Answer:
A.) $2.52 less per pound. B.) $13.08 more
Step-by-step explanation:
A.) You pay $14.82 for 1.5 lbs of ham. You divide $14.82 by 1.5 lbs (14.82/1.5) to figure out how much you spend per pound of ham. You should get $9.88. Since you spend $12.40 per pound of roast beef, you subtract $9.88 from $12.40 ($12.40 - $9.88). You should get $2.52, which is your answer.
B.) Since you paid $14.82 for 1.5 lbs of ham, you already have this variable. Take the 2.25 lbs of roast beef and multiply it by $12.40 per pound (12.40*2.25). You then take that number ($27.90) and subtract it by $14.82 (27.90-14.82) and you should get your answer, $13.08.

Answer:
Simplifying
an = 8n + -7
Reorder the terms:
an = -7 + 8n
Solving
an = -7 + 8n
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Divide each side by 'n'.
a = -7n-1 + 8
Simplifying
a = -7n-1 + 8
Reorder the terms:
a = 8 + -7n-1
Answer:
Step-by-step explanation:
because -3 is a zero, so x=-3
(k-1)(-3)²+k(-3)+1=0
9(k-1)-3k+1=0
9k-9-3k+1=0
6k=8
3k=4
k=4/3
(B)
∵ x=-1 is a zero of p(x)=kx²-4x+k
so k(-1)²-4(-1)+(-1)=0
k+4-1=0
k=-3
