First, add 2 to both sides. You should have 3/2x=21. Multiply both sides by 2 which gives you 3x= 42. Divide by 3 and you have x=14
Answer:
Buying 3 cans individually.
Step-by-step explanation:
If you bought 3 cans for 1.50 it would be 4.50.
If you bought a triple pack it would be 5 dollars.
So 4.50 is less than 5 dollars.
Hope this helps!
Answer:
40
Step-by-step explanation:
Let the numbers be 2x and 3x
Then their L.C.M. = 6x
BUT also their LCM=48
6x=48
x=48/6
x=8
So,
First number=2x=2x8=16
Second number=3x=3x8=24
The numbers are 16 and 24.
Hence required sum =(16+24)=40
So none of the options are correct
Speed = Distance/Time
So, speed
= 300 km/2h
= 150km/h
= (150 × 1000m) / 3600s
= 150000m/3600s
= 41.66m/s [approximately]
