You can buy 2 DVDs for the same price you would pay for 3 CDs selling for $13.20 a piece.Explain how you could find the price of 1 DVD.

Answers

So,

3 CD's sell for $13.20 each.
3 * 13.20 = $39.60

$39.60 is also the price for 2 DVD's.

Divide $39.60 by 2.
$19.80

Each DVD is $19.80.

Kendra says that she can draw <A and <B so that m <A is 119° and <A and <B are complementary angles. do you agree or disagree? explain your reasoning.

Answers

I disagree, because if angle A and B make complementary angles then both the measures added should equal 90 degrees. However, m<A is 119 so it cannot be complementary making the statement false.

A quadrilateral has angle measures of 102°, 84°, and 77°. What is the measure of the fourth angle?

Answers

Answer:

Measure of the 4th angle = 360-(102+84+77)

= 360-263

= 97°

Hope this helps!

log (7x-10)=2

Use the identity: loga(x)=b = x=(a)(b)

7x-10=10^2

Evaluate the Power

7x-10=100

Addition Property of Equality

7x=110

Division Property of Equality

x=110/7 or 15.7143

2. Answer: 0.3107

log(3)+log(x^-3)=2
log(3x^-3)=2
log(3 x 1/x^3)=2
log(3/x^3)=2
3/x^3=10^2
3/x^3=100
3=100x^3
3/100=x^3
Answer Cube root 30 / 10 or 0.3107
