the answer for number 3 is 50
Answer:

Step-by-step explanation:
The equation is ,
- Here e is the Euler's Number . The log which are defined on the base e are called Natural logarithms.
Say if we have a expoteintial equation ,
In logarithmic form it is ,

Similarly our required answer will be ,

$793.50, All you do is multiply $15.87 by 50
Answer:
The other angle is 190-7x.
Step-by-step explanation:
Angles in a triangle add up to 180 degrees.
Let A be the third angle.
A + (3x-20) + (4x+10) = 180
A = 180 - (3x - 20) - (4x + 10) = 190 - 7x
I'm assuming it is -m, +m, -m, +m etc..
