Question

19z-16,5z=18,9275 Please

Answer 1

Ответ:

$7,571.$

Пошаговое объяснение:

$19z-16,5z=18,9275\\2,5z=18,9275\\z=\frac{189275}{25000}=\frac{37855}{5000}=\frac{7571}{1000}=7,571$

Answer 2

To solve the equation for z, you'll need to isolate the variable z on one side of the equation. Here's how you can do it step by step:

Given equation: 19z - 16.5z = 18.9275

Step 1: Combine the like terms on the left side of the equation: (19z - 16.5z) = 2.5z

Step 2: Substitute the value back into the equation: 2.5z = 18.9275

Step 3: Solve for z by dividing both sides of the equation by 2.5: z = 18.9275 / 2.5 z = 7.570

So, the solution for the equation is z = 7.570.
