Question

1)-9.(-3) - (-35): 7;2) 17:(-17)-(-32):4;3) - 33+(-5.7+7):(-2).4) (-28+52):(8) -6​

Answer 1

• -9*(-3)-(-35):7= -27-(-7) = -20
• 17:(-17)-(-32):4= 0-(-8) = -8
• -33+(-5*7+7):(-2)= -33+(-28) = -61
• (-28+52):(8)-6 = 24:8-6 = 3-6 = -3

Answer 2

Let's solve each of these expressions step by step:

1. -9(-3) - (-35):7 First, calculate -9(-3): -9(-3) = 27

   Now, simplify the expression: 27 - (-35):7

   Next, calculate -(-35): -(-35) = 35

   Now, the expression becomes: 27 - 35:7

   Finally, calculate 35 divided by 7: 35:7 = 5

   So, the final answer is: 27 - 5 = 22

2. 17:(-17) - (-32):4 First, calculate 17:(-17): 17:(-17) = -1

   Now, simplify the expression: -1 - (-32):4

   Next, calculate -(-32): -(-32) = 32

   Now, the expression becomes: -1 - 32:4

   Finally, calculate 32 divided by 4: 32:4 = 8

   So, the final answer is: -1 - 8 = -9

3. -33 + (-5.7 + 7):(-2) First, calculate -5.7 + 7: -5.7 + 7 = 1.3

   Now, simplify the expression: -33 + 1.3:(-2)

   Finally, calculate 1.3 divided by -2: 1.3:(-2) = -0.65

   So, the final answer is: -33 - 0.65 = -33.65

4. (-28 + 52):8 - 6 First, calculate -28 + 52: -28 + 52 = 24

   Now, simplify the expression: 24:8 - 6

   Finally, calculate 24 divided by 8: 24:8 = 3

   So, the final answer is: 3 - 6 = -3

The solutions to the expressions are as follows:

1. 22
2. -9
3. -33.65
4. -3
