Every day, the volume increases by 24 1/2+15 1/4=39 3/4 gallons. So after 5 days, the volume increases by 39 3/4 * 5 = 795/4= 198.75 gallons
Answer:
The first piece is 5 inches long, while the second is 15 inches and the third one is 20 inches.
Step-by-step explanation:
To determine the length of the 3 pieces, knowing that the total of the board is 40 inches, and that the second measures 3 times more than the first and the third measures 4 times more than the first, the following equation must be performed:
X + 3X + 4X = 40
8X = 40
X = 40/8
X = 5
Therefore, the first piece is 5 inches long, while the second is 15 inches and the third 20 inches.

Step-by-step explanation:
Answer:
The given expressions x+3(7-x) and x+21-3x are equivalent by using the distributive property
Step-by-step explanation:
Given expressions are x+3(7-x) and x+21-3x and also given that they are equivalent
To find for what property the given two expressions are equivalent :
x+3(7-x)=x+3(7)+3(-x)
=x+21-3x ( here we are using the distributive property a(x+y)=ax+ay )
Therefore the given expressions x+3(7-x) and x+21-3x are equivalent by using the distributive property
