21,000 = 3400t + 600

Solve for t.

20,400 = 3400t

t = 6 minutes

Answer:

y = 2

Step-by-step explanation:

The mid segment HJ is half of the third side GK , that is

HJ = $\frac{1}{2}$ GK , substitute values

2y = $\frac{1}{2}$ (y + 6) ← multiply both sides by 2 to clear the fraction

4y = y + 6 ( subtract y from both sides )

3y = 6 ( divide both sides by 3 )

y = 2
