Question

(250:y-50)*80=600 решите ​

Answer 1

250:у-50=600:80

250:у=7,5+50

250:у=57,5

У=250:57,5

У=4 8\23

Answer 2

$(250 \div y - 50) \times 80 = 600$

$250 \div y - 50 = 600 \div 80$

$250 \div y - 50 = 7.5$

$250 \div y = 7.5 + 50$

$250 \div y = 57.5$

$y = 250 \div 57.5$

$y = \frac{100}{23}$

$y = 4 \frac{8}{23}$

Answer 3

To solve the equation (250:y-50)*80 = 600, follow these steps:

Step 1: Remove the parentheses. Step 2: Simplify the expression. Step 3: Solve for 'y'.

Let's go through each step:

Step 1: Remove the parentheses. (250:y-50)*80 = 600 Now, we can rewrite it as: (250 / (y - 50)) * 80 = 600

Step 2: Simplify the expression. To simplify further, let's get rid of the fraction. We can do this by multiplying both sides of the equation by (y - 50)/80: (250 / (y - 50)) * 80 * (y - 50)/80 = 600 * (y - 50)/80

This will cancel out the (y - 50)/80 term on the left side: 250 * (y - 50)/80 = 600 * (y - 50)/80

Now, we have: 250 * (y - 50) = 600 * (y - 50)

Step 3: Solve for 'y'. Next, distribute the multiplication on both sides: 250y - 25050 = 600y - 60050

Now, let's gather the 'y' terms on one side and the constant terms on the other side of the equation: 250y - 12500 = 600y - 30000

Subtract 250y from both sides: -12500 = 600y - 250y - 30000

Simplify further: -12500 = 350y - 30000

Now, add 30000 to both sides: 350y = 30000 - 12500 350y = 17500

Finally, solve for 'y' by dividing both sides by 350: y = 17500 / 350 y = 50

The solution to the equation is y = 50.
