16. Find the value of y.
y + (2x -12) = 180 (since they are supplementary angles)
(2x-12) = 96 ( since they are alternate exterior angle)
2x = 96 + 12
2x = 108
x = 108/2
x = 54.
y+( 2x-12)=180
y+(2× 54 -12) = 180
y + (108-12) = 180
y + 96 = 180
y= 180-96
y = 84.
Five times of a positive integer is less than twice its square by 3.
Find the integer.
Answer:
The positive integer is 3.
Step-by-step explanation:
Let 'x' be the integer
Given that five times of a positive integer is less than twice its square by 3.
so
5 times of x = [tex]5x[/tex]
3 less than twice of the square of x = [tex]2x^{2} - 3[/tex]
so the equation becomes
[tex]5x = 2x^{2} - 3[/tex]
[tex]2x^2-5x-3=0[/tex]
Factorise
[tex]\left(2x+1\right)\left(x-3\right)=0[/tex]
Using the zero factor principle
if ab=0, then a=0 or b=0 (or both a=0 and b=0)
[tex]2x+1=0\quad \mathrm{or}\quad \:x-3=0[/tex]
solving
[tex]2x+1=0[/tex]
Subtract 1 from both sides
[tex]2x+1-1=0-1[/tex]
Simplify
[tex]2x=-1[/tex]
Divide both sides by 2
[tex]\frac{2x}{2}=\frac{-1}{2}[/tex]
Simplify
[tex]x=-\frac{1}{2}[/tex]
Also solving
[tex]x-3=0[/tex]
Add 3 to both sides
[tex]x-3+3=0+3[/tex]
simplify
[tex]x=3[/tex]
Thus, we got integers:
x = 3 or x = -1/2
As x can not be a negative integer according to the question.Therefore, the positive integer is 3.
find the value of the variable and BC, if B is between A and C.
AB = 5x, BC = 3x-1, AC = 47
Answer:
17
Step-by-step explanation:
AC = AB + BC
Since we know what each variable equals, we can write out the equation as shown:
47 = 5x + 3x - 1
Combining like terms:
47 = 8x - 1
Add 1 on both sides:
48 = 8x
Divide 8 on both sides:
X = 6
Now that we know what X equals, we can solve BC.
BC = 3(6) - 1
BC = 18 - 1
BC = 17
Therefore BC = 17.

Answer:
Simplify both of them
Step-by-step explanation:
After simplify we get both ratio 2:7 and 10000:35000 are equal.
What is Ratio?
A ratio indicates how many times one number contain in another number.
Given that;
Both ratio are;
2:7 and 10000:35000
Now, Solve the ratio for simplifying;
Ratios are 2:7 and 10000:35000
First ratio is 2 : 7.
Clearly, This is already in simplest form.
Second ratio is 10000:35000
It can be written as;
10000:35000 = 10000/35000
= 10/35
= 2/7
Thus, After simplify we get both ratio 2:7 and 10000:35000 are equal.

Step-by-step explanation:
You are offered two jobs that you like. One job pays an hourly rate of $15.00 per hour for a 40-hour work week. Employees can take a two-week paid vacation. The employer says you will work about 5 hours of overtime per week at time-and-a-half pay. The other job pays $38,000 per year. You will be expected to work at least 55 hours per week, and you will have two weeks vacation and sick leave. Which job would you choose? Why?
Answer:
Second Job
Step-by-step explanation:
I would take the second job because you will make more. And it has sick time in addition to vacation.
First job:
$15x40=$600 then add in overtime which will be paid at $22.50 (time and half) so $22.50x5=$112.50. Add the two together $600+112.50=$712.50 weekly.
Second job:
$38,000/52=$730.77 weekly

Each hexagon tile has an area of LaTeX: 18\sqrt{3} 18 3 in.2 . Solve for x. Then find the exact length of each side of the hexagon. (Hint: Six equilateral triangles make one hexagon.)
Answer:
The length of the side of the hexagon is [tex]2\sqrt{3}[/tex] inches.
Step-by-step explanation:
According to this question, we have a regular hexagon with a surface area of [tex]18\sqrt{3}\,in^{2}[/tex]. From Geometry, we know that all regular hexagons can be formed by six regular triangles, since the angle of one complete revolution (360º) divided by the number of triangles is equal to the internal angle of each triangle (60º). Then, the area of each triangle is found after dividing the complete area by the number of regular triangles:
[tex]A_{\triangle} = \frac{18\sqrt{3}\,in^{2}}{6}[/tex]
[tex]A_{\triangle} = 3\sqrt{3}\,in^{2}[/tex]
The area of the triangle as a function of the length of the side of the hexagon ([tex]l[/tex]), measured in inches, is determined by this equation:
[tex]A_{\triangle} = \frac{\sqrt{3}}{4} \cdot l^{2}[/tex] (1)
If we know that [tex]A_{\triangle} = 3\sqrt{3}\,in^{2}[/tex], then the length of the side of the hexagon is:
[tex]\frac{4}{\sqrt{3}}\cdot A_{\triangle} = l^{2}[/tex]
[tex]l^{2} = \frac{4\cdot \sqrt{3}}{3} \cdot A_{\triangle}[/tex]
[tex]l = 2\sqrt{\frac{\sqrt{3}}{3}\cdot A_{\triangle} }[/tex]
[tex]l = 2\sqrt{3}\,in[/tex]
The length of the side of the hexagon is [tex]2\sqrt{3}[/tex] inches.

This question has how many solutions
Answer:
x=32 so one solution only
Step-by-step explanation:
6(x-8)+10=5x-6
6x-48+10=5x-6
6x-38=5x-6
x-38=-6
x=32
Therefore, the equation only has one solution which is x=32
Answer:
This question has 1 solution.
Step-by-step explanation:
Solve for X
First, distribute:
6x - 48 +10 = 5x - 6
Second, combine like terms:
6x - 38 = 5x - 6
Third, move like signs to one side:

What is the y-intercept of this line: y= 7x-5
Answer:
- 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 7x - 5 ← is in slope- intercept form
with y- intercept c = - 5
The y-intercept of the line y = 7x - 5 is -5.
To find the y-intercept of the line represented by the equation y = 7x - 5, we need to determine the value of y when x is equal to zero. The y-intercept represents the point where the line crosses or intersects the y-axis.
In this case, when we substitute x = 0 into the equation, we get:
y = 7(0) - 5
y = -5
Therefore, the y-intercept of the line y = 7x - 5 is -5. This means that the line intersects the y-axis at the point (0, -5), with the y-coordinate being -5. Graphically, this indicates that the line crosses the y-axis at a height of -5 units.

Answer:
The equation of the line passing through the points (4, 6) and (0, 6) will be:
y = 6The graph of the equation y = 6 is also attached.
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptGiven the points
(4, 6)(0, 6)Finding the slope between (4, 6)and (0, 6).
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [6 - 6] / [0 - 4]
= 0 / -4
= 0
Thus, the slope of the line = m = 0
The slope m = 0 means the line is horizontal. Because the slope of the horizontal line is 0.
As the y-values are not changing with respect to the x-values.
Therefore,
The equation of the line passing through the points (4, 6) and (0, 6) will be:
y = 6The graph of the equation y = 6 is also attached.

Do NOT answer just for points.
Answer:
y+4=-3(x+1)
Step-by-step explanation:
point slope form = y-y1=m(x-x1)
so plug in the numbers
y - -4 = -3 (x - - 1)
if there are two negatives it becomes a positive so your final answer is y + 4 = -3 (x +1)
