Answer:
Tim wants to knows the opposite of how cold it is outside. If the temperature outside is 0 degrees Celsius, what is the opposite of it?
Step-by-step explanation:
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.
6 seconds = 540 m
-----------------------------
Find 1 second:
-----------------------------
6 sec = 540 m
1 sec = 540 ÷ 6
1 sec = 90m
-----------------------------
Find 4 seconds:
-----------------------------
1 sec = 90m
4 sec = 90 x 4
4 sec = 360 m
----------------------------------------------------------
Answer: It can travel 360m in 4 seconds.

The answer is going to be 15
Answer:
7.2 km
Step-by-step explanation:
Distance between Brookfield to Seaside = 20.4 km
Distance between Yardley and Seaside = 13.2 km
Let distance between Brookfield to Yardley be x.
Thus:
x + 13.2 km = 20.4 km
Subtract 13.2 from each side
x = 20.4 - 13.2
x = 7.2
Distance from Brookfield to Yardley is 7.2 km
