Answer:
300 cm^2
Step-by-step explanation:
The volume of the rectangular prism is calculated by multplying lenght to the widht to the height
20*15*10 = 300 cm^2
Sum means add.
So, we'd need to add
4 5/6 + 3 5/6
5/6 + 5/6 = 10/6, or 1 4/6, or 1 2/3.
4 + 3 = 7
7 + 1 =8
8 2/3 is your answer.
Glad I could help, and good luck!
Complete question :
A 48 inch board in to be cut into three pieces so that the second piece is twice as long as the first, and the third piece in 3 times as long as the first. If x represents the length of the first, find the lengths of all three
Answer:
Length of first piece = x = 8
Length of second = 2x = 8*2 = 16
Length of third = 3x = 8 * 3 = 24
Step-by-step explanation:
Let :
Length of first piece = x
Length of second = 2x
Length of third = 3x
The total lengtb of board = 48 inches
Hence,
First + second + third = 48
x + 2x + 3x = 48
6x = 48
x = 48 / 6
x = 8
Length of first piece = x = 8
Length of second = 2x = 8*2 = 16
Length of third = 3x = 8 * 3 = 24
-3= 6(-1) + b
-3= -6+b
3=b
B is 3
