If a ten a ten a ten a ten a ten B = 270,1: B ten a ten a ten a ten B = 290,2: then a ten B = ()
one hundred and twenty
A 10 a 10 a 10 B 10 B 2 6.4, a 10 a 10 B 10 B 2 5.6, find a 10 B 2? B-A 2?
2.8 and 1.2
A + B is equal to 102 A-B is equal to 103 a multiplied by B is equal to 104 a divided by B is equal to 10 A
The following expression shows that the two quantities a and B are in positive proportion, and the formula is (4 a divided by B equals 10)
1 A + B equals 10 2 A-B equals 10 3 a times b equals 10 4 a divided by B equals 10
