7.55 as a common fraction would be 7 11/20, because 0.55 as a fraction is 55/100, which, when you divide by 5, can be simplified to 11/20, which you can then put next to the 7.
7.55 as a whole number would be 8, because you need to round and since the first decimal place is 5, you round upwards and get 8.

I hope this helps!

448 = -5v + 8(-5 - 7v)<br> What is v?

Answer:

v = -8

Step-by-step explanation:

First we would have to distribute the 8(-5 - 7v). To do this we would multiply 8 by -5 and 8 by -7v to get $448=-5v-40-56v$ . After this, we would have to simplify like terms by subtracting 56v from -5v to get $448=-61v-40$ . We now have to get the variable on one side and to do that, we can add 40 to both sides to get $488=-61v$ . Finally to get the variable alone, we would have to divide both sides by -61 to get $v=-8$ .
