Answer:
the value if X is 8.
Step-by-step explanation:
firs,t, divide both sides of the equation.
2(4x-5)=54 -> 4x-5=27
then move the constant(-5) to the right hand side and change its sign
4x=27+5
add the numbers (27+5)
4x=32
divide both sides of the equation by 4
x=8
if you dont belive it, trying this
2(4×8-5

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
Let the percentage of tickets sold be = 93 %
The total number of tickets = 400 tickets
So , the number of tickets sold = ( 93% ) x 400
On simplifying the equation , we get
A = ( 93/100 ) x 400
A = 93 x 4
A = 372 tickets
Hence , the number of tickets is 372

Why is it important to determine if two lines on a graph are perpendicular?
Because when you know two lines are perpendicular you know all angles are 90 degrees and also any other lines you put through them you can figure out the angle and the other things because of that set rule of perpendicular lines having always 90 degree angles
The measure of an angle is 94°. What is the measure of its supplementary angle?
i need major help thanks!
Answer:
86 degrees
Step-by-step explanation:
94+86=180
Answer:
A supplementary angle is an angle that completes 180 degrees.
Thus, an 86 degree angle would be supplementary to a 94 degree angle.

Which set of ordered pairs could represent a function? (2, 3), (2, 2), (2, 4), (2, 9), (2, –2) (1, 5), (2, 6), (1, 6), (4, 5), (1, 4) (1, 0), (2, 0), (1, 3), (4, 3), (5, 7) (5, 1), (7, 3), (9, 5), (11, 7), (13, 9)
Given:
The set of ordered pairs in the options:
(a) (2, 3), (2, 2), (2, 4), (2, 9), (2, –2)
(b) (1, 5), (2, 6), (1, 6), (4, 5), (1, 4)
(c) (1, 0), (2, 0), (1, 3), (4, 3), (5, 7)
(d) (5, 1), (7, 3), (9, 5), (11, 7), (13, 9)
To find:
The set of ordered pairs that could represent a function.
Solution:
A set of ordered pairs represent a function, if there exist unique output (y-value) for each input (x-value).
In option (a) we have, five output values y=3,2,4,9,-2 for single input x=2. So, it is not a function.
In option (b) we have, three output values y=5,6,4 for single input x=1. So, it is not a function.
In option (c) we have, two output values y=0,3 for single input x=1. So, it is not a function.
In option (d), all inputs has unique output.
Therefore, the correct option is (d).

7, 7, 3 can be side lengths
3, 7, 14 cannot be side lengths
9.9, 25.0, 15.6 can be side lengths
Step-by-step explanation:
The rule for determining if three length can make up a triangle is to consider the length of any of the two and compare with the third length to check if it's greater.
mathematically, assume that a, b, c are three lengths. they will only form a triangle if these three conditions are true.
a + b > c;
b + c > a;
a + c > b;
That is the reason the only 3,7,14 cannot form a triangle because 3 + 4 < 14

The football team has a total of 350 jerseys there are 154 medium-sized jerseys. What percent of the jerseys are medium-sized jerseys?
Answer:
44% of the jerseys are medium sized.
Step-by-step explanation:
Total jerseys football team has = 350
Medium-sized jerseys = 154
We need to find what percent of the jerseys are medium-sized jerseys.
The formula used will be: [tex]Percent\:of\:medium\:size\:jerseys=\frac{Medium\:size\:jerseys}{Total\:jersey}\times 100[/tex]
Putting values and finding percentage
[tex]Percent\:of\:medium\:size\:jerseys=\frac{Medium\:size\:jerseys}{Total\:jersey}\times 100[/tex]
[tex]Percent\:of\:medium\:size\:jerseys=\frac{154}{350}\times 100\\Percent\:of\:medium\:size\:jerseys=0.44\times 100\\Percent\:of\:medium\:size\:jerseys=44\%[/tex]
So, 44% of the jerseys are medium sized.

Write the equation of a line that is perpendicular to the given line and that passes through the
given point.
y-2= 7/3 (x + 5);(-4,9)
Oy-9=-3/7(x-4)
Oy-9= 3/7(x-4)
Oy- 9= -3/7(x+4)
Oy- 9= -3/7(x+4)
Answer:
[tex]y-9=-\frac{3}{7} (x+4)[/tex]
Step-by-step explanation:
Slopes are negative reciprocals when two lines are perpendicular
[tex]m= - \frac {3}{7}[/tex]
Equation of straight line in point-slope form is given as
[tex]y-y_1=m(x-x_2)[/tex]
Here [tex](x_1, y_1)= (-4, 9)[/tex]
[tex]y-9=-\frac{3}{7} (x+4)[/tex]
The equation of line passes through the point (-4, 9) will be;
⇒ y - 9 = - 3/7x - 12/7
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The point on the line are (-4, 9).
And, The perpendicular line is,
⇒ y - 2 = 7/3 (x + 5)
Now,
Since, The equation of line passes through the point (- 4, 9).
So, We need to find the slope of the line.
Since, The product of the slope of perpendicular line is - 1.
Hence, Slope of the perpendicular line is,
⇒ y - 2 = 7/3 (x + 5)
m = dy/dx = 7/3
m = 7/3
Thus, The equation of line with slope - 3/7 is,
⇒ y - 9 = - 3/7 (x - (-4))
⇒ y - 9 = - 3/7 (x + 4)
⇒ y - 9 = - 3/7x - 12/7
⇒ y = - 3/7x + 9 - 12/7
⇒ y = - 3/7x + 51/7
Therefore, The equation of line passes through the point (-4, 9) will be;
⇒ y - 9 = - 3/7x - 12/7

How do you divide fraction (in the simplest form)
Answer:
1/3 divided by 5/4
So we divide both the top by 3 and the bottom by 3 and so our final answer would be 4 over 7. So that's our simplified fraction
-------------
Invert and multiply:
Take the reciprocal of the divisor and multiply the dividend. The top and bottom are being multiplied by the same number. Since that number is the reciprocal of the bottom part, the bottom becomes one.
Find the biggest common number:
It could be said to be a "more correct" method. This is the correct way since, you can’t divide apples by oranges in the same way as you can’t divide fifths by fourths.
Answer:
Step-by-step explanation:
You find the biggest common number you can divide the numerator and denominator.
For example, we have our answer is 8/12 so you can divide it into 1,2, and 4. 8/12 divide by 1/1 = 8/12. 8/12 / 2/2 = 4/6. 8/12 / 4/4 = 2/3.
So the answer is 2/3.
