Question

А) Х-5,7 =-2,4 б) -1/12 m =-3; в) m:(-1,6)=0,64

Answer 1

X-5,7=-2,4

x=5,7-2,4

x=3,3

-1\12m=-3

m=-3*(-12\1)

x=36

m:(-1,6)=0,64

m=0,64*(-1,6)

m=-1,024

Answer 2

а) Х-5,7 =-2,4

х=-2,4+5,7

х=3,3

б) -1/12 m =-3;

m=36

в) m:(-1,6)=0,64

m=-1,024

Answer 3

Let's solve each of the equations step by step:

А) X - 5.7 = -2.4

To solve for X, we need to isolate it on one side of the equation. Let's move the constant term to the other side:

X = -2.4 + 5.7

Now, let's add the numbers:

X = 3.3

So the value of X is 3.3.

Б) -1/12 * m = -3

To solve for m, we need to isolate it on one side of the equation. Since m is multiplied by -1/12, we can get rid of the fraction by multiplying both sides of the equation by the reciprocal of -1/12, which is -12:

-12 * (-1/12) * m = -12 * -3

m = 36

So the value of m is 36.

В) m / (-1.6) = 0.64

To solve for m, we'll again isolate it on one side of the equation. In this case, m is divided by -1.6, so we'll get rid of the division by multiplying both sides by -1.6:

m = 0.64 * (-1.6)

Now, let's calculate the value:

m = -1.024

So the value of m is approximately -1.024.
