Answer:$90
Step-by-step explanation:
how much they sell for $95 minus how much they cost $65 equals $30 then divid how much rent is $2700 by the $30 equals $90
or
$95-$65=$30
$2700÷$30=90
The illegal values of b are when the denominator equals 0.
So,
gives you (b-4)(b+2)=0
Therefore, b=4 and b=-2, which is answer A.
Answer:
X = 21/4 - 7/4 = 14/4 = 7/2 = 3 and 1/2
Step-by-step explanation:
X + (2 and 1/2) - 3/4 = 5 and 1/4
X + 2 and 2/4 - 3/4 = 5 and 1/4 <--- common denominator
X + 10/4 - 3/4 = 21/4
X + 7/4 = 21/4
X = 21/4 - 7/4 = 14/4 = 7/2 = 3 and 1/2
