Answer:

d = -16

Step-by-step explanation:

Step 1: Write equation

89 = -5d + 9

Step 2: Solve for <em>d</em>

<u>Subtract 9 on both sides:</u> 80 = -5d

<u>Divide both sides by -5:</u> -16 = d

Step 3: Check

<em>Plug in x to verify if it's a solution.</em>

89 = -5(-16) + 9

89 = 80 + 9

89 = 89

Dragon drop each expression two correctly classify it as having a positive or negative product
ioda

Step-by-step explanation:

We multiply it to find the product

positive times positive = positive

positive times negative = negative

negative times positive = negative

negative times negative = positive

(-\frac{1}{3})(-\frac{1}{3})= \frac{1}{9}

Negative and negative is positive , so product is positive

(-\frac{1}{3})(\frac{1}{3})= -\frac{1}{9}

Negative and positive is negative , so product is negative

(\frac{1}{3})(-\frac{1}{3})= -\frac{1}{9}

positive and negative is negative , so product is negative

(\frac{1}{3})(\frac{1}{3})= \frac{1}{9}

positive and positive is positive , so product is positive
