Answer:
2x=50
Step-by-step explanation:
Hi there,
Your question is "twice a number (x) is fifty"
Recall how a number is represented by x.
Twice a number would be represented as 2x.
Therefore, to represent that twice a number is equal to 50, that would result in the expression: [tex]2x=50[/tex]
If you're looking to solve this equation, it's often best to think about the "reverse" of the current equation.
Notice how 2 is multiplying the x.
To isolate x, divide that side by 2.
However, recall that whatever is done to one side of an equation must also be done to the other side of the equation. Therefore, you will need to divide both sides by 2.
[tex]2x=50[/tex]
[tex]\frac{2x}{2} = \frac{50}{2}[/tex]
[tex]x=25[/tex]
Equation: [tex]2x=50[/tex]
Solving for x: 25
Hope that helps!

Guadrilateral whose vertices are A(-2-2),B(5-2),C(4-3) and D(-3,-3)what kind of a guadrilatetal is ABCD?
Answer:
The quadrilateral ABCD is a parallelogram
Step-by-step explanation:
The vertices of the quadrilateral ABCD are;
A(-2 -2), B(5, -2), C(4, -3)and D(-3, -3)
The slope of segment [tex]\overline {AB}[/tex] = (-2 - (-2))/(5 - (-2)) = 0
The length of segment [tex]\overline {AB}[/tex] = 5 - (-2) = 7 (points having the same y-coordinates)
The slope of segment [tex]\overline {AD}[/tex] = (-3 - (-2))/(-3 - (-2)) = 1
The length of segment [tex]\overline {AD}[/tex] = √((-3 - (-2))² + (-3 - (-2))²) = √2
The slope of segment [tex]\overline {DC}[/tex] = (-3 - (-3))/(-3 - 4) = 0
The length of segment [tex]\overline {DC}[/tex] = 4 - (-3) = 7 (points having the same y-coordinates)
The slope of segment [tex]\overline {BC}[/tex] = (-3 - (-2))/(4 - 5) = 1
The length of segment [tex]\overline {AD}[/tex] = √((4 - 5)² + (-3 - (-2))²) = √2
Therefore;
The opposite sites of the quadrilateral ABCD are equal; [tex]\overline {AB}[/tex] = [tex]\overline {DC}[/tex], [tex]\overline {AD}[/tex] = [tex]\overline {BC}[/tex]
Given that the slope of a line gives the inclination of the line on a graph, we have;
The opposite sites of the quadrilateral are parallel; [tex]\overline {AB}[/tex] ║ [tex]\overline {DC}[/tex], [tex]\overline {AD}[/tex] ║ [tex]\overline {BC}[/tex]
Therefore the quadrilateral ABCD is a parallelogram because the opposite sides of the quadrilateral ABCD are parallel.

OD. 24 л cm3
ILL GIVE BRAINLIST:)
Answer:
[tex]24\pi \: cm {}^{2} [/tex]
Step-by-step explanation:
The area of a cone is
[tex]\pi \times r {}^{2} + \pi \times r \times \sqrt{ {r }^{2} + {h}^{2} } [/tex]
The volume of the conical paper cup will be option (D) 24π
What is Cone?A cone is a three-dimensional geometric shape that tapers smoothly from a flat base to a point called the vertex.A cone is formed by a set of line segments, half-lines, or lines connecting a common point, the vertex, to all of the points on a base that is in a plane that does not contain the vertex.Cone is a solid or hollow object which tapers from a circular or roughly circular base to a point.What are steps to solve this problem?The steps are as follow:
Given:r = base radius = 3 cm
h = height of cone = 8 cm
V = volume of cone = (1/3)πr²h.
V = (1/3)π*3²*8.
V = 24π
So, the volume of the conical paper cup will be option (D) 24π

Step-by-step explanation:
68÷8= 8.5
8.5×5= 42.5 miles
we use the numbers given to us because we are finding the estimate.
our estimate is correct because 68km= 42.3 miles
Answer:
The exact answer is 42.25 miles
Step-by-step explanation:
divide 68 by 8 and get 8.5. Multiply 8.5 by the 5 so you get 42.5. Which is a super close estimate.

Sketch the graph of each linear inequality
Answer:
Step-by-step explanation:
In an inequality, sign of greater than or less than decides that the graph of the line will be a dotted line.
And sign of greater than means area above the dotted line.
Table for input output values,
x -4 0 4 6
y -3 -4 -5 -5.5
Plot these points and join them by a dotted line.
Now we shade the area above the dotted line to show the solution area of the inequality.

Answer:
1. 20x+8=48 2. x=2 3. the area of the square is 144units^2
Step-by-step explanation:
assuming its a perfect 4 sides square the total perimeter would be 5x + 2 units multiplied by 4 = the perimeter so 20x+8 = 48
20x+8=48
subtract 8 from both sides
20x=40
divide 20
x = 2 units
For area plug x back into 5x+2 and you will get 12 units for one side and all sides here should be 12 units so multiply one side with another
12 x 12 = 144 units^2
Answer:
Well I answered in the comments, but I need points so the answers are (in order) 12, 2, and 144
Step-by-step explanation:
Since it's a square, the sides will be the same length. If the perimeter is 48, then you divide 48 by 4 and you will have 12- your answer.
For x, subtract 2 from 12 to get ten, then divide that by five to get your answer which would be 2.
If the side length is 12, you square that and 12 squared is 144.

what is a way that i can get 3x and 2x to cancel out in this problem? i need to get - 5y = -13 and + 15y = -3 alone.
problem:
3x + 5y = -13
2x + 15y= 3
Answer:
For 3x + 5y = -13 the answer is x= -13/3 + 5y/3
and for 2x + 15y=3 the answer x= 1.5 + (-15y/2)
Step-by-step:
For 3x+5y=-13 you have to add 5y on both sides. Then you have to divide by 3 on both sides and cancel out the common factor of 3. Then you would get x= 13/3 + 5y/3.
For 2x + 15y=3 you have to subtract 15y on both sides of the equation. You should have 2x=3 + (-15y). Then divide by 2 on both sides. 3 divided by 2 is 1.5 and -15y divided by 2 is -15y/2 since 2 doesn't have the same variable. so the answer should be x= 1.5 + (-15y/2).

Consider an equilateral triangle that is small enough to fit in your pocket. Now consider an equilateral triangle that is big enough to fill a movie screen! What must be true about the measure of each of the interior angles for these two triangles? Does the size of a triangle influence its angle measures? What about other polygons?
Answer:
Step-by-step explanation:
First Question: Equilateral triangles all have the same interior angles. 60 degrees. Size does not make the angles bigger. It makes the sides bigger.
Second Question: No the size does not influence the size of the interior angle.
Third Question: That's true for all polygons. Size is not affect the interior angle size.
