Answer:

Rate of change is increase of 51 followers per year.

Step-by-step explanation:

Given:

Number of followers in 2012 = 74

Number of followers in 2015 = 227

Therefore, increase in followers = 227 - 74 = 153

Duration for the change = 2015 - 2012 = 3 years

Rate of change of followers is given as:

$\textrm{Rate of change}=\frac{Increase}{Duration}=\frac{153}{3}=51$

Therefore, rate of change is increase of 51 followers per year.

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{40}}}}}$

Step-by-step explanation:

$\sf{50 \: \% \: of \: 80}$

To convert the percent into a fraction , divide it by 190 and remove the % symbol. Then , Simplify the fraction to its lowest term.

⇒ $\sf{ \frac{50}{100} \times 80}$

⇒ $\sf{ \frac{1}{2} \times 80}$

Divide 80 by 2

⇒ $\sf{40}$

Hope I helped!

Solve the equation 3(x - 7) = 42

Effectus [21]

Answer:

x=21.

Step-by-step explanation:

First you distribute 3 to the parenthesis. You should get 3x-21=42 at this point. Then you add 21 to 42 to get 63. Here you should be at 3x=63. Divide 63 by 3 to get x=3
