Answer:
Step-by-step explanation:
5x + 3 > 48
5x > 48 - 3
5x > 45
x > 45/ 5
x > 9
<span> The geometric mean of two non negative numbers x and y is √(xy). (mean square root of XY)
So the geometric mean of 2/3 and 27/40 is
√(2/3 * 27/40)
= √(54 / 120)
= √(27 / 60)
= √(9 / 20)
= 3 / √20
= 3 / 2√5
= 3√5 / 10. </span>
