wariber [46]

What's up? this answer is B, 72

we can figure out that one third of melissa's age is 24 because 18+6= 24. simply eliminate the obvious incorrect answers, A and C. 78/3= 26 so it isn't D
72/3=24 it is B

best of luck with your studies

Walnuts peanuts and chocolate chips are mixed in a ratio of 7:2:5. What is the weight of the mixture if 2.5lbs of chocolate chip

andreyandreev [35.5K]

In plain and short, we simply will divide the whole amount of 2.5lbs by (7+2+5), and then distribute accordingly to each component,

$\bf \stackrel{walnuts}{7}~~:~~\stackrel{peanuts}{2}~~:~~\stackrel{chocolate}{5}
\\\\\\
\stackrel{walnuts}{7\cdot \frac{2.5}{7+2+5}}~~:~~\stackrel{peanuts}{2\cdot \frac{2.5}{7+2+5}}~~:~~\stackrel{chocolate}{5\cdot \frac{2.5}{7+2+5}}$

$\bf \stackrel{walnuts}{7\cdot \frac{2.5}{14}}~~:~~\stackrel{peanuts}{2\cdot \frac{2.5}{14}}~~:~~\stackrel{chocolate}{5\cdot \frac{2.5}{14}}
\\\\\\
\stackrel{walnuts}{\frac{2.5}{2}}~~:~~\stackrel{peanuts}{\frac{2.5}{7}}~~:~~\stackrel{chocolate}{\frac{12.5}{14}}
\\\\\\
\stackrel{walnuts}{\frac{5}{4}}~~:~~\stackrel{peanuts}{\frac{5}{14}}~~:~~\stackrel{chocolate}{\frac{25}{28}}$

The coordinates of the top of a tree are (-3,8), and an acorn is attached to the tree at (-1,5). If we know that the acorn lies

Charra [1.4K]

Let's say that the coordinates of the squirrel are: (x, y)

Since the coordinates of the acorn is halfway, between the tree and the squirrel, that means the acorn is the midpoint.

To work out the midpoint you do:

(sum of x-coordinates) divided by 2, (sum of y coordinates) divided by 2.

We can use this to form an equation .

So the sum of the x coordinates of the tree and the squirrel = -1 :

x-coordinates of the squirrel:
