B. -25, because 1 minus 20 is -19, then you subtract 6 from -19, then the answer is -25.

1 - r - a      r=20    a =6
1 - 20 - 6 
  -19 - 6 =  -19 + (-6) 
     -25 would be the answer

Can someone help me I need help with this question
malfutka [58]
To find the difference of 5 1/8 and 2 1/5 I would first turn the mixed numbers into improper fractions. Therefore, I would have 41/8 - 11/5. Then, I would find a common denominator which would be 40. I would have 205/40 - 88/40 and I would end up with 117/40. 

Can you please help me answer my question? I already asked it but it hasn't been answered. It is fro social studies: What were some accomplishments of Montezuma?
