THIS IS SO EASY!
Use the method of "Writing it as a sum". (meaning use addition signs.)
Use commutative property (Change order of expression of the same signs).
How to solve:
1.) They are all negatives so add.
-24 + (-26) + (-8)
-24 + - 26 + -8 They all have the same signs)
-50 + -8
-58
When you are writing it as a sum, you're basically adding it's additive inverse.

Rate x time = distance
b = rate boat travels in still water
c = rate of the current
(b-c)4 = 216
(b+c)4 = 304
4b - 4c = 216
4b + 4c = 304
___________
8b = 520
b = 65 Km/hr
4c = 304 - 4b = 304 - 260 = 44
c = 11 Km/hr
Answer:
+ closed
- closed
* closed
÷ not closed
Step-by-step explanation:
When you add integers, you will always get an integer so it is closed under addition
When you subtract integers, you will always get an integer so it is closed under subtraction
When you multiply integers, you will always get an integer so it is closed under multiplication
When you divide integers, you will not always get an integer so it is not closed under division
1/5 = .2 which is not an integer
