Question

-х:(-3/4)=-2 1/4 и - 0,01*(-х)=-0,009

Answer 1

-х:(-3/4)=-2 1/4
-х= -2 1/4*(-3/4)
-х=-9/4*(-3/4)
-х= 27/8
х= -3 3/8

- 0,01*(-х)=-0,009
-х= -0,009:(-0,01)
-х=0,9
х= -0,9

Answer 2

Let's solve the given equations step by step:

1. Equation 1: -x * (-3/4) = -2 1/4

To solve this equation, we need to isolate x on one side of the equation. First, let's convert -2 1/4 into a fraction.

-2 1/4 = -2 - 1/4 = -9/4

Now, the equation becomes:

-x * (-3/4) = -9/4

To isolate x, divide both sides by (-3/4):

x = (-9/4) / (-3/4)

x = (-9/4) * (-4/3)

x = 9/3

x = 3

So, the solution for the first equation is x = 3.

2. Equation 2: -0.01 * (-x) = -0.009

To solve this equation, divide both sides by -0.01:

(-x) = -0.009 / (-0.01)

(-x) = 0.9

Now, multiply both sides by -1 to isolate x:

x = -0.9

So, the solution for the second equation is x = -0.9.

To summarize:

1. x = 3
2. x = -0.9
