Ac=3x+6 and CD=2x+14 what is the value of x
Answer:
[tex]x=8[/tex]
Step-by-step explanation:
We have been given that [tex]AC=3x+6[/tex] and [tex]CD=2x+14[/tex].
To solve for x, we are assuming that C is the midpoint of segment AD and we will equate both expressions as:
[tex]3x+6=2x+14[/tex]
[tex]3x-2x+6=2x-2x+14[/tex]
[tex]x+6=14[/tex]
[tex]x+6-6=14-6[/tex]
[tex]x=8[/tex]
Therefore, the value of x is 8.

How tall would a stack of 1000 pennies be in centimeters?
To calculate the height of a stack of 1000 pennies, multiply the thickness of one penny (0.1524 cm) by 1000. The total height would be 152.4 cm.
Explanation:Calculating the Height of a Stack of 1000 Pennies
To calculate the height of a stack of 1000 pennies, we first need to know the thickness of one penny. Unfortunately, the data provided talks about the volume of a stack of 100 bills, which is not directly relevant to our problem. However, by using the correct information, we find that a US penny is approximately 0.0598 inches (or 0.1524 cm) in thickness. So the calculation for the height of 1000 pennies stacked would be as follows:
Thickness of one penny = 0.1524 cmTotal height = 0.1524 cm/penny × 1000 penniesTotal height = 152.4 cmThus, the height of a stack of 1000 pennies would be 152.4 centimeters.

How can one thirdx − 2 = one fourthx + 11 be set up as a system of equations?
3y − x = −6
4y − x = 44
3y + x = −6
4y + x = 44
3y − 3x = −6
4y − 4x = 44
3y + 3x = −6
4y + 4x = 44
Answer: Hello!
we have that:
one third x − 2 = one fourth x + 11
this means:
(1/3)x - 2 = (1/4)x + 11
if this are equal numbers, we can write it as:
(1/3)x - 2 = y = (1/4)x + 11
now we have the system of equations:
(1/3)x - 2 = y
(1/4)x + 11 = y
if we "simplify" the rational therm in each equation, we get:
3*(1/3)x - 3*2 = 3y
x - 6 = 3y
and
4*(1/4)x + 4*11 = 4y
x + 44 = 4y
Then our system of equations is:
x - 6 = 3y
x + 44 = 4y
Now we can subtract x in each side of both equations:
-6 = 3y - x
44 = 4y - x
Then the right option is the first one.
3y - x = -6
4y - x = 44

What is the measure of a base angle of an isosceles triangle if the vertex angle measures 38° and the two congruent sides each measure 21 units?
The measure of a base angle in an isosceles triangle with a vertex angle of 38° is 71°, as isosceles triangles have two equal base angles and the total sum of angles in any triangle is 180°.
Explanation:To calculate the measure of a base angle in an isosceles triangle, we need to remember that the sum of angles in a triangle is always 180°. Given that we have a vertex angle of 38°, we subtract that from 180° to find the sum of the two base angles. Since it's an isosceles triangle, these angles are equal:
180° - 38° = 142° (sum of both base angles)142° / 2 = 71° (measure of one base angle)Therefore, the measure of one base angle in this isosceles triangle is 71°.
The measure of each base angle of an isosceles triangle is 71°.
Explanation:An isosceles triangle has two congruent sides and two congruent base angles. In this case, the vertex angle measures 38° and the congruent sides each measure 21 units. To find the measure of a base angle, we can use the fact that the sum of the angles in a triangle is 180°. Since the vertex angle is 38°, the sum of the base angles is 180° - 38° = 142°. Since the base angles are congruent, we can divide 142° by 2 to find the measure of each base angle.
142° / 2 = 71°
Therefore, the measure of each base angle is 71°.

What is the point slope equation of the line with slope -12 that goes through the points (5, 3)?
Answer:
y = -12x + 63
Step-by-step explanation:
- The equation of a line in a cartesian coordinate system is given by the following linear relationship:
y = mx + c
- The constants m and c are to be determined.
- The constant m denotes the slope of the line which is given as -12.
- To evaluate constant c we will plug the slope m = -12 and use the given point ( 5 , 3 ) as the lines passes through it. Hence, we have:
y = -12x + c
3 = -12(5) + c
3 = - 60 + c
c = 63
- Then the equation of the line can be expressed by plugging in the constants m and c as follows:
y = -12x + 63
If 3 is added to a number and the sum is tripledtripled, the result is 27 more than the number. find the number.
To solve this problem, let us say that the number is called x and let us do this step by step.
1st step: 3 is added to the number, therefore:
x + 3
2nd step: the sum is tripled, therefore:
3 (x + 3)
3rd step: the result in the 2nd step is equal to 27 more than the original number, therefore:
3 (x + 3) = x + 27
4th step: find for the value of x using the equation
3 x + 9 = x + 27
3 x – x = 27 – 9
2 x = 18
x = 9
Answer:
The number is 9
Describe how the graph of y=|x|-12 is like the graph of y=|x| and how it is different?
Answer:
Both functions are similar, because basically they have the same behaviour, but the difference is that they start from a different vertex. The reason of this is because [tex]y=|x|-12[/tex] is a translation of [tex]y=|x|[/tex].
Basically, the first function is similar to the second one, but translated downwards 12 units.
So, they are similar in behaviour, we could say parallel, but different on the position of the vertex, the first is at y=-12, and the second one at y=0.
The graph of each function is attached, there you can observe the similarity and different we mentioned before.

Answer: Option 'D' is correct.
Step-by-step explanation:
Since we have given that
[tex]x^3+\frac{1}{3}x^4+6x+5[/tex]
Coefficient of the terms are as follows:
Coefficient of x³ is 1
Coefficient of x⁴ is [tex]\frac{1}{3}[/tex]
Coefficient of x is 6
Constant term is 5
Hence, coefficient of the term with the power of 3 is 1.
Therefore, Option 'D' is correct.
How many values of θ will satisfy tan-1 0 = θ when 0º<θ<90º?
Use the information in the figure. If m∠F = 76°, find m∠E
Answer:
m∠E=52°.
Step-by-step explanation:
The given triangle has two sides equal. In isosceles triangle two sides are equal and base angles are equal.m∠E=m∠D.
Let m∠D=m∠E= x
The sum of angles in any triangle is 180°.
Or,
x+x+76= 180
Addling like terms :
2x+76=180
Subtracting 76 both sides,
2x=104.
Dividing by 2:
x=52.
m∠E= 52°.
