Answer:
A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). This article reviews all three cases. One solution. A system of linear equations has one solution when the graphs intersect at a point. No solution.
Step-by-step explanation:
The least common denominator of 1/6 and 7/9 is 18. Why? Well, we can start by listing the multiples of both denominators (the numbers on the bottom of the fractions) which are 6 and 9.
Multiples of 6:
6, 12, 18, 24, 30, 36, 42, 48, 54, 60
Multiples of 9:
9, 18, 27, 36, 45, 54, 63, 72, 81, 90
By identifying the multiples of these numbers, we can see that the lowest multiple these integers have in common is 18. Because of this, the least common denominator of 1/6 and 7/9 is 18.
Your final answer: 18.
In a kite, all of the angles added together equal 360. You already know there are two right angles, and because of this, you would subtract 180 from the 360, leaving you with 180. In order to solve for x, you have to add 18x-2 to 12x+2 and set it equal to 180. Your equation would be 18x - 2 + 12x + 2 = 180. The 2's would cancel out, leaving you with 18x + 12x = 180, 30x = 180, then 6 = x.
