Question

-(+46)=? -(-10)=? -(-89,1)=? -(+32)+? -(-?)=-7,5

Answer 1

-46
+10
+89,1
-32
+7,5 я так думаю

Answer 2

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

1. -(+46) = ? When you have a positive number inside parentheses preceded by a negative sign, it becomes negative. -(+46) = -46

2. -(-10) = ? When you have a negative number inside parentheses preceded by a negative sign, it becomes positive. -(-10) = 10

3. -(-89.1) = ? When you have a negative number inside parentheses preceded by a negative sign, it becomes positive. -(-89.1) = 89.1

4. -(+32) + ? = -7.5 To find the missing value represented by the question mark, we'll solve for it. Let's denote the missing value as "x." -(+32) + x = -7.5

To isolate "x," we can move the positive 32 to the other side by adding it to both sides of the equation: x = -7.5 + 32 x = 24.5

5. -(-?) = -7.5 Let's find the value represented by the question mark. To do this, we know that when you have a negative number inside parentheses preceded by a negative sign, it becomes positive. So we have: -(-x) = -7.5

To isolate "x," we can move the negative sign to the other side by changing its sign: x = 7.5

So, the final values are: -46 10 89.1 24.5 7.5
