Mathematics

Ivahew [28]3 years ago

Answer: D = -16

Step-by-step explanation: First you have to isolate the variable by subtracting the coefficient 8D from both equations then subtracting 1 from both equations to isolate 1D.

9d + 1 = 8d - 15

1d + 1 = -15

1d = -16

D = -16

hope this helped

Answer: The Answer To 9d + 1 = 8d -15

Step-by-step explanation:

STEP 1. Combine Like Terms As Well As Changing The Sign(s)

(WHEN YOU CHANGE SIDES YOU CHANGE THE SIGNS!!!)

<h3><em>9d + 1 = 8d - 15</em></h3><h3><u><em>-8d      -8d</em></u></h3><h3><em>d + 1 = -15</em></h3>

<em>STEP 2. Switch Signs Or Make It Opposite</em>

<em>d + 1 = - 15</em>

<h3> <u>   </u><u>-1     -1</u></h3><h2>d = -16</h2><h3></h3>

John bought 3 pencils for $0.75 each and a notebook for $4.25. If the tax rate is 5%, what is the total amount of John's purchas
SIZIF [17.4K]

Answer:

$6.83

Step-by-step explanation:

First calculate the before-tax total amount:

$0.75 + $0.75 + $0.75 + $4.25, or

3($0.75) + $4.25 = $2.25 + $4.25 = $6.50    (total before tax)

The before-tax total PLUS the 5% tax comes to:

$6.50 + 0.05($6.50) = $6.50 + $0.33  =  $6.83
