If f(x)=6x-15 and f(a)=30, what is the value of a?<br> Please help

mariarad [96]

Answer:

$a=7.5$

Step-by-step explanation:

Given the function $f(x)=6x-15$ and the output $30$ when $x=a$ , we can write the equation:

$6a-15=30$

$6a=45$

$a=7.5$

We can insert the value of $a$ into the function to verify the output equals $30$ :

$f(a) = 6a-15$

$= 6(7.5)-15$

$=30$

∴ We have verified that $a=7.5$

Hope this helps :)

<h2>Number of boards required is 24</h2>

Step-by-step explanation:

A builder is building a fence with 6 and 1/4 inch wide wooden boards arranged side-by-side with no gaps.

$\texttt{Length of 1 board = }6\frac{1}{4}in\\\\\texttt{Length of 1 board = }\frac{6\times 4+1}{4}=\frac{25}{4}in$

We need to build a fence that is 150 in long.

Length of fence = Number of boards required x Length of 1 board

$150=\texttt{Number of boards required }\times \frac{25}{4}\\\\\texttt{Number of boards required }=\frac{150\times 4}{25}\\\\\texttt{Number of boards required }=6\times 4=24$

Number of boards required = 24
