When you set up equations like this, look at the units for help. They cancel out during division and multiplication like numbers to give desired quantities. Rates can be reversed if need be (3 meters/sec or 1/3 sec/meter).
time × (distance / time) = distance
See.. time/time = 1; leaving distance
Subtract the rate of the opposing walkway...
t × (3 m/s - 1 m/s) = d
2t = d
Answer is then A.
Answer:
3n +3
Step-by-step explanation:
7n-(4n-3)
Distribute the minus sign
7n -4n +3
3n +3
Answer:
-9/2
Step-by-step explanation:
Divide both sides of the equation by 2.
Answer:
63
Step-by-step explanation:
1/3 of 63= 21
and the reverse of 63 is 36
so 1/2 of 36 =18
so 21-18 =3
hence proven
0.6 times 25 = 15
Matthew gets $15
Luke gets $10
Hope this Helps!
