Question

8•(-3)+(-7); (-2)•(-5)-12; 35-(-7)•6

Answer 1

1) 8*(-3)+(-7)=-24-7=-31
2) (-2)*(-5)-12=10-12=-2
3) 35-(-7)*6=35-(-42)=35+42=77

Answer 2

Let's solve each expression step by step:

1. 8•(-3) + (-7) First, multiply 8 by -3: 8 • (-3) = -24

   Now, add -7 to the result: -24 + (-7) = -31

   Therefore, the value of the expression is -31.

2. (-2)•(-5) - 12 First, multiply -2 by -5: (-2) • (-5) = 10

   Now, subtract 12 from the result: 10 - 12 = -2

   Therefore, the value of the expression is -2.

3. 35 - (-7)•6 First, multiply -7 by 6: (-7) • 6 = -42

   Now, subtract -42 from 35: 35 - (-42) = 35 + 42 = 77

   Therefore, the value of the expression is 77.

So, the values of the given expressions are:

1. 8•(-3) + (-7) = -31
2. (-2)•(-5) - 12 = -2
3. 35 - (-7)•6 = 77
