The answer is $- 1$ $-1$ .

Simplify: $\frac{s - r}{t}$ $(s-r)/t$ , where $r = - 3$ $r=-3$ , $s = 4$ $s=4$ , and $t = - 7$ $t=-7$

Substitute the values for $r, s$ $r, s$ , and $t$ $t$ into the expression.

$\frac{4 - (- 3)}{- 7}$ $(4-(-3))/(-7)$

Simplify the numerator.

$\frac{7}{- 7}$ $7/(-7)$

Simplify.

$- \frac{7}{7} = - 1$ $-7/7=-1$

How do you evaluate s−rt(s-r)/t given r=-3, s=4, t=-7?
