I am pretty sure the answer is A because the graph is a cubic function
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.
Answer: 350km
Step-by-step explanation:
Since we are informed that the scale of map is 1cm : 70km. Therefore, the actual distance between towns that are 5cm apart on the map will be:
= 5 × 70km
= 350km
Therefore, the answer is 350km
Answer:
0.75 or 3/4
Step-by-step explanation:
The sum of 1/2 and 1/2 is 1. (1/2 + 1/2 = 1)
The product of 1/2 and 1/2 is (1*1)/(2*2) = 1/4.
If you subtract 1/4 from 1, you get 3/4.
