Question

X × y=6 и y ×z=8 найдите (x×z)/(x-z)​

Answer 1

Решение задания приложено. В таких заданиях просится, чтобы в ответе не было переменной. Красным, я предположила, что в числителе х+z. Если нет, то значит

- 24/y

Answer 2

Пошаговое объяснение:

xy=6; yz=8

x=6/y; z=8/y

xz/(x-z)=(6/y •8/y)/(6/y -8/y)=(48/y^2)/(-2/y)=-24/y

Answer 3

To find the value of (x × z) / (x - z), we need to solve the given equations first:

1. x × y = 6
2. y × z = 8

Let's solve these equations step by step:

From equation 1, we can isolate x by dividing both sides of the equation by y:

x = 6 / y

Now substitute this value of x into equation 2:

(6 / y) × z = 8

Multiply both sides of the equation by y to eliminate the fraction:

6z = 8y

Now, let's solve for y in terms of z:

y = (6z) / 8

Simplifying further:

y = (3z) / 4

Now, substitute the value of y back into the equation x = 6 / y:

x = 6 / [(3z) / 4] x = (6 × 4) / (3z) x = 24 / (3z) x = 8 / z

Finally, substitute the values of x and y into the expression (x × z) / (x - z):

[(8 / z) × z] / [(8 / z) - z] = 8 / (1 - z^2 / z) = 8 / (1 - z) = 8 / (1 - z)

So, the value of (x × z) / (x - z) is 8 / (1 - z).
