To complete the inequality, we convert the fractions to decimal form or find a common denominator to compare them. The number that completes the inequality is three-fourths (0.75), as it is larger than two-thirds but smaller than seven-ninths.
Explanation:
The student is asking which number fulfills the inequality between two-thirds and various other fractions. To determine the correct number that completes the inequality, we should consider the values of the fractions in decimal form or by comparing them to each other after finding a common denominator.
For example, two-thirds is approximately 0.666..., three-fifths is 0.6, seven-ninths is approximately 0.777..., three-fourths is 0.75, and six over nine is equivalent to two-thirds (as six-ninth simplifies to two-thirds).
Considering these values, the number that fills the gap should be bigger than two-thirds and smaller than the smallest fraction among the given options that is bigger than two-thirds. Therefore, three-fourths (0.75) fits the inequality because it is larger than two-thirds (approximately 0.666...) but less than seven-ninths (approximately 0.777...).
Which ordered pair in the form(x,y) is a solution of this equation?
7x-5y=1
A] (-3,-2)
B] (-2,-3)
C] (0,4)
D] (4,0)
The ordered pair is (-2, -3)
Step-by-step explanation:
Step 1: To find whether an ordered pair is a solution, substitute values of x and y and see whether it satisfies the equation.(-3, -2) ⇒ 7 × -3 - 5 × -2 = -21 + 10 = -11 ≠ 1
(-2, -3) ⇒ 7 × -2 - 5 × -3 = -14 + 15 = 1
(0, 4) ⇒ 0 - 5 × 4 = 20 ≠ 1
(4, 0) ⇒ 7 × 4 - 0 = 28 ≠ 1
So the ordered pair is (-2, -3)
The ordered pair that is a solution to the equation 7x-5y=1 is option B, (-2,-3), as it is the only pair that satisfies the equation when the values are substituted.
Explanation:The question asks which ordered pair is a solution to the equation 7x-5y=1. To find the solution, we simply substitute the x and y values from each ordered pair into the equation and see which pair satisfies the equation.
For option A (-3,-2), let's plug it in: 7(-3) - 5(-2) = -21 + 10 = -11, which does not equal 1.For option B (-2,-3), we get: 7(-2) - 5(-3) = -14 + 15 = 1, which does equal 1. Therefore, this is the correct solution.For option C (0,4), we get: 7(0) - 5(4) = -20, which does not equal 1.Lastly, for option D (4,0), plugging it in gives us: 7(4) - 5(0) = 28, which does not equal 1.So, the ordered pair that is a solution to the equation is option B, (-2,-3).

The axis of symmetry for the graph of the function f start bracket x end bracket equals one-quarter x square plus b x plus 10 is x=6. What is the value of b?
The value of b is -3
Explanation:
The function is [tex]f(x)=\frac{1}{4} x^{2} +bx+10[/tex] and [tex]x=6[/tex]
The function is of the form [tex]y=a x^{2}+bx+c[/tex]
where [tex]a=\frac{1}{4}[/tex], [tex]b=b[/tex] and [tex]c=10[/tex]
Using the axis of symmetry formula, we can determine the value of b.
Thus, the axis of symmetry formula is given by,
[tex]x=\frac{-b}{2a}[/tex]
Substituting the values, we have,
[tex]6=-\frac{b}{2(\frac{1}{4}) }[/tex]
Multiplying the denominator, we get,
[tex]6=-\frac{b}{\frac{1}{2} }[/tex]
Dividing, we get,
[tex]6=-2b[/tex]
Dividing both sides by -2, we get,
[tex]-3=b[/tex]
Hence, the value of b is -3.

In a year group of 60 pupils, 3/4 like Coke, 1/5 like Sprite and 3/10 like Tango. How many children like each drink? PLZ HELP ME ASAP 15 points to correct answer
Final answer:
To find out how many children like each drink in a year group of 60 pupils, calculate each fraction of the total. 45 pupils like Coke, 12 pupils like Sprite, and 18 pupils like Tango.
Explanation:
In a year group of 60 pupils, to find out how many children like each drink, you need to calculate the fractions of the total number of pupils.
To find out how many like Coke, multiply 3/4 by the total number of pupils: 3/4 × 60 pupils = 45 pupils.For Sprite, multiply 1/5 by the total number of pupils: 1/5 × 60 pupils = 12 pupils.For Tango, multiply 3/10 by the total number of pupils: 3/10 × 60 pupils = 18 pupils.Therefore, 45 pupils like Coke, 12 pupils like Sprite, and 18 pupils like Tango.
Final answer:
45 children like Coke, 12 children like Sprite, and 18 children like Tango.
Explanation:
To find out how many children like each drink, we can use the given fractions and the total number of children in the year group.
Let's calculate the number of children who like Coke:
Total children in the year group = 60
Fraction who like Coke = 3/4
Number of children who like Coke = (3/4) x 60 = 45
Similarly, we can calculate the number of children who like Sprite and Tango:
Fraction who like Sprite = 1/5
Number of children who like Sprite = (1/5) x 60 = 12
Fraction who like Tango = 3/10
Number of children who like Tango = (3/10) x 60 = 18
Therefore, 45 children like Coke, 12 children like Sprite, and 18 children like Tango.

