Select ALL expressions that are equivalent to -6. * -7 + 13

-10 - (-4)

26 - 32

16 - 10

3 - ( - 3)

Only the 2nd and 3rd expressions are equal to -6

Step-by-step explanation:

The only way to do this is evaluating ot actually doing each expression:

Some key skills needed are subtraction with negative numbers, distributing the negative properly, and addition.

The first one is -7+13. This can be rewritten as 13-7. And this is 6, so it is not equal to -6. The 2nd one is -10-(-4). You have to distribute that minus sign after the -10 to the -4. Think of the subtraction symbol I mentioned as -1. -1(-4) is 4 since the negative signs cancel out. It would then be -10 + 4 which -6. So this works. This one is 26 - 32. You have to subtraction here. 26 - 32 is the opposite of 32 - 26. 32 - 26 is 6, so 26 - 32 would be -6. So the 3rd one is another one eqial to -6. This is simple subtraction. 16 - 10 is 6, so this one definitely does not work. This uses the same skill as number 2. Think of the minus sign after the positive 3 as a -1. -1(-3) is 3, so it would be 3 + 3 which is 6.

Only the 2nd and 3rd ones work. Hope you understood and have a nice day!!

All points to the left of zero on a horizontal number line are negative. a number line is a picture of a graduated straight line that serves as abstraction for real numbers. this number line can be extended to the left to represent numbers which are smaller than 0. such numbers are called negative numbersmark me brainliest
