Question

1)56:(-7)+3= 2)-8х(-5)+75:(-15)= 3-(12-28):(-4)х5= 4)19-(2-18:3)= 5)-60:15+7х(6-14)= 6)-11х(5-9)-60:(-12)=

Answer 1

1)-8+3=-5
2)40+-5=35
3)-40:(-20)=2
4)19+4=23
5)-4-56=60
6)44-(-5)=49

Answer 2

1) 56 : ( -7 ) + 3 = -8 + 3 = -5;

2) -8х ( -5 ) + 75 : ( -15 ) = 40 + ( -5 ) = 35;

3) 3 - ( 12 - 28 ) : ( -4 ) х5 = -40 : ( -20 ) = 2;

4) 19 - ( 2 - 18 : 3 ) = 19 + 4 = 23;

5) - 60 : 15 + 7х ( 6 - 14 ) = -4 - 56 = 60;

6) - 11х ( 5 - 9 ) - 60 : ( -12 ) = 44 - ( -5 ) = 49.

Answer 3

Let's solve the given equations one by one:

1. 56:(-7) + 3

First, let's simplify the division operation: 56 ÷ (-7) = -8

Now, we can substitute this result back into the equation: -8 + 3 = -5

Therefore, the solution to this equation is -5.

2. -8 × (-5) + 75:(-15)

First, let's simplify the multiplication operation: -8 × (-5) = 40

Now, let's simplify the division operation: 75 ÷ (-15) = -5

Finally, we can substitute these results back into the equation: 40 + (-5) = 35

Therefore, the solution to this equation is 35.

3. 3 - (12 - 28):(-4) × 5

First, let's simplify the subtraction inside the parentheses: 12 - 28 = -16

Now, let's simplify the division operation: -16 ÷ (-4) = 4

Finally, let's perform the multiplication operation and subtract it from 3: 3 - (4 × 5) = 3 - 20 = -17

Therefore, the solution to this equation is -17.

4. 19 - (2 - 18:3)

First, let's simplify the division operation: 18 ÷ 3 = 6

Now, let's simplify the subtraction inside the parentheses: 2 - 6 = -4

Finally, let's subtract -4 from 19: 19 - (-4) = 19 + 4 = 23

Therefore, the solution to this equation is 23.

5. -60 ÷ 15 + 7 × (6 - 14)

First, let's simplify the division operation: -60 ÷ 15 = -4

Now, let's simplify the subtraction inside the parentheses: 6 - 14 = -8

Finally, let's perform the multiplication operation and add it to -4: -4 + (7 × (-8)) = -4 + (-56) = -60

Therefore, the solution to this equation is -60.

6. -11 × (5 - 9) - 60 ÷ (-12)

First, let's simplify the subtraction inside the parentheses: 5 - 9 = -4

Now, let's simplify the division operation: -60 ÷ (-12) = 5

Finally, let's perform the multiplication operation and subtract it from -4: -11 × (-4) - 5 = 44 - 5 = 39

Therefore, the solution to this equation is 39.

To summarize:

1. 56:(-7) + 3 = -5
2. -8 × (-5) + 75:(-15) = 35
3. 3 - (12 - 28):(-4) × 5 = -17
4. 19 - (2 - 18:3) = 23
5. -60 ÷ 15 + 7 × (6 - 14) = -60
6. -11 × (5 - 9) - 60 ÷ (-12) = 39
