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.
Translation please!
Hope this helps!
Maybe you could get a translation app.
<span> supplementary angles have sum = 180
so answer is </span><span>B. supplementary angles</span>
Answer:
1
Step-by-step explanation:
Please use parentheses around the coordinates of your points:
(1, 4); (0.5, 3.5), etc.
If we go from (0.5, 3.5) to (1, 4), x increases by 0.5 and y increases by 0.5.
Thus the slope is m = rise / run = 1/1 = 1.
This is the average rate of change for the sequence shown.
