To solve the equation 1/2r = 5, we need to isolate the variable r.

To do this, we can multiply both sides of the equation by 2:

(2)(1/2r) = (2)(5)

This simplifies to:

r = 10

Therefore, the solution to the equation is r = 10.

To solve the equation w - 1.2 = 5.78, we need to isolate the variable w.

To do this, we can add 1.2 to both sides of the equation:

w - 1.2 + 1.2 = 5.78 + 1.2

This simplifies to:

w = 6.98

Therefore, the solution to the equation is w = 6.98.

To solve the equation s/3 = 4, we need to isolate the variable s.

To do this, we can multiply both sides of the equation by 3:

(3)(s/3) = (3)(4)

This simplifies to:

s = 12

Therefore, the solution to the equation is s = 12.

To solve the equation d + 17.6 = 31.9, we need to isolate the variable d.

To do this, we can subtract 17.6 from both sides of the equation:

d + 17.6 - 17.6 = 31.9 - 17.6

This simplifies to:

d = 14.3

Therefore, the solution to the equation is d = 14.3.
