A because 170.10 and 170.1 are the same. All u do is add zeros to the end, until they have the same number of numbers following the decimal, of the shorter number to see if it is bigger or not.
Y and x are directly proportional, as stated by hypothesis. Let's use the rule of three to find y when x = 8.
x=5 --> y=12
x=8 --> y=?
? = (8*12)/5 = 96/5 = 19.2
So y directly varies with x, and y=12 when x = 5, then y=19.2 when x=8.
Hope this Helps! :D
This equation does not factor...
Just solve the equation, x + 0.15x + 0.06x = 15
1.21x = 15,
x = $12.39 (nearly)
The two integers are 22 and 32 (2x+10=54
