You have $65.00 in birthday money and want to buy some CDs and a DVD. Suppose a DVD cost $15.00 and a CD cost $12.00. Write an inequality to find
out how many CDs you can buy along with one DVD. Solve the inequality.

1 dvd and 4 cds

Step-by-step explanation:

If you have $65.00 and 1 dvd costs $15.00 that leaves you with $50.00 and each CD costs $12.00 just multiply by 12s until you get to 50 or close so there you can buy 4 CDs and have 2$ left.

you would use (d.) the law of cosines or a^2 = b^2 + c^2 – 2bc(cos a)

, b^2 = a^2 + c^2 – 2ac(cos b), or c^2 = a^2 + b^2 - 2ab(cos c). you wouldn't use b. the law of sines as it is mostly effective when 1side and 2angles are given. a and c aren't the answer for they are the improper versions of the law of cosines. hope this is .

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
