Answer:

16.2p (If lemonade is .75p, if not substitute in the equation below)

Step-by-step explanation:

In 4 liters, there would be 3 liters of lemonade and 1 liter in juice.

I am assuming 75p is meant to be .75p

So 4 liters costs: (1 x 1.8) + (3 x .75) = 4.05

We need 16 so: 4.05 x 4 = 16.2

Marty read 4 times as many pages as Nelson and Jennifer COMBINED. Marty read 1,860 pages.

In total, after dividing Marty's total by 4, Jennifer and Nelson both read a total of 465 pages.

After subtracting Nelson's 240, Jennifer is then found to have read 225 pages.

B would be the best viable option, as it clearly shows that 240+?x4=1,860, which it does.

Hope this helped. Khan Academy is a great resource for any learner. :)

1. Howard's CD House sells new CDs for $15 each and used CDs for $6 each. Bre'anna bought 51 CDs and spent a

Yanka [14]

The numbers of new CDs is 30 and the old CDs is 21.

To solve this problem, we have to write a system of equations in which we would know the numbers of each types of CD she bought.

<h3>System of Equations</h3>

This is used to solve a series or complex of word problems in which we can represent in a mathematical statements;

Let n represents numbers of new CDs
Let u represents numbers of old CDs

The equations can be represented as

$n + u = 51 ...equation(i)\\15n + 6u = 576 ... equation(ii)$

Let's take equation (i)

Making n the subject of formula

$n + u = 51\\n = 51 - u...equation(iii)$

we can put equation (iii) into equation (ii)

$15n + 6u =576\\n = 51 - u\\15(51 - u) + 6u = 576\\765-15u + 6u = 576\\collect like terms\\765-576=15u - 6u\\189=9u\\9u/9 = 189/9\\u = 21$

Let's put the value of u into equation (i)

$n + u = 51\\u = 21\\n + 21 = 51\\n = 51 - 21\\n = 30$

From the calculations above, the numbers of new CDs is 30 and the old CDs is 21.

Find the area of a regular polygon with 7 sides that has a side length of 6 inches and an apothem of 8 inches

alukav5142 [94]

We can always split a regular polygon with $n$ sides into $n$ triangles, whose base is the side of the polygon and whose height is the apothem of the polygon. So, the sum of the areas of all these triangles is

$A=n\times \dfrac{s\cdot a}{2}$

where $n$ is the number of sides, $s$ is the side length, and $a$ is the apothem length.

So, you just need to plug you values in: in your case, you have $n=7,\ s=6,\ a=8$

So, the formula becomes

$A=7\times \dfrac{6\cdot 8}{2} = 7 \times 6\cdot 4 = 168$

Anarel [89]

Answer:

250 Students are musicians, 200 are not.

Step-by-step explanation:

Decimal Version:

If we take "5 out of every nine students are musicians" and make this a fraction we get 5/9. 5/9 as a decimal is approximately 55.555555555556. 55.555555555556% of 450 = 250. So that means 250 students are musicians.
