Answer:
12
Step-by-step explanation:
Answer: we multiply the second equation by -2. This property is the multiplication property of equality (1).
Then, we add the two equations generated. (2) addition property of inequality.
Next, we divide both sides of the equation by 13. That is division property of inequality.
Moreover, we substitute the value obtained for y in the first equation. This is substitution property of equality.
Then, we simplify
Next, we add +3 to both sides of the equation in order to have an equation with only one side having a variable. That is addition property of equality.
Lastly, we divide both sides of the equation by 4. This is division property of equality.

Answer:
429 beats
Step-by-step explanation:
The number of beats is proportional to the time of the song.
Convert the time to seconds to avoid recurring decimals.
4 minutes 12 seconds = 4×60+12=252 seconds
3 minutes 54 seconds = 4×60−6=234
seconds
Set up a direct proportion using equivalent fractions:
x234=462/252
←beats/←seconds
x=234×462/252
x=429 beats
Answer:
303.5 pounds
Step-by-step explanation:
If all the pallets weigh 4,856 together and each pallet weighs the same since they have equal cement and cement weight is equal, then 16 pallets will weigh 303.5 pounds each.
This is true because 4,856 / 16 = 303.5.
The required values are :
Length = 33 m
Breadth (width) = 30 m
