x³+2x²-6x-12=x²•(x+2)-6(x+2)=(x+2)•(x²-6)
X=number of books that cost 0.60
y=number of books that cost 0.75
x+y=16
0.6x+0.75y=10.95
solve
multiply second equation by 10 for nicity
6x+7.5y=109.5
multiply first equesiotn by -6 and add to second
-6x-6y=-96
<u>6x+7.5y=109.5 +</u>
0x+1.5y=13.5
1.5y=13.5
divide both sides by 1.5
y=9
sub back
x+y=16
x+9=16
minus 6
x=7
seven 0.60 books and nine 0.75 books
Answer:
B) M-5
Step-by-step explanation:
the commutative property does not apply to subtraction or division, only addition and multiplication
These are the answer that I got:
A. <span>That means: "The more it costs, the fewer people you can invite."
B. <span>Amount you can spend = M; You will have to come up with this number - whatever you think is reasonable.
</span>
C. (C = Cost per person, P = number of people you can invite )
D. You will have two equations. In the first equation, C will be the per-person cost at the first bowling alley. In the second equation, C will be the per-person cost at the second bowling alley.
E. <span>Be sure to think this through. Yes, you will be able to host more guests at the bowling alley with the lowest per-person cost, but is that the only factor you need to consider? What about location? Quality of lanes and bowling equipment? Music? Food? Customer Service? Consider ALL aspects.</span> You might pick the more expensive bowling alley because you feel would have a better experience, or maybe you don't want to invite lots of people anyway.<span>
Hope this helps!</span>
