Question

( x - 1/4 ) : 2. 8 = -4

Answer 1

1/4=0.25
2.8*-4=-11.2
-11.2+0.25=-10.95
ответ: -10.95

Answer 2

To solve the equation $(x - \frac{1}{4}) : 2.8 = -4$, you can follow these steps:

Step 1: Eliminate the fraction by multiplying both sides by 2.8 Step 2: Solve for $x$

Let's proceed with the solution:

Step 1: $(x - \frac{1}{4}) \times \frac{1}{2.8} = -4 \times \frac{1}{2.8}$

Step 2: $x - \frac{1}{4} = -\frac{4}{2.8}$

Now, simplify the right side of the equation:

$x - \frac{1}{4} = -\frac{4}{2.8} = -\frac{20}{14} = -\frac{10}{7}$

Step 3: Isolate $x$ by adding $\frac{1}{4}$ to both sides:

$x = -\frac{10}{7} + \frac{1}{4}$

Step 4: To combine the fractions on the right side, find a common denominator, which is 28:

$x = -\frac{40}{28} + \frac{7}{28}$

Step 5: Now, combine the fractions:

$x = \frac{-40 + 7}{28} = \frac{-33}{28}$

So, the solution to the equation is $x = -\frac{33}{28}$.
