what part of the scientific method involves drawing inferences about experimental results and determining if the collected data support the original hypothesis?

Drawing Conclusions

Explanation:

You put together your observations and can finally decide if your hypothesis was right or not.

that tool would be a compass

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
