Answer:
see explanation
Step-by-step explanation:
2 chords intersecting inside a circle , then the product of the parts of one chord is equal to the product of the parts of the other chord.
6
BE × ED = AE × CE , that is
10 × 3x = 12(2x + 1) ← distribute parenthesis by 12
30x = 24x + 12 ( subtract 24x from both sides )
6x = 12 ( divide both sides by 6 )
x = 2
then
ED = 3X = 3(2) = 6
7
RJ × JP = SJ × JQ , that is
6 × 3x = 4(4x + 1) ← distribute parenthesis by 4
18x = 16x + 4 ( subtract 16x from both sides )
2x = 4 ( divide both sides by 2 )
x = 2
then
RP = RJ + JP = 6 + 3x = 6 + 3(2) = 6 + 6 = 12
2x=8
(Divide 2 from both sides)
x=4
Answer:
-178
Step-by-step explanation:
go left of the 0 to -212 then go right toward the 0 34 spaces to -178
I could be wrong but ... I will try to answer
you first find the common factor
4:3 and 9:5
then
4 times 3 is 12
5 times 3 is 15
the ratio is now:
12:9:15
add the numbers up and that would be 36
divide 754 by 36
which is about 20.94444....
multiply 20.94 by 12, 9, and 15
12 would be 251.28
9 would be 188.46
15 would be 314.1
add them together and they would be about 753.84
