Step-by-step explanation:
they have no other common factors
g - 3/7 = 2/7 is an equation.

Answer: 30 dominoes in total.
Step-by-step explanation:
Each line is 21 inches long.
the space between dominoes is 1 + 1/2 inches.
(assuming that the distance includes the domino itself) Now, we need at least two dominoes to see this distance,
The we have N + 1 dominoes per line, and the distance is:
N*(1 + 1/2)inches = 21 inches
If we find N, we can find the number of domineoes in each line:
N = 21/(1 + 1/2) = 14
This means that we have 14 + 1 = 15 dominoes in each line, and we have two lines, so we have 30 dominoes in total.
Make the equations equal to each other to find x.
21.2x+c=5.3(4x-4.6)
Now distribute.
21.2x+c=21.2x-24.38
So c= -24.38
