Find the value of x in the solution to the system of equations shown.
A. x = 2.33
B. x = 3
C. x = 4.2
D. x = 5.4
Answers
y = 14x - 6
y = -4x + 48
14x - 6 = -4x + 48
add 6 to both sides
14x = -4x + 54
add 4x to both sides
18x = 54
divide both sides by 18
x = 3
The option is B.) x = 3

The value of x in the solution to the system of equations will be 3. Then the correct option is B.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The system of linear equations is given below.
y = 14x - 6 ...1
y = -4x + 48 ...2
From equations 1 and 2, then the value of the variable 'x' will be given as,
14x - 6 = -4x + 48
14x + 4x = 48 + 6
18x = 54
x = 3
The value of x in the solution to the system of equations will be 3. Then the correct option is B.

Proportionality constants are usually expressed as fractions, so lets convert 0.25 to a fraction. To do that we are going to add the denominator 1 to our decimal, and then we will multiply both numerator and denominator by ten for every number after the decimal point:
[tex] \frac{0.25}{1} [/tex]
[tex] \frac{0.25}{1} . \frac{100}{100} = \frac{75}{100} [/tex]
Finally, we can simplify our fraction:
[tex] \frac{25}{100} = \frac{1}{4} [/tex]
We can conclude that the constant of proportionality in text of the cost per text is 1/4

You had $50. You spent 10% of the money on clothes, 20% on games, and the rest on books. How much was spent inborn books?
Answers
Answer:
$35 was spent on books
Step-by-step explanation:
We must figure out the percent out of $50 that the books are worth
This is 70%
Now we need to figure out how much 10% is out of $50
50 divided by 10
10 percent of the books is 5 dollars
Now to find 20% we do 5+5=10 because it is just x2 of 10%
So we have spent 15 dollars on clothes and games
So now all we must do is 50-15=35
This is how we get our answer!
Pls mark me brainliest! Hope this helps :D
After spending 10% on clothes 20% on games I spent $35 on books.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, You had $50. You spent 10% of the money on clothes, 20% on games, and the rest on books.
Therefore, The expression that represents the context is,
$(50 - (10/100)×50 - (20/100)×50).
= $(50 - 5 - 10).
= $35.
SO, $35 she spent on books.

Kylie is on a swing the swing moves back and forth every 5 seconds. About how many minutes would it take Kylie to go back and forth one hundred times? Can you help me figure the minutes out in a fraction?
Answers
The fraction of the total time in minutes is therefore 8 1/3 minutes, which is equal to 25/3 minutes when expressed as an improper fraction.
To determine the amount of time it would take for Kylie to swing back and forth 100 times, we must first understand that the period of the swing, the time it takes to complete one full cycle back and forth, is 5 seconds. Therefore, we can calculate the total time for 100 swings by multiplying the period by the number of swings:
Total time (seconds) = Period (seconds per swing) * Number of swings
Total time (seconds) = 5 seconds/swing * 100 swings
Total time (seconds) = 500 seconds
To convert seconds into minutes, we divide by the number of seconds in a minute, which is 60:
Total time (minutes) = Total time (seconds) / 60 seconds/minute
Total time (minutes) = 500 seconds / 60 seconds/minute
Total time (minutes) = 50/6 or approximately 8 minutes and 20 seconds.
The fraction of the total time in minutes is therefore 8 1/3 minutes, which is equal to 25/3 minutes when expressed as an improper fraction.

Thus, radius of cylinder = [tex]\frac{10}{2}=5\ inches[/tex]
Let h be the height of the cylindrical container.
Then , The volume of the cylindrical container is given by :-
[tex]1256=\pi (5)^2h\\\\\Rightarrow\ h=\frac{1256}{5^2\pi}\\\\\Rightarrow\ h=\frac{1256}{25\times3.14}\\\\\Rightarrow\ h=16}[/tex]

So the answer is choice B
Another way to see this answer is to drop everything after the 6 (which is what is in the ten-thousands digit place) and replace all of those dropped digits with 0s. We add 1 to the digit we didn't get rid of because the 8 after the 6 is larger than 5
Your answer would be (68,00) because when rounding to the nearest 10th, we basically look at the tenth place.
6(8).
Number 8 is the 10th place, and it is over 5 to pass to line.

a 12 foot tall building casts on 8 foot long long shadow. how long of a shadow will a 5 foot tall women have
Answers
Using the concept of similar triangles and the given ratio of a building's height to its shadow, it was calculated that a 5-foot tall woman would cast a shadow that is approximately 3.33 feet long.
Explanation:The question deals with similar triangles where the ratio of the height of an object to the length of its shadow is constant if the sun's rays are considered to be parallel. Given that a 12-foot tall building casts an 8-foot long shadow, we can use this ratio to determine the length of the shadow that a 5-foot tall woman will cast.
First, find the ratio of the building's height to its shadow's length:
Height of the building / Length of shadow = 12 feet / 8 feet = 1.5Since the ratio should remain the same, we can set up a proportion for the woman:
Height of the woman / Length of her shadow = 5 feet / x (the unknown length of the shadow)Now solve for 'x' using cross multiplication:
12 / 8 = 5 / x12*x = 5*8x = (5*8) / 12x = 40 / 12x = 3.33 feet (approximately)Therefore, the shadow cast by the 5-foot tall woman will be approximately 3.33 feet long.
