Answer:
BC = 3
Step-by-step explanation:
If you picture A, B, and C on a line, the first part of the line, AB, has a length of 5 and the total line, AC, has a length of 8 . Means that the second part of the line, BC, has a length of 3 because you would add the length of both the first and second part of the line in order to get the total length of the line.
AB + BC = AC
5 + BC = 8
BC = 3

The inequality that represents this graph is y < 2x + 2.
What are inequalities and their types?Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.
The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
a is less than or equal to b when a notation like a ≤ b.
a is bigger or equal value of an is indicated by the notation a ≥ b.
The dotted line represents strictly less than or greater than.
From the graph, we can conclude that when x = 0, y = 2, and when x = 1 y = 4, and values of y are strictly less.
∴ The inequality that represents this graph is y < 2x + 2.

For a field trip 23 students rode in cars and the rest filled five buses. How many students were in each bus if 288 students were on the trip?
Answer: First, you start with the equation:
9
x
+
4
=
472
Since four students rode in cars, you want to eliminate this part of the problem to find how many students actually rode in the buses
So you would subtract
4
from both sides and get:
9
x
=
468
Finally, you would divide both sides by
9
and get
52

How do I write an equation that would allow someone to find the value of R
Answer:
R+239=3501
Step-by-step explanation:
Add the three 1,167 values together and you get 3,501. Then, because we know a portion of the three blocks is equal to 239, add it so when we solve for R, 239 is subtracted from the total.
As for solving it,
Subtract 239 on both sides, and R is 3501-239 = 3262

Answer:
5) 76°
7) 34°
Step-by-step explanation:
5) An angle bisector creates two congruent angles, so ...
∠WUV = 2(∠1)
9x +4 = 2(5x -2)
9x +4 = 10x -4
8 = x
Then ...
∠WUV = 9(8) +4 = 76
The measure of angle WUV is 76°.
__
7) An angle bisector creates two congruent angles, so ...
∠1 = ∠2
2x -3 = x +7
x = 10 . . . . . . . . add 3-x
Then ...
∠XVW = 2(∠2) = 2(10 +7) = 34
The measure of angle XVW is 34°.

A line segment has endpoints at (-1, 4) and (4,1). Which reflection will produce an image with endpoints at (-4,1)
and (-1,-4)?
a reflection of the line segment across the x-axis
O a reflection of the line segment across the y-axis
O a reflection of the line segment across the line y = x
O a reflection of the line segment across the line y = -X
Answer:B
Step-by-step explanation:
A reflection of the line segment across the line y = - x, will produce an image with endpoints at (- 4, 1) and (- 1, - 4).
What are transformations?Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.
Dilation: The preimage is scaled up or down to create the image.
Reflection: The picture is a preimage that has been reversed.
Rotation: Around a given point, the preimage is rotated to create the final image.
Translation: The image is translated and moved a fixed amount from the preimage.
We know, A reflection across the 180° about the origin transforms
(x, y) to (-x, - y)
Therefore A line segment has endpoints at (-1, 4) and (4,1) will have an image at (- 4, 1), and (- 1,- 4) is a reflection of the line segment across the line y = - x.

Sum of triangle: 180
So we know that:
7x + 3x + 8 + x + 7 = 180
Combine like terms:
11x + 15 = 180
11x = 165
x = 15
Plug in for x in order to find the angles.
You should be able to solve from here!
Answer:
m∠I = 22
m∠J = 53
m∠K = 105
Step-by-step explanation:
m∠I = (x + 7)
m∠J = (3x + 8)
m∠K = (7x)
m∠I + m∠J + m∠K = 180°
(x + 7) + (3x + 8) + (7x) = 180
x + 7 + 3x + 8 + 7x = 180
11x + 15 = 180
11x = 165
x = 15
m∠I = 15 + 7 = 22
m∠J = 3(15) + 8 = 53
m∠K = 7(15) = 105
8.51348434552 to 3 decimal places
Answer:
8.513
Step-by-step explanation:
The round off to the number at three decimal places will be 8.513.
What is rounding off the numbers?When a number is rounded off, its value is maintained but is brought closer to the next number, simplifying the number. For entire numbers as well as decimals at different places of hundreds, tens, tenths, etc., it is done.
A number can be rounded off to its lower value if the number after the decimal is between 0 and 4. The number will be rounded off to its higher value if the number after it is between 5 and 9.
The round-off to the number 8.51348434552 to the three decimal places will be 8.513.
