So you know that all the angles in a triangle must add up to 180. Therefore, you can make this equation:
[tex](-20x+3)+(-40x+18)+(-15x+9)=180[/tex]
And now just solve for x!
[tex]-75x+30=180\\-75x=160\\x=\frac{160}{-75}\\x=-2.4[/tex]
So, your answer is:
x = -2.4
X = -2.4

Line f Has Slope Of 4/5. Line g is parallel to line f. What is the slope of line g ?
Answers
Answer:
4/5
Step-by-step explanation:
when it is truly parallel, it must have the same slope.
if the lines would be differently steep, they cannot be parallel.
Answer:
slope of line g = [tex]\frac{4}{5}[/tex]
Step-by-step explanation:
Parallel lines have equal slopes.
Then the slope of line g = slope of line f
slope of line g = [tex]\frac{4}{5}[/tex]
What does the slope represent in this graph ?

Answer: The equation has infinitely many solutions.
Step-by-step explanation:
With George's end result of 3=3, you can assume that the equation is set up in such a way that no matter what you plug in, you will get the same number on both sides of the equals sign, which means the solution is valid. Therefore this means that there are an infinite number of solutions.

Answers
explanation:
since every book is priced the same, you can add them together to get 14. x = the cost of one book, but since we don’t know the cost of one book, we use the variable x. so, 14x is equal to the total cost of the order. hope this helped!

Quinn and Logan solved the equation 8(x-5)=8x+40. Quinn said the answer is x=0, Logan said the answer has infinitely many solutions. Who is right? Explain your answer.
Answers
Answer:
Neither of them are right
Step-by-step explanation:
First, let's actually solve this equation:
8 ( x - 5 ) = 8x + 40
Distribute on the left:
8 ( x - 5 )
( 8 x X ) + ( 8 x ( -5 ) )
8x - 40
8x - 40 = 8x + 40
Add 40 to each side:
8x = 8x + 80
Subtract 8x from both sides:
0 = 80
0 ≠ 80
There are no solutions to the equation
