Answer:

d = -16

Step-by-step explanation:

Step 1: Write equation

89 = -5d + 9

Step 2: Solve for d

Subtract 9 on both sides: 80 = -5d

Divide both sides by -5: -16 = d

Step 3: Check

Plug in x to verify if it's a solution.

89 = -5(-16) + 9

89 = 80 + 9

89 = 89

How to turn negative mixed fraction into decimal

andre [41]

First off, if it's mixed, you'd want to convert it to "improper" first, and then do the division... say hmm - 3 and 1/7

$\bf \stackrel{mixed}{-3\frac{1}{7}}\implies -\cfrac{3\cdot 7+1}{7}\implies \stackrel{improper}
{-\cfrac{22}{7}}\implies -22\div 7\implies -3.\overline{142857}$

the line over the decimal part is because is a "recurrent decimal", or repeating one.
