Given the statement:
seven and thirty two hundreths plus two and one tenth times two and seven tenths minus 18a
Solution:
The numerical statement can be written in a numerical equation as,
( 7 + 3200) + 2 + 1/10(2 + 7/10) -18a
In order to determine the value of a we transpose - 18a on the other side of the equation, while we combine the similar terms on the other side. We must take note that when transposing a number, the sign changes.
= ( 7 + 3200) + 2 + 1/10(2 + 7/10) -18a
( 7 + 3200) + 2 + 1/10(2 + 7/10) = 18a
3207 + 2 + 2/10 + 7/20 = 18a
Convert the fractions into decimals in order to solve easily.
2/10 = 0.2
7/20 = 0.35
3207 + 2 + 0.2 + 0.35 =18a
3209.55 = 18a
Divide both sides by 18 in order to get the value of a.
a = 178.308
Final answer:
a = 178.308
