Question

Evaluate 0.3y + y/z =10 and z =5

Answer 1

So since z=5 you are going to substitute z in the equation with 5. So it should look like 0.3y+y/5 = 10. So in this problem I assume you are solving for y so you will divide on both sides of the equation. So 0.3y/ 0.3 cancels out and you are left with y/5=10/0.3 so 10/ 0.3 is 33.3333333333. Now you are left with y/5=33.3333333333 . Now didvide 5 on both sides. Y should equal 6.66666666667. This was tricky. Hoped that helped !!!

Answer 2

Answer:

The result is y=20 with z=5

Step-by-step explanation:

The idea is to find the value of y with z=5. To do this, it is necessary to replace the value of z in the left part of the equation and then find the y value.

First step

$0.3y+\frac{y}{z}=10$

$0.3y+\frac{y}{5}=10$

When we replace the z value we obtain the term $\frac{y}{5}$ which equals $\frac{1}{5}y$. Then, $1/5$ equals 0.2.

$0.3y+\frac{1}{5}y=10$

$0.3y+0.2y=10$

Second step

We must add the terms with the y letter. They are 0.3y and 0.2y

$0.5y=10$

Third step

The last step is to pass the 0.5 to divide with 10. It would be:

$y=\frac{10}{0.5}$

$y=20$

The result is y=20 with z=5
