Question

Найдите значкние выражкния : - с , если с = 40; - 2, 2 ; 9/16; - 220; 4 1/7

Answer 1

с= 40 -с=-40

с= -2 -с=2

с=2  -с=-2

с= 9\16 -с=-9\16

с= -220 -с=220

с= 4 1\7 -с= -4 1\7

Answer 2

To find the value of the expressions, we simply substitute the given values of "c" and the other numbers into the expressions. Let's calculate each expression:

1. Expression: -s, if s = 40 Result: -s = -(40) = -40

2. Expression: -2 Result: -2

3. Expression: 2 Result: 2

4. Expression: 9/16 Result: 9/16

5. Expression: -220 Result: -220

6. Expression: 4 1/7 (or 4 + 1/7) To convert the mixed number to an improper fraction: 4 1/7 = (4 * 7 + 1) / 7 = 29/7 Result: 4 1/7 = 29/7

So the values of the expressions are:

1. -s (if s = 40) = -40
2. -2
3. 2
4. 9/16
5. -220
6. 4 1/7 = 29/7
