Answer: 24%

Step-by-step explanation:

Since we are informed that the Girl Scout Troop started with 25 girls and at the end of the year party there were 31 girls. The percentage change will be:

= (31 - 25) / 25 × 100

= 6/25 × 100

= 24%

The error that Gabby made was that she used 31 as the base. This is expressed below:

= 31 - 25) / 31 × 100

= 6/31 × 100

= 19.4%

Simplify this equation<br> -5x+7&gt;22
Lana71 [14]

Answer:

<h2>x < - 3</h2>

Step-by-step explanation:

- 5x + 7 > 22

Move 7 to the other side of the inequality

- 5x > 22 - 7 \\  - 5x > 15

Divide both sides by - 5

\frac{ - 5x}{5}  >  -  \frac{15}{5}  \\ x >  - 3

Reverse the sign

We have the final answer as

<h3>x < - 3</h3>

Hope this helps you
