Answer:

30 feet

Step-by-step explanation:

Interesting question.

1 cubit = 18 inches
20 cubits = x
1/20 = 18/x Cross multiply
x = 20 * 18
x = 360 inches.

The maximum height is 360 inches.

1 foot = 12 inches
x feet = 360 inches Cross multiply
12x = 360 * 1
12x/12 = 360/12
x = 30

The maximum height reached was 30 feet.

Veronica tried to solve an equation step by step.

Svetach [21]

No steps are wrong. To solve this equation, you need to isolate the y. So, you would add 4.6 to both sides to cancel out the 4.6 on the right side and isolate the y.

Solve for the value of x: x/2 + x/3 = 2x/5 + 3 , also I need a very thorough explanation for this.

Alona [7]

Answer:

$x=\frac{90}{13} .$

Step-by-step explanation:

$\frac{x}{2} +\frac{x}{3} =\frac{2x}{5} +3;$

$30*(\frac{x}{2} +\frac{x}{3} )=30*(\frac{2x}{5} +3);$

15x+10x=12x+90; ⇔ 13x=90;

$x=\frac{90}{13}.$
