Answer:
<h2>C. 3x + 80 + 2x = 180</h2>
Step-by-step explanation:
The straight line creates an angle of 180 °.
Therefore from the picture we have the equation:
3x + 80 + 2x = 180 <em>subtract 80 from both sides</em>
5x = 100 <em>divide both sides by 5</em>
x = 20
Answer:
x = 5
Step-by-step explanation:
8x-9=7x+6-2x
We move all terms to the left:
8x-9-(7x+6-2x)=0
We add all the numbers together, and all the variables
8x-(5x+6)-9=0
We get rid of parentheses
8x-5x-6-9=0
We add all the numbers together, and all the variables
3x-15=0
We move all terms containing x to the left, all other terms to the right
3x=15
x=15/3
x = 5
Answer:
No
Step-by-step explanation:
No, because it doesn't make a perfect square
The answer is 2 fishing method and divide both sides by 6
