Question

-4,6+5,9= 7,4+(-3,1)= -7,14+(-1,3)= -2,4-х=-3,16 1/3+х=1/9

Answer 1

-4,6+5,9=1,3
7,4+(-3,1)=7,4-3,1=4,3
-7,14+(-1,3)=-(7,14+1,3)=-8,44
-2,4-х=-3,6
-х=-3,6+2,4
-х=-1,2
х=1,2
1/3+х=1/9
х=1/9-1/3
х=-2/9

Answer 2

Ответ:

Пошаговое объяснение:

-4,6+5,9= 1.3

7,4+(-3,1)= 7.4-3.1=4.3

-7,14+(-1,3)= =-7.14-1.3=-8.44

-2,4-х=-3,16

х=-2.4+3.16

х=0.76

1/3+х=1/9

х=1\9-1\3

х=1\9-3\9

х=-2\9

Answer 3

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

1. -4.6 + 5.9 = 1.3 The result of adding -4.6 and 5.9 is 1.3.

2. 7.4 + (-3.1) = 4.3 The result of adding 7.4 and -3.1 is 4.3.

3. -7.14 + (-1.3) = -8.44 The result of adding -7.14 and -1.3 is -8.44.

4. -2.4 - x = -3.16 To solve for x, we need to isolate x on one side of the equation. First, we'll add 2.4 to both sides: -2.4 - x + 2.4 = -3.16 + 2.4 -x = -0.76 Now, to solve for x, we divide both sides by -1 (the coefficient of x): x = 0.76

5. 1/3 + x = 1/9 To solve for x, we need to isolate x on one side of the equation. First, we'll subtract 1/3 from both sides: 1/3 + x - 1/3 = 1/9 - 1/3 x = 1/9 - 1/3 Now, to find a common denominator, let's convert both fractions to have a denominator of 9: x = 1/9 - 3/9 Now, subtract the fractions: x = -2/9

So, the solutions to the equations are:

1. -4.6 + 5.9 = 1.3
2. 7.4 + (-3.1) = 4.3
3. -7.14 + (-1.3) = -8.44
4. x = 0.76
5. x = -2/9 (or -0.222 recurring)
