Answer:
30
Step-by-step explanation:
y/x = 30/(x + 10)
(y + 12)/x = 54/(x + 10)
y/x + 12/x = 54/(x + 10)
30/(x + 10) + 12/x = 54/(x + 10)
30x + 12(x + 10) = 54x
30x + 12x + 120 = 54x
120 = 12x
x = 10
EG = x + x + 10
EG = 10 + 10 + 10
EG = 30
40 hundreds flats. 400 tens = 4,000. 40 hundreds also equals 4,000.
Step-by-step explanation:
1.before starting first collect the like terms.
