Answer:
<em>x=3</em>
Step-by-step explanation:
<u>Angles and Lines</u>
We must recall:
- The sum of the internal angles of a triangle is 180°
- Two linear angles add up to 180°
The image shows a triangle and the extension of its base to form two linear angles.
Note from the triangle, angle R is what it takes to get to 180°:
From the line SQ, angle R what it takes to get to 180°. Thus:
Equating:
Subtracting 180 and simplifying:
Dividing by 19:
x=3
Answer:
-15x + 30
Step-by-step explanation:
-3(5x -10)
-15x + 30
Answer:
The answer is 37.
Step-by-step explanation:
First of all we use Pemdas. Add the parantheses first. So its 7-18(-5/3) then you multiple the -18 to 5/3 Because after Parantheses its Exponents multiplication. So it becomes 30. Then you add 7 to get 37. I hope this is helpful.

Answer:
C. x = 3.71
Step-by-step explanation:
4 + 9(ln x) = 15.8
Subtract 4 from both sides.
9(ln x) = 11.8
Divide both sides by 9.
ln x = 11.8/9
x = e^(11.8/9)
x = 3.71
