<span>To subtract 7 from 13 you use the fact that 13 is one ten plus three units, i.e. 13 = 10 + 3. then you can subtract 7 from 10 which is 3, and then add the 3 other 3 units to get 3 + 3 = 6. In this way, you have subtracted 7 from 13 using the fact that 13 is one ten plus 3 units.</span><span>

Desert Shores is below the sea level and the difference is more than 600 feet
Answer:
(P, Q) = (-75, 57)
Step-by-step explanation:
The equation will have infinitely many solutions when it is a tautology.
Subtract the right side from the equation:
Px +57 -(-75x +Q) = 0
x(P+75) +(57 -Q) = 0
This will be a tautology (0=0) when ...
P+75 = 0
P = -75
and
57-Q = 0
57 = Q
_____
These values in the original equation make it ...
-75x +57 = -75x +57 . . . . . a tautology, always true
I don’t know, I just need to answer 2 questions before it gives me answers
When dividing three real numbers the order can effect the answer.
Example:
8:4:2
1. 8:4:2=(8:4):2=2:2=1;
2. 8:4:2=8:(4:2)=8:2=4.
As you can see the results are different.
Answer: It is not true.
