First, do distributive property. 3 • x and 3 • -4. Now you get 3x-12=12. Now add 12 to both sides. Now you have 3x=24. Now divide by 3 to get your x alone and you answer which is 8!

Elena-2011 [213]

Answer:

The percentage decrease in the number candid student pictures for the yearbook from 2015 to 2016 is approximately 9.3 percent

Step-by-step explanation:

The given data can be presented as follows

Year ${}$ Number of Photos

2015 ${}$ 236

2016 ${}$ 214

The percentage decrease in the number of candid pictures is give by the following formula

$Percentage \ Decrease = \dfrac{Original \ Value- New \ Value}{Original \ Value} \times 100$

Where;

Original value for the number of pictures = 236

New value for the number of pictures = 214

Substituting the values into the equation for the percentage decrease gives;

$Percentage \ Decrease = \dfrac{236- 214}{236} \times 100 = \dfrac{550}{59} \ percent\approx 9.3 \%$

The percentage decrease is approximately 9.3 percent.
