-3 (3x-5)=87

-9x + 15 = 87

<em>Answer,</em>

<em>X = -</em><em>8</em>


<em>Explanation,</em>

<em><u>Step 1: Simplify both sides of the equation.</u></em>

<em>−3(3x − 5) = 87 </em>

<em>(−3)(3x) + (−3)(−5) = 87 (Distribute)</em>

<em>−9x + 15 = 87</em>

<em><u>Step 2: Subtract </u></em><em><u>15</u></em><em><u> from both sides. </u></em>

<em>−9x + 15 − 15 = 87 − 15 </em>

<em>−9x = 72</em>

<em><u>Step 3: Divide both sides by </u></em><em><u>-9</u></em><em><u>.</u></em>

<em>-9x/-9 = 72/-9</em>

<em>X = </em><em>-8</em>


<u><em>Hope This Helps :-)</em></u>

A shoe store buys a pair of boots from a supplier for $45. The store's manager decides on a markup of 35%. What is the new price
Gnom [1K]

Answer:

The new price of the books = $60.75

Step-by-step explanation:

  • As the original price is: $45

As the markup is: 35% = 35/100 = 0.35

The Markup on the original price is:

0.35 × 45 = $15.75

Hence, the new price of the boots:

$45 + $15.75 = $60.75

Therefore, the new price of the books = $60.75