What is the equation in standard form for (0,3) and (7,0)
Answer:
3x + 7y = 21
Step-by-step explanation:
We have value of two points (0,3) and (7,0)
First, let's find the slope of this line. The formula for slope is:
Change in y/Change in x or (y₂ - y₁)/(x₂-x₁)
Where x₁ = 0 x₂= 7 y₁ = 3 y₂ = 0
(y₂ - y₁)/(x₂-x₁)
= (0-3)/(7-0)
=-3/7
Now we can write the equation in point-slope form:
y-y₁ = m(x-x₁)
y - 3 = -3/7(x-0)
y-3=-3x/7
y=-3x/7 + 3
Now let's convert this to standard form, by making the y-intercept by itself:
Ax + By = C
y=-3x/7 + 3
Multiply through by 7
7(y) = 7(-3x/7) + 7(3)
7y = -3x + 21
3x + 7y = 21

Step-by-step explanation:
what value of x makes the equation 3(x-6)-8x=-2+5(2x+1) true ?
Answer:
x = (-7)/5
Step-by-step explanation:
Solve for x:
3 (x - 6) - 8 x = 5 (2 x + 1) - 2
3 (x - 6) = 3 x - 18:
3 x - 18 - 8 x = 5 (2 x + 1) - 2
Grouping like terms, 3 x - 8 x - 18 = (3 x - 8 x) - 18:
(3 x - 8 x) - 18 = 5 (2 x + 1) - 2
3 x - 8 x = -5 x:
-5 x - 18 = 5 (2 x + 1) - 2
5 (2 x + 1) = 10 x + 5:
-5 x - 18 = 10 x + 5 - 2
Add like terms. 5 - 2 = 3:
-5 x - 18 = 10 x + 3
Subtract 10 x from both sides:
(-5 x - 10 x) - 18 = (10 x - 10 x) + 3
-5 x - 10 x = -15 x:
-15 x - 18 = (10 x - 10 x) + 3
10 x - 10 x = 0:
-15 x - 18 = 3
Add 18 to both sides:
(18 - 18) - 15 x = 18 + 3
18 - 18 = 0:
-15 x = 3 + 18
3 + 18 = 21:
-15 x = 21
Divide both sides of -15 x = 21 by -15:
(-15 x)/(-15) = 21/(-15)
(-15)/(-15) = 1:
x = 21/(-15)
The gcd of 21 and -15 is 3, so 21/(-15) = (3×7)/(3 (-5)) = 3/3×7/(-5) = 7/(-5):
x = 7/(-5)
Multiply numerator and denominator of 7/(-5) by -1:
Answer: x = (-7)/5

How many solution does the inequality x>12 have explain
infinity numbers above 12
The inequality x > 12 has infinitely many solutions as it represents all numbers greater than 12 without any upper limit.
Explanation:The inequality x > 12 actually has infinitely many solutions, since any number greater than 12 satisfies the inequality condition.
In mathematics, inequalities that do not contain restrictions other than the comparative operator (in this case, '>') have a set of solutions that can be represented on a number line extending infinitely in one direction.
For example, if x > 12, then numbers such as 13, 14.5, 100, and 1234 are all solutions.
This can be visualized on a graph where x > 12 would be shown as an open interval starting from 12 and extending to the right toward infinity.

11. The completion of a chemical reaction is expressed by the equation y = 300 - 4x - XP, where y is
the number of seconds needed to complete the reaction and x is the temperature in degrees Celsius
at which the reaction occurs. If the reaction is complete in 160 sec, what is the temperature at which
the reaction occurs?
Answer:
The reaction ca occur at 10 degree Celsius or -14 degree Celsius.
Step-by-step explanation:
We are given the following in the question:
The completion of a chemical reaction is expressed by the equation
[tex]y = 300 - 4x -x^2[/tex]
where y is the number of seconds needed to complete the reaction and x is the temperature in degrees Celsius at which the reaction occurs.
We have to find the temperature at which the reaction occurs, if the completion time of reaction is 160 seconds.
Putting y = 160
[tex]160 = 300 - 4x -x^2\\x^2 + 4x - 140 = 0\\x^2 + 14x -10x -140 = 0\\x(x+14)-10(x+14)=0\\(x-10)(x+14) = 0\\(x-10) =0, (x+14) =0\\x = 10, x = -14[/tex]
Thus, the reaction ca occur at 10 degree Celsius or -14 degree Celsius.

The product of two whole numbers is 14391 and their difference is 6. What are the two numbers?
Answer:
117 and 123.
Step-by-step explanation:
If the 2 numbers are x and y we have the system of equations:
x - y = 6
xy = 14391
From the first equation y = X - 6 so substituting:
x(x - 6) = 14391
x^2 - 6x= 14391
x^2 - 6x - 14391 = 0
The prime factors of -13491 are -3*3*3*13*41
Now 3*3*13 = 117 and -3 * 41 = -123,
so the factors are:
(x - 123)(x + 117) = 0.
x = 123, -117.
As x is a whole number we take the positive value 123.
So x = 123 and y = 123 - 6 = 117.

Where is the vertex of the equation?y = x2 – 18x + 80
Answer:
vertex = (9, - 1 )
Step-by-step explanation:
Given a quadratic in standard form, y = ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]
y = x² - 18x + 80 ← is in standard form
with a = 1 and b = - 18, thus
[tex]x_{vertex}[/tex] = - [tex]\frac{-18}{2}[/tex] = 9
Substitute x = 9 into the function for corresponding value of y
y = 9² - 18(9) + 80 = 81 - 162 + 80 = - 1
Vertex = (9, - 1 )
