I don't have an idea about the 1st one but second one goes by subtracting 1/3
subtract 1/3 from 8 1/3 it's 8, subtract 1/4 from 8 it's 7 2/3. figuring out the patterns are simple most of the time bu you can get stuck sometimes, if you wanna get better, practice...

You can work out the pattern by subtracting the first number from the second. So for the first one, 7 1/2 (Which is equal to 7 2/4, because 1/2 = 2/4) - 7 1/4 = 1/4, so you add a quarter each time
For the second one, 8 - 8 1/3 = -(1/3), so you subtract a third each time
Hope that helps and isn't too confusing!

448 = -5v + 8(-5 - 7v) 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 $v=-8$ .
