Amanda and Ndiba are selling flower bulbs for a school fundraiser. Customers can buy packages of tulip bulbs and bags of daffodi
Mumz [18]

Answer:

daffodil = $13 Tulip = $7

Step-by-step explanation:

6t + 12d = 198

7t + 6d = 127

6t = 198 - 12d

t = 33 -2d

substitute

7(33-2d) + 6d = 127

231 -14d +6d = 127

- 8d = -104

d =13

6t + 12(13) = 198

6t +156 = 198

6t = 42

t = 7

7+4(r+3)=9r-6<br> show work pls AND HELP ASAP
ivanzaharov [21]

\:  \:  \:  \:  \:  \:

=  \:  \:  \:  \: r = 5

Step-by-step explanation:

7 + 4(r + 3) = 9r - 6

  • <em><u>distribute</u></em><em><u> </u></em>4 through the parentheses

7 + 4r + 12 = 9r - 6

  • add numbers

19 + 4r = 9r - 6

  • move the <em><u>variable</u></em><u> </u>to the left hand side and change its sign

19 + 9r =  - 6

  • move the <em><u>constant </u></em>to the right hand side and change its sign

4r - 9 =  - 6 - 19

  • collect<em><u> like</u></em><em><u> terms</u></em>

<em><u>- 5r =  - 6 - 19</u></em>

  • calculate the difference

- 5r =  - 25

  • divide both sides of the equation by <em>-</em><em>5</em>

<em>=  \:  \:  \:  \: r = 5</em>

<h2><em><u>hope</u></em><em><u> it</u></em><em><u> helps</u></em></h2>
