Answer:
18
Step-by-step explanation:
10.
( 3 x 3 x 3 ) (3) (5) = 405
and i can't read 11 sorry ):
The number that is halfway between 3/5 and 7/10 is 13/20.
After tax bill = 5*12.80(1+ 0.075)
<span>total = 5*12.80(1+ 0.075) ( 1 + 0.15)= $79.12</span>
(4-x) /(3x+21)
The denominator cannot be zero
3x + 21 ≠ 0
3x ≠ -21
x ≠ -7
The domain of the function will be all real number except -7
{x | x ≠ -7}
