Answer:
n=6
Step-by-step explanation:
Consider the diagram below
Using the Theorem of Intersecting Chords
AE X ED= BE X EC
5 X n = 2 X 15
5n =30
n= 30/5 = 6
First you would distribute the 3. So it would be (3x+6)+14+7x. Since you can’t do anything inside the parentheses, you drop them. Then you’d combine like terms. 3x+7x is 10x, and 14+6 is 20. That would get you your answer, 10x+20
Answer:
X=65
Y=40
Step-by-step explanation:
2x+10=140
-10 -10
2x=130
÷2 ÷2
x=65
Y=180-140
Y=40
-x on both sides to get
x=15
C- 3/8 because it converts to .375
