Answer 1

Ответ:

Пошаговое объяснение:

1)-4*(-5)-(-30):6 = 20 + 30:6 = 20 + 5 = 25

2)(-8+32):(-6)-7 = 24 : (-6) - 7 = -4 - 7 = -11

3)-6*4-64:(-33+17) = -24 - 64 : (-16) = -24 + 4 = -20

4)1 5/12:(-5/6+2/3) = 1 5/12 : (-5/6 + 4/6) = 1 5/12 : (-1/6) = 17/12 *(-6) = -17/2 = -8 1/2

Answer 2

1. Let's solve the expression step by step:

-4 * (-5) = 20 -(-30) = 30 20 + 30 = 50 50 ÷ 6 = 8.33 (rounded to two decimal places)

So, the solution to the expression -4*(-5)-(-30):6 is approximately 8.33.

2. Let's solve the expression step by step:

-8 + 32 = 24 -6 ÷ -6 = 1 1 - 7 = -6

So, the solution to the expression (-8+32):(-6)-7 is -6.

3. Let's solve the expression step by step:

-6 * 4 = -24 -33 + 17 = -16 -64 ÷ -16 = 4

So, the solution to the expression -6*4-64:(-33+17) is 4.

4. Let's solve the expression step by step:

1 5/12 = 17/12 -5/6 + 2/3 = -5/6 + 8/12 = -5/6 + 4/6 = -1/6

17/12 ÷ -1/6 = (17/12) * (-6/1) = -17/2

So, the solution to the expression 1 5/12:(-5/6+2/3) is -17/2 or -8.5.
