The total weight of three tables is 16.9 pounds. The first table is twice as heavy as the second table and the weight of the thi

gavmur [86]

X the 1st table
y the second
z the third

The equation is : x+y+z =16.9

But we know (given) that x=2y & z=(1/3)y

Calculate everything in term of x:

x= 2y==> x/2 =y

z=(1/3)y ==> & since y=x/2 then z= (1/3)(x/2)==> z=x/6; y=5.07 & z =1.69

x + x/2 + x/6 = 16.9===>1.666x = 16.9===> x= 10.14
