If m∡J=30, then 2(m∡J) = 2(30) = 60
Answer:
1/6 has been vacummed.
Step-by-step explanation:
Answer:
-5
Step-by-step explanation:
ab = dc
x+15= 3x+25
2x = -10
x = -5
substituting in ad and bc
-10+18 = 8
3-(-5)=3+5=8
The answer is a. the first step is to divide the whole bottom equation by -1 because x can’t be negative. you then plug in y + 9 into the first equation to solve. so the equation would be (y + 9) + y = 11. you do this because in substitution you plug in one of the equations into the other equation. you then get 2y + 9= 11. you would next subtract 9 to both sides which leaves you with 2y= 2, divide by both sides, y = 1. you then plug the why value into the first equation to figure out the value for x. so it would be x + 1 = 11, subtract 1, x equals 10.
sorry this was hard to explain! hope this helps!
This is an example of a Circle Graph, a circle graph is like a Pie chart, and In graph theory, a circle graph is the intersection graph of a set of
chords of a circle. That is, it is an undirected graph whose vertices
can be associated with chords of a circle such that two vertices are
adjacent if and only if the corresponding chords cross each other.
Look at the graph I showed you
