Question

3/80•x + 5/8•x-3,6=8,4

Answer 1

Ответ:

3/80x + 5/8x= 8,4 + 3,6

3/80x + 5/8x= 10

1) 3/80x + 5/8x = 3/80x + 5/8x •10= 3/80x + 50/80x= 53/80x

2) 53/80x = 10

x= 53/80 : 10 = 53/8 = 6 5/8

Answer 2

It looks like you have an equation involving fractions and a variable $x$. Let's solve it step by step.

The equation you provided is:

$\frac{3}{80} \cdot x + \frac{5}{8} \cdot x - 3.6 = 8.4$

To solve for $x$, we'll follow these steps:

Step 1: Combine the fractions on the left side of the equation: $\frac{3}{80} \cdot x + \frac{5}{8} \cdot x = \frac{3 \cdot x}{80} + \frac{5 \cdot x}{8} = \frac{3x}{80} + \frac{10x}{80} = \frac{13x}{80}$

Step 2: Substitute the combined fraction back into the equation: $\frac{13x}{80} - 3.6 = 8.4$

Step 3: Add 3.6 to both sides of the equation to isolate the fraction: $\frac{13x}{80} = 12$

Step 4: Multiply both sides by 80 to solve for $x$: $13x = 12 \cdot 80$

$13x = 960$

Step 5: Divide both sides by 13 to find the value of $x$: $x = \frac{960}{13}$

This is the simplified solution for $x$, and you can calculate the approximate decimal value for $x$ if needed.
