For 3 it’s b. For 2 it’s 8. For 4 it’s the whole number
Answer:
37.5
Step-by-step explanation:
The possibilities are:
bbbb
bbbg
bbgg
bggg
This shows that there is a 1 in 4 chance of having three boys and one girl
So the answer could be 1/4 or a 25% chance
Angles of a triangle add up to 180 degrees and then we take away the right angle
180-90=90
5x+5x=10x
90/10=9
x=9
Let
C=Cynthia's age today
A=Abigail's age today
then
at all times
A=C+8......................(1)
twenty years ago,
A-20=3(C-20)
simplifying
A=3C-40...................(2)
Equate (1) and (2),
C+8=3C-40
8+40=3C-C
C=24
=>
A=32
Check: A-C=8... ok A-20=12 C-20=4 => (A-20)=3(C-20) ...ok
Answer:
Abigail is 32, Cynthia is 24.
