the perimeter is 18.7 units
Answer:
The slope of the equation is -1, so the slope for the parallel line will also be -1.
Step-by-step explanation:
Well, first you'd have to get the x by it's self.
10x+1=3x+9
Subtract 3x from each side and you'll have the x on only one side rather than two.
7x+1=9
Now I'd get rid of the 1 on the x's side. So just subtract 1 from each side.
7x=8
Then you should make it so the seven isn't there with the x either. Just divide each side by 7.
Answer: x=8/7
Each time you change something on one side, you must do the same to the other side. T find the value of a variable in an equation, simple seclude it so it's on it's own without number to make things confusing.
The answer was x=8/7 btw.
Yes they are equivalent, because they both do 30 jumping jacks per minute. If you divide 60/2=30 & 150/5=30. Hope this helps!
