Answer:

Step-by-step explanation:

Answer:
length = 13 ft
Width = 3 ft
Step-by-step explanation:
Width = w ft
Length = ( w +10 ) ft
Area = 39 square ft
length * width = 39
(w +10)* w = 39
w *w + 10*w = 39
w² + 10w - 39 = 0
w² + 13w - 3w - 3*13 = 0
w(w + 13) - 3(w + 13) = 0
(w + 13) (w - 3) = 0 {Ignore w + 13 , as measurement cannot be in negative}
w - 3 = 0
w = 3
length = 3 +10 = 13 ft
If you would like to divide 2/3 by 1/2, you can do this using the following step:
2/3 / 1/2 = 2/3 * 2/1 = 4/3 = 1 1/3
The correct result would be 1 1/3.
Answer:
Step-by-step explanation:
Both expression are the same :
14 = 2(x + 3)
By expansion :
14 = 2*x + 2*3
14 = 2x + 6
Hence ;
Both expression are the same
Weight of one circle :
Final weight on both sides are equal:
Weight on Left hand side = 14
Weight on right hand side = 3*x + 3*x
Weight on Left hand side = Weight on right hand side
14 = 3x + 3x
14 = 6x
x = 14 / 6
x = 2.333
