Answer:
$30
Step-by-step explanation:
If $25 is 100%,
$2.5 is 10%
$0.25 is 1%
$3.75 is 15%
$0.75 is 3%
Then add $25, $3.75 and 0.75 which is also equivalent to 100%+15%+3%=29.5 and if you rounded it up to the nearest cent it is 30
Let, the number = x
Then, x + 72/x = -17
x² + 72 = -17x
x² + 17x + 72 = 0
x² + 8x + 9x + 72 = 0
x(x + 8) 9(x + 8) = 0
(x + 8)(x + 9) = 0
x = -8 OR -9
In short, Your Number would be: Either -9 or -8
Hope this helps!
The answer is either 257,600 or 257,700. I think you need to round up to 127,700.
We know that
the scale (cm/feet)-----------> 1/2
1 in-------------> 2.54 cm
x in---------------> 1 cm
X=1/2.54------> 0.3937 in
so
the new scale (in/feet)------------> 0.3937 in/ 2 feet-------> 0.1969 in/feet
the answer is
0.1969 in/feet
