The answer would be 11 gallons.
The tub starts with 32 gallons. Every minute it loses 3 gallons.
So after 1 minute it has lost 3 gallons. For example:
32-3= 29 Meaning that after 1 minute the tub has 29 gallons left.
Now you have to remember that the tub is draining for 7 minutes. So it is losing 3 gallons 7 times, because it loses 3 gallons each minute and there are 7 minutes.
We can use multiplication to find how many gallons the tub loses after 7 minutes. This sign “X” basically means “groups of”. We have 7 groups of 3, or
7 X 3
This is the same as saying we have 3, 7 times. Written like this:
3+3 +3 +3 +3 +3 +3 = 21
So after 7 minutes the tub has lost 21 gallons.
Now we take the original number of gallons and take away what was lost:
32-21=11
So there are 11 gallons left after 7 minutes.
Please let me know if you need any further explanation. Hope this helped.

The answer is: 5 .
_____________________
Explanation: The solution is: m <span>> 5 .
___________________________
GIven the answer choices, m would not EQUAL "5", since m is GREATER THAN 5; or, "m </span> > 5 ".
______________
All the other answer choices: 7; 9, and 11, are all greater than 5; so they all could be solutions. The question asked which would NOT be solution for the value of "m". The answer choice given, "5", would not be a solution.
_____________________________________________________
How do we get: " m > 5 " ??
___________________________
We solve for "m"; or simplify; as follows:
______________________________________________________
Given: 12m − 8 <span>> 52 ; Let us simplify to solve for "m";
</span>__________________________
→ Add "8" to both sides;
_______________________
→ 12m − 8 + 8 > 52 + 8 ;
____________________________________________
→ to get: 12m > 60 ; → Now, divide EACH side of the inequality by "12"; to isolate "m" on one side of the equation; and solve for "m" ;
________________________________________________
→ 12m / 12 <span>> 60 / 12 ;
_______________________________________________
</span>→ m > 5 ;

A) 18.5yd
The shadow cast is equal to .5 yards per every yard of object + the actual measurement
•5(12.3)= 6.15
6.15+12.3=18.45
Round up to 18.5
