Given:
The given expression is:

To find:
The single logarithm expression for the given expression.
Solution:
Quotient property of logarithm:

We have,

Using quotient property of logarithm, we get


Therefore, the required expression is
.
1. Use the exterior angle theorem that states that an exterior angle in a triangle is equal to its two remote interior angles.
x+46=84
x=38 degrees
2. There are two parallel lines cut by transversal. We can see a same side interior relationship.
3x-5+90+2x=180
5x=95
x=19 degrees
3. Use exterior angle theorem again.
90+34=x+72
x=52 degrees
$18 on Backpack $7 on binder. if you turn the percent into a decimal .72 and multiply .72 by 25 you get 18 which is the cost of the backpack. subtract 18 from 25 and you get $7 left meaning the binder was $7
