Question

4x+0,2(1-x)=0,35 Решить, ответ должен быть 0,75

Answer 1

4x+0,2(1-x)=0,35
4x+0,2-0,2x=0,35
3,8x=0,15
x=15/380
x=3/76 Ответ:{3/76}

Answer 2

$\bf 4x + 0,2(1 - x) = 0,35$
$\bf 4x + 0,2 - 0,2x = 0,35$
$\bf 3,8x + 0,2 = 0,35$
$\bf 3,8x = 0,35 - 0,2$
$\bf 3,8x = 0,15$
$\bf x = \dfrac{3}{76}}$

Answer 3

To solve the equation 4x + 0.2(1 - x) = 0.35, follow these steps:

Step 1: Distribute the 0.2 through the parentheses: 4x + 0.2 - 0.2x = 0.35

Step 2: Combine like terms: 4x - 0.2x + 0.2 = 0.35

Step 3: Combine constants on the right side: 3.8x + 0.2 = 0.35

Step 4: Isolate the variable term on one side (subtract 0.2 from both sides): 3.8x = 0.35 - 0.2

Step 5: Simplify the right side: 3.8x = 0.15

Step 6: Solve for x (divide both sides by 3.8): x = 0.15 / 3.8

Step 7: Calculate the value of x: x ≈ 0.03947368421052631578947

The solution for x is approximately 0.0395, not 0.75 as mentioned in the answer. There might be an error in the calculation or the equation provided. Please recheck the equation or clarify if there's any mistake.
