Answer 2

Let's solve the given expressions step by step:

Expression 1: (-8 + 10 – 7) : (-5) First, let's simplify the numerator: (-8 + 10 – 7) = -5 Now, divide the numerator by the denominator: -5 / (-5) = 1

Therefore, the value of the expression (-8 + 10 – 7) : (-5) is 1.

Expression 2: (-49) - 8 : (-7) * 4 First, let's simplify the division: (-49) - 8 : (-7) = (-49) - (-1) = -48 Now, multiply the result by 4: -48 * 4 = -192

Therefore, the value of the expression (-49) - 8 : (-7) * 4 is -192.

Expression 3: (-90 - 40 - 20) : 15 First, let's simplify the numerator: (-90 - 40 - 20) = -150 Now, divide the numerator by the denominator: -150 / 15 = -10

Therefore, the value of the expression (-90 - 40 - 20) : 15 is -10.
