Answer:
B (2 violet)
Step-by-step explanation:
Let the colors be represented by their first letter. Then the balances give rise to two equation:
o +y +b +v = r +g +b
o +y +v = g +v
Subtracting the second equation from the first gives ...
(o +y +b +v) -(o +y +v) = (r +g +b) -(g +v)
b = r +b -v
Adding v-b to both sides, we have ...
b +(v -b) = r +b -v +(v -b)
v = r
Multiplying this result by 2, we can match the final balance:
2r = 2v . . . . . . . choice B

Answer:
6/5m
or
1 1/5m
Step-by-step explanation:
5 - 3 4/5 = x
5/1 - 19/5 = x
5/1(5/5) - 19/5 = x
25/5 - 19/5 = x
25/5 - 19/5 = 6/5
x = 6/5 or 1 1/5
Answer:
Part 8) B.F=0.5 units
Part 9) A.B=2 units
Step-by-step explanation:
we have
The diameter of circle F is 5 units
so
The radius of circle F is r.f=5/2=2.5 units
The diameter of circle G is 6 units
so
The radius of circle G is r.g=6/2=3 units
Part 8) Find B.F
we know that
B.F=G.B-F.G
we have
G.B=rg=3 units
FG=rf=2.5 units
substitute the values
B.F=3-2.5=0.5 units
Part 9) Find A.B
we know that
A.B=A.F-B.F
we have
A.F=r.f=2.5 units
B.F=0.5 units
substitute the values
A.B=2.5-0.5=2 units
