you would have to find the other value of the ratio.

If you look at the original ratio of 5:4, you can tell that 45 is just 8×5 and therefore you can also multiply 4×8 which would 32.

Consider U = {x|x is a real number}. A = {x|x ∈ U and x + 2 &gt; 10} B = {x|x ∈ U and 2x &gt; 10} Which statements are true? 5 ∉
-Dominant- [34]

x+2 > 10 solves to x > 8 after we subtract 2 from both sides

So set A is the set of real numbers that are larger than 8. The value 8 itself is not in set A. The same can be said about 5 as well.


Set B is the set of values that are larger than 5 since 2x > 10 turns into x > 5 after dividing both sides by 2. The value x = 5 is not in set B since x > 5 would turn into 5 > 5 which is false. The values x = 6, x = 8, and x = 9 are in set B.


----------------


Summarizing everything, we can say...

5 is not in set A. True

5 is in set B. False

6 is in set A. False

6 is not in set B. False

8 is not in set A. True

8 is in set B. True

9 is in set A. True

9 is not in set B. False
