FrozenT [24]

Answer:

$t=480$

Step-by-step explanation:

Given

$-100 = -\frac{t}{5} - 4$

Required

Solve for t

$-100 = -\frac{t}{5} - 4$

Add 4 to both sides

$4-100 = -\frac{t}{5} - 4+4$

$4-100 = -\frac{t}{5}$

$-96 = -\frac{t}{5}$

Multiply both sides by -5

$-5*-96 = -\frac{t}{5} *-5$

$-5*-96 = t$

$480 = t$

$t=480$
