Answer 1

Ответ:

1. -16

2. 8

3. -8

4. x=-15

5. -52

6. -18

7. -72

Пошаговое объяснение:

1. -(45)+(12)+41

1) -45-12+41

2) -45-12=-57

3) -57+41=-16

2. -8+12-(-8)-4

1)-8+12+8-4=8

3. 37-45=-8

4. -18 - х = -3

-18+3=x

x=-15

5. 4*(-8) + 5*(-4)

1) 4*(-8)=-32

2) 5*(-4)=-20

3)-32+(-20)=-32-20=-52

6. -7 + 13 - (-7) + (-27) -4

1)-7+13+7-27-4=-18

7. -12*6=-72

Answer 2

Let's solve each of these mathematical expressions:

1. (-45) + (-12) + 41 = -45 - 12 + 41 = -56 + 41 = -15

2. -8 + 12 - (-8) - 4 = -8 + 12 + 8 - 4 = 8

3. 37 - 45 = -8

4. -18 - x = -3 To solve for x, you can add 18 to both sides of the equation: -18 - x + 18 = -3 + 18 -x = 15 Now, divide both sides by -1 to isolate x: x = -15

5. 4 * (-8) + 5 * (-4) = -32 - 20 = -52

6. -7 + 13 - (-7) + (-27) - 4 = -7 + 13 + 7 - 27 - 4 = -18 - 27 - 4 = -45 - 4 = -49

7. -12 * 6 = -72
