8 Students are not enrolled. Reason being 9 are taking German and 9 are taking Spanish so 9+9= 18 but because 3 are taking both you subtract 3 so that would give you 15 and 23-15=8

The answer is 69.27272727
Answer:
Option T - Lowest
Option R - Highest
Option S - Neither
Explanation:
Option T $334.43 x 48 = $16,052.64 -- adding $52.64 in interest
Option R $203.67 x 72 = $14,664.24 -- adding $664.24 in interest
Option S $256.24 x 60 = $15,374.4 -- adding $374.4 in interest.
T = $52.64 (Lowest)
R = $664.24 (Highest)
S = $374.4 (Middle)
Answer:
The answer is
Speed of the boat in still water= 12mph
Speed of current= 9mph
Step-by-step explanation:
<em>let x= speed of the boat in still water</em>
<em>let y= speed of current</em>
<em></em>
<em>DATA WE HAVE</em>
<em>with current </em>
<em>rate- x+y </em>
<em>time- 6 hours</em>
<em>distance- 126 miles</em>
rate= 126/6= 21
against current
rate- x-y
time- 42hr
distance- 126 miles
126/42= 3
Now, we add these two equations vertically.
<em>x-y=3</em>
<em>+</em>
<em>x+y=21 </em>
<em>2x = 24</em>
<em>Now we divide each side by 2</em>
<em>2x/2 24/2</em>
<em>x= 12</em>
<u><em>The speed of the boat in still water is 12mph</em></u>
<em></em>
<em>NOW WE HAVE HALF OF THE ANSWER</em>
if x+y= 21
then
12+y=21
subtract 12 from both sides
y=9
<em><u>The speed of the current is 9mph</u></em>
<em><u /></em>
<em><u>Checking)</u></em>
<em><u>12+9=?21</u></em>
<em><u>21=21</u></em>
<em><u>12-9=?3</u></em>
<em><u>3=3</u></em>
<em><u /></em>
