Answer
A
Step-by-step explanation:
$\mathrm{Convert\:mixed\:numbers\:to\:improper\:fractions}:\quad6\frac{2}{3}=\frac{20}{3}$
=8\div \frac{20}{3}
=\frac{8}{1}\div \frac{20}{3}
=\frac{8}{1}\times \frac{3}{20}
=\frac{2}{1}\times \frac{3}{5}
=\frac{2\times \:3}{1\times \:5}
=\frac{6}{1\times \:5}
=\frac{6}{5}
Convert improper fractions to mixed numbers
=1\frac{1}{5}

Answer:
6
Step-by-step explanation:
It is ALWAYS helpful to sketch the appropriate figure.
That will make clear that 3x = x+4, by the definition of midpoint.
Then you solve the equation and you get x=2, so that PQ = 6.
One number = x
Another number = y
x = y + 5
x + y = 37
(y + 5) + y = 37
2y + 5 = 37
2y = 32
y = 16
x = (16) + 5
x = 21
The numbers are 16 and 21.
