Basically, this is saying that 80% of (x) = 2 so you have know what the whole would be. It would be 2.5 because 80% of 2.5 is 2. So because you are subtracting 7 from v to get 2.5, you have to add 2.5 to 7 to get v. V=9.5
Plates needed=(b+c)/p
Let's say she has a total of 70 buns and cookies. And she wants to put 5 of one or the other on each plate. Then, she needs 70/5, or 14 plates

answer:
statements
1. <5 = <6
2. <4 + <5 = 180
3. <4 + <6 = 180
reasons
1. given
2. definition of linear pair
3. substitution
step-by-step explanation:
- i have written the statements and reasons seperately so just put them in the order i have
- in a proof we always put the given first
- now, we can see that <4 and <5 are "together" in a straight line, therefore they are linear pairs
- linear pairs add up to 180 (always)
- now that we have that, we can use susbtitution to get the answer want/prove what we want to prove
If 100 cats killed 100 mice in 100 days, you can say that each cat killed one mouse the day after the last cat. So, if four cats killed four mice, and we're going of off the same basis that each cat killed one mouse the day after the last cat, then the answer would be 4.
