Question

--7/8=х/24; -5/1,2=х/6;-1,9/3=х/15​

Answer 1

Ответ:

-7,8=-21/24;

-5/1,2=-25/6;

-1,9/3=-9,5/15.

Answer 2

It looks like you have three different equations that involve solving for the variable "x". Let's solve each equation step by step:

1. Equation 1: -7/8 = x/24

To solve for "x", cross-multiply and then solve for "x":

-7 * 24 = 8 * x -168 = 8x

Divide both sides by 8: x = -168 / 8 x = -21

So, the solution for the first equation is x = -21.

2. Equation 2: -5/1.2 = x/6

First, convert the decimal 1.2 to a fraction: 1.2 = 6/5

Now the equation becomes: -5 / (6/5) = x / 6

Multiply by the reciprocal of 6/5 (which is 5/6) on both sides: -5 * (5/6) = x -25/6 = x

So, the solution for the second equation is x = -25/6.

3. Equation 3: -1.9/3 = x/15

Convert the decimal 1.9 to a fraction: 1.9 = 19/10

Now the equation becomes: -19/10 / 3 = x / 15

Multiply by the reciprocal of 3 (which is 1/3) on both sides: (-19/10) * (1/3) = x / 15 -19/30 = x / 15

Multiply both sides by 15: -19/30 * 15 = x -19/2 = x

So, the solution for the third equation is x = -19/2.

To summarize:

1. x = -21
2. x = -25/6
3. x = -19/2
