A ton is 2000 lbs. If a polar bear is 1600 lbs then the fractional part of a ton would be...
1600/2000 which will reduce to
16/20 = 4/5
Do recall that squaring and the *radical sign* cancel each other out... like so:(

)

= a
When you put it that way, it isn't enough :P
(

)

= a
(

)

=?
so you start with
(

)

=

8x+1=25 <-- subtract 1 to both sides
8x=24 <- divide 8 to both sides
x= 3
To find out if it's an extraneous solution ask yourself: It mustn't result in a radical that I like to call... 'illegal'. Plug it into the radicand 8x+1 and make sure you get something that is not a negative number.... so, DO you get a negative number when you plug in x = 3 into the radicand?
(extraneous solution is a invalid solution)
x=3 not extraneous
Answer:
23 cupcakes
Step-by-step explanation:
Volume is the key to this question;
Calculate the volume of the cupcake;
3 × 3 × 3 = 27 inches^3
Then the volume of the box;
15 × 7 × 6 = 630 inches^3
Then divide the volume of the box by the volume of the cupcake to see how many can fit in;
630 ÷ 27 = 23.3333
;Hence you can fit... 23 cupcakes
