25 pts and a mark for real answers. Help!! A store is having a sale on chocolate chips and walnuts. For 5 pounds of chocolate ch

kozerog [31]

Answer:

Each pound of chocolate chips costs $ 1.5 and each pound of walnuts cost $ 3.75 .

Step-by-step explanation:

Let, each pound of chocolate chips costs $ x and each pound of walnuts costs $ y.

Then, according to the question,

5x + 6y = 30 --------------(1) and,

3x + 2y = 12 ----------------(2)

Multiplying (2) by 3 we get,

9x + 6y = 36 ---------------------(3)

Deducting (1) from (3) we get,

4x = 6

⇒ x = 1.5 ----------------------(4)

From (4), putting the value of x in (2) , we get,

2y = 7.5

⇒ y = 3.75 ---------------------------(5)

$\huge\text{Hey there!}$

$\huge\textbf{What does \boxed{median} mean in math?}}$

$\boxed{\text{Median}}\rightarrow\textsf{ is the number in the middle.}$

$\huge\textbf{How do you find the \boxed{median}?}$

$\text{You can found it by putting the numbers from \bf least to greatest.}$

$\huge\textbf{Question reads....}$

$\text{Find the median for the scores 91, 69, 71, 82, 71, 95, 87, 74, 71, 89, 89, 95,}\\\text{72, 75}$

$\huge\textbf{Equation:}$

$\text{91, 69, 71, 82, 71, 95, 87, 74, 71, 89, 89, 95, 72, 75}$

$\huge\textbf{Rearrange the problems to:}$

$\text{69,71,71,71,72,74,75,82,87, 89,89,91,95,95}$

$\huge\textbf{The expression:}$

$\mathsf{\dfrac{75 + 82}{2} = median}$

$\huge\textbf{Simplify it:}$

$\mathsf{\dfrac{75 + 82}{2} = median}$

$\mathsf{\dfrac{157}{2} = median}$

$\mathsf{257\div2 = median}$

$\mathsf{78.5 = median}$

$\huge\textbf{Therefore, your answer should be:}$

$\huge\boxed{\mathsf{78.5}}\huge\checkmark$

$\huge\text{Good luck on your assignment \& enjoy your day!}$
