Lena and 3 of her friends bought just enough food to go on a 12- day camping trip. Pete and Jane surprised them by showing up at

bekas [8.4K]

The number of people increased by 2.

This means as a ratio it is now 6/4 as many as originally planned.

6/4 can be reduced to 3/2.

The time and the number of people are inversely proportional, so the food would last 2/3 ( inverse is flipping the original ratio over) the original length of time.

This means the length of time the food lasts is reduced by 1/3, which is 33.3%

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

$\: \: \: \: \: \:$

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

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>
