Question

1) 1/7:x=-5/14 2) -5/6•x=-1/73) 2 5/6•x=17/18

Answer 1

вроде так)

1. -0,4

2. 6/35

3. 17/75

Answer 2

To solve the equations, we need to find the value of the variable "x" in each case. Let's solve them one by one:

1. 1/7x = -5/14

To solve for x, we need to isolate it on one side of the equation. To do that, we'll multiply both sides by 7 to get rid of the fraction on the left side:

1/7 * 7 * x = -5/14 * 7

x = -5/2

So, the value of x is -5/2.

2. -5/6 * x = -1/73

Again, let's isolate x by dividing both sides by -5/6:

(-5/6 * x) / (-5/6) = (-1/73) / (-5/6)

x = (-1/73) / (-5/6)

To divide fractions, we multiply the first fraction by the reciprocal of the second fraction:

x = (-1/73) * (-6/5)

x = 6/365

So, the value of x is 6/365.

3. 2 5/6 * x = 17/18

First, convert the mixed number on the left side to an improper fraction:

2 5/6 = (2 * 6 + 5)/6 = 17/6

Now, let's isolate x by dividing both sides by 17/6:

(2 5/6 * x) / (17/6) = (17/18) / (17/6)

x = (17/18) * (6/17)

x = 6/18

Now, simplify the fraction:

x = 1/3

So, the value of x is 1/3.

To summarize:

1. x = -5/2
2. x = 6/365
3. x = 1/3
