Respuesta :

3/7 = 15/z

using cross products

3z = 7*15

3z = 105

divide by 3

z = 35

Answer:

yes Z= 35

Step-by-step explanation:

3  = 15

7   =  z

Cross multiply:

3 * z = 7 * 15

Simplifying

3 * z = 7 * 15

Multiply 7 * 15

3z = 105

Solving

3z = 105

Solving for variable 'z'.

Move all terms containing z to the left, all other terms to the right.

Divide each side by '3'.

z = 35

Simplifying

z = 35
