To find the relation between them, you need transform them to the same currency. Let's transform them to cents.
$3.60 = 360 cents.
One quarter is 25 cents, and one nickel is 5 cents.

So 360 = 25q + 5n

Hope this helps! :D

$Hello!~$

$Let's~answer~your~question!$

$So,~for~this~equation,~we~need~to~use$ $~the~distributive~property~of$ $~multiplication.~but,before~we~start~to~solve$ $this~equation,~let's~get~to~know~what$

$distributive ~property ~of~multiplication~means!$

<em><u /></em>

<em><u>Distributive property of multiplication :</u></em>

$Distributive~property~of~multiplication~states~that$ $when~a~~number~is~multiplied$

$by~the ~sum ~of~ two~ numbers,$ $the~ first~ number ~can~ be ~distributed ~to$ $both ~of~those$ $numbers~and~multiplied~by~each~of~them$ $separately.$

→ $a*(b+c)=a*b*+~a*c$

<em><u>Now, that we know what it means let's apply it in our equation:</u></em>

<em><u /></em> $(2*x)+(2*7)=36$ <em><u /></em>

<em><u /></em>

<em><u>Now, we simplify:</u></em>

<em><u /></em> $2x+14=36$ <em><u /></em>

<em><u /></em>

<em><u>Divide both sides by 2 in the equation:</u></em>

<em><u /></em> $\frac{2x+14}{2} =\frac{36}{2}$ <em><u /></em>

<em><u /></em>

<em><u>Simplify :</u></em>

<em><u /></em> $x+7=18$ <em><u /></em>

<em><u /></em>

<em><u>Thus, the first correct step is option B,</u></em>

<em><u /></em> $then~comes,~option~"A"~then,~option~"F"~as~shown~above$ $The~remaining~options~are~not~enough~information~to~solve~the~given$ $equation:(x + 7) = 36.$

Find an expression for the function whose graph is the line segment joining the points (1, -1) and (5, 5). (Assume that these po

bagirrra123 [75]

Namely, what's the equation of a line that passes through (1,-1) and (5,5)

well, first off let's find its slope, and the plug all those values in the point-slope form.

$\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({{ 1}}\quad ,&{{ -1}})\quad 
% (c,d)
&({{ 5}}\quad ,&{{ 5}})
\end{array}
\\\\\\
% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{5-(-1)}{5-1}\implies \cfrac{5+1}{5-1}
\\\\\\
\cfrac{6}{4}\implies \cfrac{3}{2}$

$\bf \stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies y-(-1)=\cfrac{3}{2}(x-1)
\\\\\\
y+1=\cfrac{3}{2}x-\cfrac{3}{2}\implies y=\cfrac{3}{2}x-\cfrac{3}{2}-1\implies y=\cfrac{3}{2}x-\cfrac{5}{2}$
