Answer: 
Step-by-step explanation:
Since you did not indicate what you need to do, I assume that you have to write an expression using the sentence given in the problem.
In order to solve this exercise, it is importat to remember the following information:
1. The quotient is the result of a division.
2. The sum is the result of an addition.
3. The word "twice" indicates a multiplicatio by 2.
4. The word "cube" indicates an exponent 3.
Then, keeping on mind the explained above and the data given in the exercise, you know that:
-The sum of
and
can be expressed as:

- Twice the cube of
can be expressed in the following form:

Therefore, you can dermine that "the quotient of the sum of
and
and twice the cube of
" is represented with the following expression:

O
Answer:
The number is 75
Step-by-step explanation:
Let x be the unknown number
of means multiply and is means =
1/5 x = 15
Multiply each side by 5
5 * 1/5 x = 5*15
x = 75
Slope of EF = 5/2
Slope of XY=4/3
Further explanation:
"Slope is the steepness of a line"
The formula for slope when two lines are given:

Now,
<u>1. E(2-1) and F(4,4)</u>

<u>2. X(1, 4) and Y(-2,0)</u>

Hence,
Slope of EF = 5/2
Slope of XY=4/3

Answer: 0.6</h3>
Work Shown:
tan(angle) = opposite/adjacent
tan(30) = x/1
x = tan(30)
x = 0.57735 approximately
x = 0.6
--Answer--
1. $85
2. $15
--Explanation--
1. 15% off of 100 just means moving the decimal in 15 over by 2 to the left.
From there, multiply 100 x 0.15.
Then you get 15, so that's how much tax you are paying. Meaning Subtract 15 from 100 to get the price it originally was before tax. 100 - 15 = 85.
2. $15 dollars tax from moving decimal 2 to the left of 15%.
