Parallel lines intersect to form a 90 degree angle. true or false?

2. Multiplying a number by 8 and then subtracting 10 from it is the same as tripling the number and adding 5 to it. What is the number?Parallel lines intersect to form a 90 degree angle. true or false?
1. False





2. 3





Using algebra:





8x - 10 = 3x + 5


5x -15 = 0


5x = 15


Therefore x = 3Parallel lines intersect to form a 90 degree angle. true or false?
Parallel lines never intersect. False.


2. Easy Algebra Question:





Set the problem up like this.





Let x be the number


8x - 10 = 3x + 5





8x - 3x = 10 + 5


5x = 15


x = 3


The number is 3. Easy enough.
false, parallel lines will, by definition, never intersect.





(x * 8) - 10 = 3x +5


8x - 10 = 3x + 5


8x - 3x = 5 + 10


5x = 15


x = 3
If the lines are parallel then they will not intersect. ====== (those equal signs are parallel)


2. let n be the number


8n - 10 = 3n +5


8n- 3n = 5 + 10


5n = 15


n = 15/5


n = 3
parallel lines never intersect


2. the number is 3
3





3X8=24 24-10=14


3X3=9 9+5=14








so the answer is 3
