Answer:
Order equivalent equations of 2(x−3) = 4x to solve for x.
Step-by-step explanation:
So, to do this we must do distrubition so 2 times x = 2x -3 times 2 = -6 and 4x times 2 equals 6x and subtract the 6x from 6 which equals x sotherefore 2 and 2 cancels out so you're left with x=x
ANSWER: x=x
A scale model of a rectangular living room is 6 3/4 inches by 5 1/2 inches. If 1 inch represents 3 feet of the actual room, find the area of the actual room.
The actual area of the room after unit conversion will be equal to 334 1/8 feet².
What is area?An object's area is how much space it takes up in two dimensions. It is the measurement of the number of unit squares that completely encompass the surface of a compact figure. The squared unit, which is frequently expressed as inches, square feet, etc., is the accepted unit of area.
As per the data mentioned in the question,
Let the length of the room, l = 6 3/4 inches = 27/4 inches
1 inch = 3 feet
27/4 inch = 81/4 feet
Let the width of the room, w = 5 1/2 inches = 11/2 inches
1 inch = 3 feet
11/2 inches = 33/2 feet
Now, use the formula of the area of the rectangle,
A = wl
A = 33/2 × 81/4
A = 2672/8 feet²
Or, it can be written in mixed fraction form as 334 1/8 feet².

Find the value of xxx in the triangle shown below.
Answer:
[tex]\underline{\boxed{\sf x=74^o}}[/tex]
Step-by-step explanation:
The given triangle is in isosceles triangle because it has two congruent sides. Angles across from the congruent sides are also congruen, so the angle without a label measures x.
(3 angles in a triangle add up to 180°).
Equation:- [tex]\sf x^o+x^o+32^o=180^o[/tex]
Let's solve for x:-
[tex]\sf x+x+32=180[/tex]
[tex]\sf 2x+32=180[/tex] (Simplify)
[tex]\sf 2x+32-32=180-32[/tex] (Subtract)
[tex]\sf 2x=148[/tex]
[tex]\sf \dfrac{2x}{2} =\dfrac{148}{2}[/tex] (Divide)
[tex]\sf x=74^o[/tex]
The general expressions for consecutive multiples of 3 are 3N, 3(N + 1), 3(N + 2), etc.,
where N is some unspecified integer. Find four consecutive multiples of 3 such that 5
times the sum of the first and fourth is 6 less than 13 times the third.
These 4 consecutive multiples of 3 are of the form
3N, 3 (N + 1), 3 (N + 2), 3 (N + 3)
The given constraint is captured in the equation
5 (3N + 3 (N + 3)) = 13 (3 (N + 2)) - 6
Solve for N :
5 (3N + 3N + 9) = 13 (3N + 6) - 6
5 (6N + 9) = 13 (3N + 6) - 6
30N + 45 = 39N + 78 - 6
30N + 45 = 39N + 72
30N - 39N = 72 - 45
-9N = 27
N = 27/(-9)
N = -3
Then the 5 consecutive multiples of 3 are
-9, -6, -3, 0
Ricardo calculates a line of best fit for a data set with integer x-values 1 through 6. Complete the sentence with the correct word
Using a line of best fit with the equation y = -3x+21 to predict the value of y when x = 10 is an example of
Choose...
correlation
extrapolation
interpolation
causation
This type of prediction is extrapolation
Give the equation for the line of best fit expressed as:
y = -3x + 21
If x = 10, substitute the value of x into the function to get y
y = -3(10) + 21
y = -30 + 21
y = -9

What fractional part of one semicircle does the labeled angle represent? Express your answer as a fraction in simplest terms. Then, express the labeled angle in radian measure
The fraction of the labelled angle is: 2/3 of one semicircle.
In radians, it is: 2.0944 rad.
Recall:
One semicircle = 3.1416 radian
One semicircle = 180 degrees
Thus, 120 degrees of a semicircle as a fraction would be:
120/180 = 2/3Therefore, 120 degrees equals 2/3 semicircle.
Convert to radians:
One semicircle = 3.1416 radian
2/3 semicircle = x
Cross multiply[tex]x = 3.1416 \times \frac{2}{3} \\\\\mathbf{x = 2.0944 $ rad}[/tex]
Therefore, the fraction of the labelled angle is: 2/3 of one semicircle.

=
Answer:
5 is the slope
Step-by-step explanation:
Because the equation is y=mx+b
m=slope and b=y intercept
Answer:
The slope of the line y = 5x + 4 is 5.
Step-by-step explanation:
In the equation y = mx + b,
m represents the slope
b represents the y-intercept.
In the equation y = 5x + 4, 5 takes place of m. Since this is the case, m = 5, or 5 is the slope.

What is the reciprocal of 5
Answer:
1/5 or 0.2
Step-by-step explanation:
Reciprocal is when you flip the number
5 = 5/1 so flip the 1 and 5 to get 1/5
In order to find the reciprocal of a number, we should flop it over, like so:-
[tex]\sf{The~reciprocal~of~a~is~\displaystyle\frac{1}{a}}[/tex]
According to the formula, the reciprocal of 5 is:-

The perimeter of a rectangle is 50 cm, the length is 10 cm. What is the width? Area?
Width=
area=
Answer:
Width: 15 cm
Area: 150 cm squared
Step-by-step explanation:
I did 10 + 10 to get the total of the two sides of the rectangle.
I subtracted 20 from 50 to get what the two widths are supposed to add up to.
The answer was 30 so I divided 30 by 2 to get what one width equals.
The width equals 15.
To get the area of a rectangle you have to multiply the length by the width which would be 150 cm squared.
Step-by-step explanation: the width is 15cm
