Question

each expression if $r = 12$, $s = - 4$, and $t = - 6$,

1. $rs + 16$
2. $\frac{t - r}{3}$

12 $\frac{8 - t}{- 2}$
distance remaining for a road trip over several hours is
wn in the table. use the information to find the constant
of change in miles per hour. (example 3)

justify conclusions last year, mr. engles total income was
$52,000$, while his total expenses were $53,800$. use the expression
$\frac{- e}{12}$, where $i$ represents total income and $e$ represents total expenses,
find the average difference between his income and expenses each
month. then explain its meaning. (example 7)

Explanation:

Step1: Substitute values

Substitute \(I = 52000\) and \(E = 53800\) into the expression \(\frac{I - E}{12}\).

$$ \frac{52000 - 53800}{12} $$

Step2: Calculate numerator

Calculate \(52000 - 53800=-1800\).

$$ \frac{- 1800}{12} $$

Step3: Divide

Divide \(-1800\) by \(12\).

$$ \frac{-1800}{12}=-150 $$

Answer:

The value of the expression is \(-150\). This means that, on average, Mr. Engle had a deficit of \(\$150\) each month (since his expenses were greater than his income).
