A carpenter makes tables and chairs. It takes 4 hours to make a table and 2 hours to make a chair. x represents the number of tables made each month y represents the number of chairs made each month What does the expression 4x+2y represent? A. the total number of hours used to make tables and chairs each month B. the total number of hours used to make 4 tables and 2 chairs C. the total number of tables and chairs that are made each month D. the total number of tables and chairs that are made in 6 hours
Answer:
A. the total number of hours used to make tables and chairs each month
Step-by-step explanation:
x = number of tables made each month
y = number of chairs made each month
It takes 4 hours to make a table and 2 hours to make a chair.
4x + 2y
The total number of hours used to make tables and chairs each month = 4x + 2y
The correct answer is A
A. the total number of hours used to make tables and chairs each month

The Triangle Angle Sum Theorem states that the sum of all interior angles of a triangle add up to 180 degrees.
Only Amy proved the theorem because she used postulates and theorems to construct a logical argument to show that the interior angles in a triangle add up to 180 degrees.
What equation is the equation of the line, in point slope form, that has a slope of -1.8 and passes through the point (-0.5, 1.9) ?
Answer:
Third option[tex]y -1.9=-1.8(x+0,5)[/tex]Step-by-step explanation:
Slope = -1.8
(-0.5,1.9)
[tex]m =-1.8\\(-0.5 , 1.9) = (x_1 ,y_1)[/tex]
Substitute values into point slope form
[tex]y-y_1=m(x-x_1)\\\\y -1.9=-1.8(x -(-0.5))\\\\y -1.9 =-1.8(x+0.5)[/tex]
Answer:
y − 1.9 = −1.8 (x + 0.5)

Look at the two equations:
-3x + 6 = 21
- 3x + 6 <21
Which statement best describes the process used to solve the equations?
In both cases, subtract 6 from both sides, but reverse the inequality sign when doing that for the inequality.
In both cases, divide by -3 on both sides, but reverse the inequality sign when doing that for the inequality.
The process is exactly the same for solving the equation and solving the inequality.
The process for solving the equation is entirely different from solving the inequality.
Answer:
>21 -3×+6 = 20 plus 1 equals 21
Answer:
The answer is B, In both cases, divide by –3 on both sides, but reverse the inequality sign when doing that for the inequality.

The sum of the angle measures of a quadrilateral is 360°. Write and solve an equation to find the value of X.
Answer:
1). x° + 100° + 120° + 100° = 360°
2). x = 40
Step-by-step explanation:
Formula for the sum of the interior angles of a polygon = [tex](n-2)\times 180[/tex]
Where n = number of sides of the polygon
From the picture attached,
For n = 4,
Sum of the interior angles of the given polygon = (4 - 2) × 180°
= 360°
Therefore, equation for the sum of interior angles will be,
x° + 100° + 120° + 100° = 360°
x° + 320° = 360°
x° = 360° - 320°
x° = 40°
When adding 2/3 + 4/5, what step must be completed first?
A)Finding the least common denominator.
B)Reducing the fractions.
C)Adding the numerators, but keeping the denominators.
D)Adding the denominators, but keeping the numerators.
Answer:
(A) Finding the least common denominator.
In order to add the fractions 2/3 + 4/5 the least common factor of 3 and 5 has been taken in the first step thus,option (A) is correct.
What is the lowest common multiple?The lowest common multiple is the smallest multiple which is common between any two numbers.
It means we can divide both numbers by that and that is the smallest number by which both dived.
For example, LCM of 2 and 8 is 8.
As per the given two fractions,
2/3 + 4/5,
The least common factor of 3 and 5 is 15
Thus, (10 + 12)/15
Thus, in the first step, we have taken LCM.
Hence "In order to add the fractions 2/3 + 4/5 the least common factor of 3 and 5 has been taken in the first step".

The measure of an angle is 10 degrees more than its supplement. What is the measure of
the smaller angle?
Supplementary angles are angles that add up to 180 degrees.
Angle 1 = x
Angle 2 = x + 10
Since they are supplementary, we can set then equal to 180
x + x + 10 = 180
Combine like terms
2x + 10 = 180
Subtract 10 from both sides
2x = 170
Divide both sides by 2
x = 85
Angle 1 = 85 degrees
Angle 2 = 85 + 10 = 95 degrees

Which expressions are equivalent to 5^12 x 5^8? A. 25^20 B. (25^5)^4 C. (5^3 x 5^2)^4 D. (5^5)^4
Hey there! I'm happy to help!
When multiplying numbers with exponents, all you do is add the exponent numbers, so 5^12×5^8=5^20.
A is not equal to this.
B is also not equal to this. B is 25^20.
C is wrong as well. It is 5^5.
This leaves us with D, which does evaluate to 5^20. If you raise a power to a power you multiply the exponent numbers, and 5(4)=20.
The answer is D. (5^5)^4.
Have a wonderful day! :D
5^12 * 5^8
5^12+8
5^20
The only option that is equal to that is D.
(5^5)^4
5^5*4
5^20

Quadrilateral RAPS is located at the vertices
R(-4,1), A(-3, 4), P(0,5), S(-1,1). Where will points
R", A", P", S", be located after the quadrilateral has been reflected
across the line y - x and then rotated 180° about the origin?
Answer:
R''(-1, 4), A''(-4, 3), P''(-5, 0), S''(-1, 1)
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new position. Types of transformation include dilation, reflection, translation and rotation.
If a point A(x, y) is reflected over the line y = x, the new point is at A'(y, x)
If a point A(x, y) is rotated 180° clockwise about the origin, the new location is at A'(-x, -y)
Since Quadrilateral RAPS is located at the vertices R(-4,1), A(-3, 4), P(0,5), S(-1,1), After been reflected across the line y = x, the new locations are at:
R'(1, -4), A'(4, -3), P'(5, 0), S'(1, -1)
Then the rotation of the points R'(1, -4), A'(4, -3), P'(5, 0), S'(1, -1) 180° about the origin gives:
R''(-1, 4), A''(-4, 3), P''(-5, 0), S''(-1, 1)
