Solve for ddd.

41 =12d-741=12d−741, equals, 12, d, minus, 7

d =d=d, equals  

Hint #11 / 4

Let's add and then divide to get ddd by itself.

Hint #22 / 4

\begin{aligned} 41 &=12d-7 \\ \\ 41\blue{+7} &= 12d-7\blue{+7}~~~~~~\blue{\text{add }7} \text{ to each side}\\ \\ 41\blue{+7}&=12d-\cancel{ 7} {\blue{+}\cancel{\blue{7}}}\\ \\ 41\blue{+7}&=12d\end{aligned}

=12d−7+7      add 7 to each side

=12d−

=12d

​  

Hint #33 / 4

\begin{aligned}48 &= 12d \\ \\ \dfrac{48}{\pink{12}} &= \dfrac{12d}{\pink{12}} ~~~~~~~\text{divide each side by } \pink{12} \text{ to get } d \text{ by itself }\\ \\ \dfrac{48}{\pink{12}}&=\dfrac{\cancel{12}d}{\cancel{\pink{12}}} \\ \\ \dfrac{48}{\pink{12}}&=d \end{aligned}

Hint #44 / 4

The answer:

\begin{aligned} 41 &=12d-7 \\\\ 41 &\stackrel{?}{=} 12(\green{4})-7 \\\\ 41 &\stackrel{?}{=} 48-7 \\\\ 41 &= 41 ~~~~~~~~~~\text{Yes!} \end{aligned}

Phil had 93 dollars, and his sister owed 10 dollars to her friend. How much should Phil give to his sister for each of them to h
slavikrds [6]

Answer:

$51.50

Step-by-step explanation:

<em>Let the amount that Phil give to her sister be  x</em>

<em><u>After Phil's sister pays her debt of 10, Phil and her sister should have EQUAL amount. </u></em>So we can write the equation as:

93-x=x-10

Now solving this for x, we have:

93-x=x-10\\93+10=x+x\\103=2x\\x=\frac{103}{2}=51.5

Hence, Phil must give $51.50 to her sister.
