Question

(7 200 : 80) : x = 30​

Answer 1

Ответ:

$x = 3$

Пошаговое объяснение:

$(7200 \div 80) \div x = 30 \\ 90 \div x = 30 \\ \frac{90}{x} = 30 \\ 90 = 30x \\ 30x = 9 0\\ x = 90 \div 30 \\ x = 3$

90:x=30

x=90:30

x=3

Answer 3

To solve the equation (7,200 : 80) : x = 30, let's break it down step by step.

First, let's simplify the expression (7,200 : 80). The symbol ":" represents division, so we divide 7,200 by 80:

(7,200 : 80) = 90

Now, the equation becomes 90 : x = 30.

To find the value of x, we need to isolate it on one side of the equation. We can achieve this by multiplying both sides of the equation by x:

x * (90 : x) = x * 30

On the left side, the x in the numerator and denominator cancels out:

90 = 30x

Next, we divide both sides of the equation by 30 to solve for x:

90 / 30 = (30x) / 30

3 = x

Therefore, the solution to the equation (7,200 : 80) : x = 30 is x = 3.
