Question

Как из этого соотношения с x-ми получить ED, которое будет равно 0.8: 2x/5x=ED/2. С x-ами у меня не получается такой ответ. Подскажите, пожалуйста.

Answer 1

Пошаговое объяснение:

2х/5х=ЕD/2

ED=2x×2/5x=4x/5x=4/5=0,8

Answer 2

Solving the Equation

To solve the equation 2x/5x = ED/2 and find the value of ED that is equal to 0.8, we can use cross-multiplication.

Cross-multiplication involves multiplying the numerator of one fraction by the denominator of the other fraction and vice versa. In this case, we can cross-multiply as follows:

(2x)(2) = (5x)(ED)

Simplifying the equation, we have:

4x = 10x(ED)

Next, we can divide both sides of the equation by 10x to isolate ED:

4x / (10x) = ED

Simplifying further, we get:

0.4 = ED

Therefore, the value of ED that satisfies the equation 2x/5x = ED/2 and is equal to 0.8 is ED = 0.4.
