Find the unit rate for each

$8.31/3 pounds= $2.77 per pound

$12.95/5 pounds= $2.59 per pound

Final answer: The second option is better because you are paying less per pound (2.59<2.77).

We can find the answer by dividing each price by the amount of pounds and then seeing which number is bigger. Lets try...

8.31/3=2.77

12.95/5=2.59

Since the 12.95 deal allows you to get one pound for just 2.59, that is the better deal.

Hope this helps!

The sum of two numbers is twice their difference. the larger number is 6 more than twice the smaller. find the numbers.

soldi70 [24.7K]

Let the numbers be x and y; x being the larger number and y being the smaller.

Given,

x + y = 2* (x - y)

x + y = 2x - 2y

x = 3y

Also given,

x = 6 + 2y

3y = 6 + 2y

--- y = 6

Thus, x = 3y = 3*6 = 18.

Therefore, the numbers are 18 and 6.

Adding fractions 1/6+2/3=

mars1129 [50]

Answer:

$\frac{5}{6}$

$\frac{1}{6} + \frac{2}{3}$ is equivalent to $\frac{1}{6} + \frac{4}{6}$ .

This is because $\frac{2}{3}=\frac{4}{6}$

The rule is, in order to add fractions, your denominators must be equivalent. In other words, you must have the same denominator for both fractions.

$\frac{1}{6} + \frac{4}{6} =\frac{5}{6}$

This is because 4 + 1 = 5.

Your answer is $\frac{5}{6}$ .

I hope this helps!

In the diagram shown, AE 1/3AC and ED ll CB. Explain why df must be one-fourth length of CD

Blizzard [7]

The value of the length DF is 1/4 of that of CD because of the Angle Bisector Theorem for triangles.

<h3>What is the Angle Bisector Theorem?</h3>

The Angel Bisector Theorem states that if a ray bisects an angle of a triangle, it dissects the side of the triangle that is opposite to the dissected angle into parts that are proportionate to the adjacent sides.

Note that the angle that has been dissected here is ∠CBD. Thus,

$\frac{DF}{CF}$ = $\frac{BD}{BC}$
