Question

48x√7 = 1/2 (x+8) X 11.2
​

Answer 1

Step-by-step explanation:

$48 \sqrt{7} = \frac{1}{2} (x + 8) \times 11.2 \\ \frac{48 \sqrt{7} \times 2}{11.2} = x + 8 \\ \frac{48 \sqrt{7} }{5.6} = x + 8 \\ \frac{480 \sqrt{7} }{56} - 8 = x \\ \frac{60 \sqrt{7} }{7} - 8 = x \\ \frac{158.4}{{7} } - 8 = x \\ \frac{158.4 - 56}{7} = x \\ \frac{102.4}{7} = x \\ x = 14.63$

x = 14.63 (approx)

Answer 2

Answer:

48√7 = 1 (x+8) 11.2

2

{divide 11.2 by 1

2 }

48√7 = (x+8) 5.6

{multiply x+8 by 5.6}

48√7 = 5.6x + 44.8

48√7 – 44.8 = 5.6x
