- 11 \sqrt{x} = - 12.71 - 7.2$

$- 11 \sqrt{x} = - 19.91$

$\sqrt{x} = \frac{ - 19.91}{ - 11}$

$\sqrt{x} = 1.81$

$( \sqrt{x})^{2} = {1.81}^{2}$

$x = 3.2761$

$x = 3.27$
