Answer:
y=25/6
Step-by-step explanation:
We can set up a proportion!
We know that y/x=y/x because they vary directly.
So, we have 5/6=y/5. We need to solve for y.
We cross multiply and get:
6y=25
y=25/6
When x equals 5, y will equal 25/6.

A company sells two versions of an antivirus software. The home edition costs $23.50, and the business edition costs $58.75. Last week, the company earned $29,668.75 from selling 745 copies of the software.
If x represents the number of copies of the home edition sold and y represents the number of copies of the business edition sold, which system of equations represents this situation?
Answer:
x + y = 745
23.50x + 58.75y = 29,668.75
Step-by-step explanation:
Since 745 copies were sold and x represents the number of copies of the home edition sold and y represents the number of copies of the business edition sold:
x + y = 745
Since the home edition costs $23.50, and the business edition costs $58.75:
The money earned from home edition is = 23.50x
The money earned from business edition is = 58.75y
Since the company earned $29,668.75:
23.50x + 58.75y = 29,668.75

Find the value of x in the given
right triangle.
10
37°
Х
x = [?]
Enter your answer as a decimal rounded to the
nearest tenth.
Enter
Answer:
x ≈ 8.0
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos37° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{x}{10}[/tex] ( multiply both sides by 10 )
10 × cos37° = x , thus
x ≈ 8.0 ( to the nearest tenth )
The value of the x is 8 units after applying the cos ratio, which is the ratio of the side adjacent to angle to hypotenuse.
What is a right-angle triangle?
It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.
We have a right angle triangle shown in the picture.
As we know, the cos is the ratio of the side adjacent to angle to hypotenuse.
cos37 = x/10
x = 10cos37
x = 10(0.79)
x = 7.9 ≈ 8 units
Thus, the value of the x is 8 units after applying the cos ratio, which is the ratio of the side adjacent to angle to hypotenuse.

Explain how you determine each of the two expressions of the equation when the mathematical statement is given in words. Explain how you determine each of the two expressions of the equation when the mathematical statement is given in words.
Answer: This can be done by properly interpreting the words into appropriate signs and digits.
Please check below for explanation of WORD PROBLEMS.
Step-by-step explanation: In mathematics, as you move to a higher level, you would encounter more of word problems than simply figures and signs. This simply means, you would be presented with series of statements that should be interpreted and hence an equation would be derived and then solution proffered. First it is really important to note that an equation only exists when the expression on one side is equal to that on the other side. Equally important are the following expressions;
(1) Sum refers to addition (plus)
(2) Difference refers to subtraction (minus)
(3) Product refers to multiplication (times) and
(4) Quotient refers to division (divide)
(5) The same as refers to equal to
Hence, interpreting the expression is largely determined by the use of any of the above expressions and the slightest error in interpreting negates everything afterwards.
So on the one hand, one set of statements will usually tell you that, "so and so is the same as" this and that. This is interpreted as "so and so" is equal to "this and that."
A simple example would help to illustrate this;
Illustration:
(a) Four times a number added to a dozen would result in seven times that same number.
Solution; Let the number be x. Four times a number means 4 times x, which gives you 4x.
Added to a dozen means you add 4x to a dozen, that is 4x + 12.
This would result in seven times that same number. Simply put, what you just did above (4x + 12) would result in or would be equal to 7 times x which is 7x. This now gives you,
4x + 12 = 7x.
Therefore to determine each of the two expressions of an equation is largely dependent on properly interpreting the words into the appropriate signs and figures (that is, plus, minus, times, divide and equal to).

Everything to the left of the circle is shaded. A number line going from 95 to 103. A closed circle is at 98.6. Everything to the left of the circle is shaded.
Answer:
The correct option is;
A. A number line that goes from 95 to 103. A closed circle is at 98.6. Everything to the right is shaded.
Step-by-step explanation:
To represent x greater-than-or-equal-to 98.6 on the number line we note that an open circle stands for either a less than or a greater than, while an open circle stands for either less than or equal to or greater than or equal to
The correct way to represent x greater than or equal to 98.6 on the number line, we indicate the point 98.6 with a closed circle and we shade everything in the region of the solution which is to the right of the closed circle
Therefore the correct option is A. A number line that goes from 95 to 103. A closed circle at is at 98.6. Everyting to the right is shaded.

Please! Can someone help me with this task I do not understand?
Answer:
Given
Hope this helps
Step-by-step explanation:
The task explains how to draw a circle. So first attach a thumbtack in between the paper. This will be the midpoint of the circle
Tie one end of thread to it and the other end to a pencil. So when you travel the pencil around, a circle will be formed.
The length from one end of the circle to the other end (which pases the centre) is the diameter. Half of that is the radius
Circumference is the length around the circle which is πd
An easier way to draw the circle is by simply using a compass instead.
Your friend has $100 when he goes to the fair he spends 10 to interfere in 20 on food Rides at the fair cost two dollars per ride which function can be used to determine how much money he has left over after x rides
Answer:
$70-$2x
Step-by-step explanation:
In the beginning, your friend spent $30 on interference and food, leaving him or her $70.
Since every ride costs $2, you multiply the amount of rides he rode by 2 to get how much he spent.
He subtracted that from the money he had which was $70.
Therefore, the equation is $70 - $2x

Erik and Nita are playing a numers game. If the difference of their two numbers is less than 10 then Erik wins. If the differece between their two numbers is greater than 10 then Nita wins. The numbers to choose from are zero to twenty. What is the range of numbers that will win the game for your player? (Erik) If your player is Erik, assume that Nita chooses 7. Remember that Erik and Nita can only use numbers from zero to twenty)
Answer:
The range of numbers that will win the game for your player is [tex]0 \leq x \leq 16[/tex].
Step-by-step explanation:
We are given that Erik and Nita are playing a numbers game. If the difference between their two numbers is less than 10 then Erik wins. If the difference between their two numbers is greater than 10 then Nita wins.
The numbers to choose from are zero to twenty.
Our player's name is Erik and we have to find the range of numbers that will win the game for Erik.
Given that Nita chooses 7.
Since we know that if the difference between the numbers chosen by Erik and Nita is less than 10 then Erik wins, so the inequality represented taking into account that Nita chooses 7 is given by;
[tex]|x-7|<10[/tex] , where x = number chosen by Erik, i.e. [tex]0 \leq x\leq 20[/tex]
Further solving the above equation we get;
[tex]-10 < x-7<10[/tex]
[tex]-10+7 < x-7+7 < 10 + 7[/tex]
[tex]-3 < x < 17[/tex]
But keeping in mind the fact that Erik and Nita can choose numbers between 0 and 20 (inclusive) only.
SO, the required range of numbers that can win Erik the game is given by = [tex]0 \leq x \leq 16[/tex].

(17,0) and (-2,19)
Step-by-step explanation:
First, find the gradient of AB, which is 1. As CD is perpendicular, its gradient will be -1. The equation of CD will be y=17-x. The x intercept is where y=0. So, that will give you x=17. When x=-2, y=19. It proves the equation right.
