Answer 1

-24

Answer 2

Your answer is correct. I'm seeing a lot of -24s as answers, but I don't understand why. Two negatives make a positve. If I subtract a negative, it's the same as adding a positive. If I add a negative, it's the same as subtracting a number.

Set it up as:

14+(-17)-(-34)+x-(-21)=40

Simplify the forms:

14-17+34+x+21=40.

Now, do the math. 14-17=(-3). -3+34=31. 31+21=52. To find x, we subtract 52 from each side, to get x= (-12).

Check:

14+(-17)-(-34)+(-12)-(-21)=X

14-17=-3.

-3+34= 31.

31-12=19

19+21=40

Your answer is correct.

Answer 3

14-17+34-12+21 = 40
You are correct.

Answer 4

it is like this
+14-17+34+x+21 = 40-12
52+x = 28

x = 28-52

x = -24

Answer 5

14 -17 + 34 + x + 21 = 40
52 + x = 40
x= -12

so yes your answer is correct

(To all you ppl who said 24, that -12 is not part of the sum, it's her answer)

Answer 6

Answer 7
