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).

The ratio of the number of boys to the number of girls in a theater is 7:9. There are 12 more girls than boys. How many children

skelet666 [1.2K]

Ok, there is an equation you can use to solve it.

n is a number.

p is also a number, but different to n.

$\frac { 7 }{ 9 } \cdot \frac { n }{ n } =\frac { p }{ p+12 } \\ \\ \frac { 7 }{ 9 } \cdot 1=\frac { p }{ p+12 } \\ \\ \frac { 7 }{ 9 } =\frac { p }{ p+12 }$

$\\ \\ 7\left( p+12 \right) =9p\\ \\ 7p+84=9p\\ \\ 9p-7p=84\\ \\ 2p=84\\ \\ p=\frac { 84 }{ 2 } \\ \\ p=42$

Therefore:

<u></u> $\frac { 7 }{ 9 } \cdot \frac { n }{ n } =\frac { 42 }{ 42+12 } =\frac { 42 }{ 54 } =\frac { 7 }{ 9 } \cdot \frac { 6 }{ 6 } \\ \\ \therefore \quad n=6$

So all together there were 54 girls and 42 boys in the theatre.

54 + 42 = 96

That's 96 children in total. (Answer)

7:9 = 42:54
