Can someone please help me solve this?
[5(1-2)-5]-[3-(3-7]
Please show me your work, I will critique it for you.
I think I came up with the right answer.
-17
yes.
Of course! Let's break down the equation step by step to solve it.
First, let's simplify the expression inside the square brackets: [5(1-2)-5].
The part inside the parentheses, (1-2), simplifies to -1.
So the expression becomes: 5(-1)-5.
Multiply 5 by -1, which gives you -5. Then subtract 5 from -5.
-5 - 5 equals -10.
Next, let's simplify the expression inside the other set of square brackets: [3-(3-7)].
The part inside the parentheses, (3-7), simplifies to -4.
So the expression becomes: 3-(-4).
When you subtract a negative number, it is the same as adding its positive counterpart. So, 3 - (-4) is the same as 3 + 4, which equals 7.
Now that we have simplified both sets of square brackets, we can simplify the overall expression: -10 - 7.
Simply subtract 7 from -10.
-10 - 7 equals -17.
Therefore, the solution to the expression [5(1-2)-5]-[3-(3-7)] is -17.
