Question

-3/9-4a=40/200 помогите срочноо пжж​

Answer 1

Ответ:

$- \frac{3}{9} - 4a = \frac{40}{200}$

$- 4a = \frac{1}{5} + \frac{3}{9}$

$- 4a = \frac{9}{45} + \frac{15}{45}$

$- 4a = \frac{24}{45}$

$- 180a = 24$

$a = - \frac{24}{180}$

Answer 2

To solve the equation -3/9 - 4a = 40/200, we can follow these steps:

Step 1: Simplify both sides of the equation. - On the left side, we can simplify -3/9 to -1/3. - On the right side, we can simplify 40/200 to 1/5.

So the equation becomes -1/3 - 4a = 1/5.

Step 2: Get rid of the fractions by multiplying both sides of the equation by the least common denominator (LCD) of 3 and 5, which is 15. - Multiply -1/3 by 15: (-1/3) * 15 = -5. - Multiply 1/5 by 15: (1/5) * 15 = 3.

The equation now becomes -5 - 60a = 3.

Step 3: Solve for 'a'. - To isolate 'a', we need to move the constant term (-5) to the right side of the equation by adding 5 to both sides. - The equation becomes -60a = 3 + 5, which simplifies to -60a = 8.

Step 4: Solve for 'a' by dividing both sides of the equation by -60. - Divide -60a by -60: (-60a) / -60 = a. - Divide 8 by -60: 8 / -60 = -1/15.

So the solution to the equation -3/9 - 4a = 40/200 is a = -1/15.
