Since each smallboxes can hold 9 CDs
Then to find how many boxes you need for 54 CDs, you have to divide 54 by 9 which gives 6.

Answer: 6 smallboxes are needed

The focus of a parabola is (−5,−1) and the directrix is y=−3. What is an equation of the parabola? (x+5)2=8(y+5)

There are two approaches to solving the equation -3x + 10 = 4x - 20
pashok25 [27]

Answer:

X =30/7

Step-by-step explanation:

The first way would be something like:

-7x + 10 = -20. The first thing we would do is to subtract 10 from both sides.

Therefore,

-7x+10-10=-20-10

Simplified, we get

-7x=-30

Remove the negative symbols

7x =30

x=30/7

Second example:

10=7x - 20

Add 20 to both sides.

10+20=7x-20+20

Simplified,

30=7x

x = 30/7

L'Shonda purchased a container of juice
cupoosta [38]

L'Shonda purchased a container of juice. 80 calories are from carbohydrates.

<u>Solution:</u>

Given that, LShonda purchased a container of juice that contains 200 calories.  

The label says that 40% of the calories are from carbohydrates.  

We have to find how many calories are from carbohydrates?

Now, according to the given information,

<em>Number of calories from carbohydrates = 40% of the total calories of the juice </em>

Then, calories from carbohydrates = 40% of 200 calories

40% can be written in fraction as \frac{40}{100}

\text { Calories from carbohydrates }=\frac{40}{100} \times 200=40 \times 2=80 \text { calories }

Hence, 80 calories are from carbohydrates.
