Answer:
10=x
Step-by-step explanation:
Intersecting Chords Formula:(segment piece) x (segment piece) =
(segment piece) x (segment piece)
6*5 = 3*x
30 = 3x
Divide by 3
30/3 = 3x/3
10 =x
Answer:
D
Step-by-step explanation:
Hello!
Answer:
First, write 0.63 as 0.63/1
Then, multiply both numerator and denominator by 10 for every number after the decimal point.
0.63x100/1x100=63/100
so your answer is 63/100 :)

Answer:
(15/2, -5/2)
Step-by-step explanation:
1. Sub x=5y+20 into 2x+2y=10 and simplify as shown below.
2(5y+20)+2y=10
10y+40+2y=10
12y+40=10
12y=-30
y=-30/12
y=-5/2
2. Sub in y=-5/2 into 2x+2y=10 to find x and simplify as shown below.
2x+2(-5/2)=10
2x-5=10
2x=15
x=15/2
