Answer :
Answer:
B = 23
Step-by-step explanation:
121.66 = 2.15h + 72.21
To Begin, use the additive property of number:
Subtract 72.21 from each side. The RHS and the LHS
121.66 - 72.21 = 2.15h + 72.21 - 72.21
49.45 = 2.15h
Then Divide both sides by the coefficient of 'h'
(49.45) / 2.15 = (2.15)h / 2.15
Simplifying further becomes:
h = 49.45 / 2.15
h = 23
