fill in the blank

Answer 2

well i have no idea what any of this is. so thats why im asking for help

Answer 3

just ignore everything else for now and focus on these numbers, like an ordinary math problem

Answer 4

42 --> 0 + ___

what number needs to go into the blank to make both sides equal?

Answer 5

ummmmm. this is sad, i have no idea

Answer 6

pretend the arrow is an equal sign.

Answer 7

42 = 0 + ___

what number goes into the blank?

Answer 8

sorry my mind is going everywhere right now and i cant even think

Answer 9

subtract 0 from both sides

Answer 10

42 - 0 = ?

Answer 11

42

Answer 12

good!

so we go from:

42 = 0 + ___

to

42 = ___

Answer 13

meaning that the number in the blank is 42

Answer 14

42 = 0 + 42

Answer 15

now we repeat the same process but with the bottom numbers

Answer 16

19 = -1 + ___

what number goes into the blank?

Answer 17

18 ?

Answer 18

nope

Answer 19

it might be helpful to re-arrange the problem

__ - 1 = 19

what goes into the blank?

Answer 20

is it -19 ? or do i do it different then the last one

Answer 21

maybe it would be better if i used a variable?

x - 1 = 19

what does x = ?

Answer 22

that's worst . 0? i dont know

Answer 23

maybe a word problem?

My sister takes away 1 of my marbles. Now, I have 19. How many did I have before she came?

Answer 24

20 i guess

Answer 25

good!

so the number in the blank is 20 because

__ - 1 = 19
20 - 1 = 19

Answer 26

here's what we have so far

Answer 27

now, the lower number (20) represents the number of electrons the element has

which element has 20 electrons? (use a periodic table)

Answer 28

okay so 42 and 20.

Answer 29

like CA ? or something else

Answer 30

good! Ca (a is lowercase)

Answer 31

so in the blank, you write:

Answer 32

and this entire thing goes into the blank in question 1

Answer 33

oh wow! okay the wasnt that hard

Answer 34

yeah

the second equation is a tricky one. since the numbers and element don't change, you always write a gamma particle in the blank

Answer 35

the other ones can be solved using the same method the first problem

Answer 36

actually it looks more like this
