(Angle/triangle problem 25points)
What is the value of X?
1 answer:
Answer:
x = 5
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles in the triangle and equate to 180, that is
10x - 4 + 8x + 3 + 91 = 180
18x + 90 = 180 ( subtract 90 from both sides )
18x = 90 ( divide both sides by 18 )
x = 5

Here's how one would solve it:
17 + 3x2 = 6x
17 + 6 = 6x
23 = 6x
x = 23/6
There's only one solution.
There are none. Absolute values are always positive
Answer: x=-2/3
Explanation: Heres what my calculator says!
After you divide it will give you -2/3 :)
T=26
you just add 7 to the other side with 19 which gives you the answer
The equation would be c=42.5x+60
C is cost
X is number of hours
