Answer: -6.11
Step-by-step explanation:
Subtract.
45.24
- 51.35
----------------
Invert the operation because since the result is a negative number, we cannot operate 51 of 45. Just keep in mind that the result is going to be negative because 51 is bigger than 45.
51.35
- 45.24

-6.11
Answer:
50
Step-by-step explanation:
v = the original speed of the cruise
d = 225 km the distance passed
t = d/v = 225/v the total time of the travel
v*1.5 + (v + 10)(d/v - 1.5 - 0.5) = d (using the formula distance = speed*time)
1.5v + (v + 10)(225/v - 2) = 225
Look at the images to see the solved equation
2x X 54 is going to be 108x
since both are positive you will get a positive #
54 X 2 is 108
Sorry it to hard to help out next times
