gravity on Earth is 9.8 m / s / a ^ 2 + gravity on the moon is 1.6 m / s / power of two so if the mass of an object on earth is 40kg its mass on the moon is blank kilograms and its weight on the moon is blank Newtons

Yes she is correct. the answer is completely correct

the catch is that the top numbers are atomic masses the bottom numbers are the numbers of protons and electrons in an uncharged atom. they are the number of that atoms as you would find them on the periodic table. further, the numbers on the left are used to determine the missing numbers on the right

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
