Question

(30+0.3х)/ (600+х ) = 0.15.

Answer 1

Ответ:

Пошаговое объяснение:

(30+0,3x)/(600+x)=0,15

30+0,3x=0,15*(600+x)

30+0,3x=90+0,15x

0,3x-0,15x=90-30

0,15x=60

x=60/0,15

x=400

Answer 2

To solve the equation (30 + 0.3x) / (600 + x) = 0.15, we need to find the value of x that satisfies the equation.

Step 1: Eliminate the fraction by multiplying both sides of the equation by (600 + x):

(600 + x) * (30 + 0.3x) / (600 + x) = 0.15 * (600 + x)

Step 2: Simplify the equation:

30 + 0.3x = 0.15 * (600 + x)

Step 3: Distribute the right side of the equation:

30 + 0.3x = 90 + 0.15x

Step 4: Move all the terms with x to one side of the equation and the constants to the other side:

0.3x - 0.15x = 90 - 30

Step 5: Combine like terms:

0.15x = 60

Step 6: Solve for x by dividing both sides of the equation by 0.15:

x = 60 / 0.15

Step 7: Calculate the value of x:

x = 400

So, the value of x that satisfies the equation is x = 400.
