A number is increased by 54. The sumos then divided by 9. The result is 21. Write an equation to represent the discription, use

hram777 [196]

Answer:

(n+54)/9 = 21

Step-by-step explanation:

A number: n

Is increased by 54: n+54

The sum is divided by 9: (n +54)/9

and the result is 21:

The following table shows the cost for a person to go to the 4 - H Fair to go on a certain number of rides: Develop an equation

PtichkaEL [24]

In order to develop an equation, let's use the slope-intercept form of the linear equation:

$y=mx+b_{}$

Using the points (3, 13.5) and (5, 18.5) from the table, we have:

$\begin{gathered} (3,13.5)\colon \\ 13.5=3m+b \\ (5,18.5)\colon \\ 18.5=5m+b \end{gathered}$

Subtracting the second and the first equation:

$\begin{gathered} 5m+b-(3m+b)=18.5-13.5 \\ 2m=5 \\ m=2.5 \end{gathered}$

Now, finding the value of b:

$\begin{gathered} 13.5=3m+b \\ 13.5=7.5+b \\ b=13.5-7.5 \\ b=6 \end{gathered}$

So the equation that represents this table is y = 2.5x + 6

Looking at the options, the correct one is E (none of the above).
