Log of 2x cube - log x = log 16 +log x

Use the identities!

Log 2x square = log 16x
2x square = 16 x
2x sqr - 16x = 0
2x(x-8) = 0
X = 0 or 8
According to logarithms x can’t be 0 so it’s 8

If you divide 16 by 2 you get 8, so, 8 teams payed $50, while the other half payed $60.

Hope this helps.  ^_^


(If you're gonna add them up it's 8x60=480 + 8x50=400=880)  :P

Answer:

<em>x=60°</em>

<em>x=48°</em>

<em>x=21°</em>

Step-by-step explanation:

<u>Inequalities</u>

The sum of the exterior and the interior angle of a triangle is 180°.

The measure of an exterior angle of a triangle is called x, thus the interior angle is 180-x.

This angle is said to be at least twice x, thus:

180 - x ≥ 2x

Adding x:

180 ≥ 3x

Dividing by 3:

60 ≥ x

Swapping the inequality:

x ≤ 60°

The measure of x must be less or equal to 60°.

Three possible solutions are:

x=60°

x=48°

x=21°
