Answer: k = 10
because ∠MYZ is the outer angle of the triangle XYZ
=> ∠MYZ = ∠YZX + ∠YXZ
⇔ 115° = (4k + 5)° + (6k + 10)°
⇔ 115 = 10k + 15
⇔ 10k = 100
⇔ k = 10

Maria is putting up a shelf on a wall in her closet. The figure below shows triangle ABC, which
represents a bracket that will be used to support the shelf. What is the length of the wall? *
Anwer:
14 cm
Step-by-step explanation:
Let's apply the Phytagorean Theorem [tex]a^{2}+b^{2}=c^{2}[/tex]
Since we only have one side and the hypotenuse:
[tex]a^{2}+24^{2}=28^{2}\\a^{2}+576=784\\a^{2}=784-576\\a^{2}= 208\\[/tex]
[tex]a=\sqrt{208}\\a= 14.42\\a= 14 cm[/tex]
The length of the wall is approximately 14.4 units.
What is Pythagoras' theorem?
In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.
Maria is putting up a shelf on a wall in her closet.
The figure below shows triangle ABC, which represents a bracket that will be used to support the shelf.
AC = 24, BC = 28 = hypotenuse, AB = wall
Using the Pythagorean theorem, we can solve for the length of AB (the wall):
AB² = BC² - AC²
AB² = 28² - 24²
AB² = 784 - 576
AB² = 208
AB = sqrt(208)
AB ≈ 14.4
Therefore, the length of the wall is approximately 14.4 units.

Bosian was converting Gallons to Quarts. He said that he had 5 gallons. Bosian said that 1 gallon 5 quarts so 5 gallons is 5 What does Bosian do wrong? How do you correct it?
Answer:
Bosian used the wrong conversion for converting Gallons to Quarts. The correct conversion is: 1 gallon = 4 Quarts and correct solution is: 5 gallon = 20 quarts
Step-by-step explanation:
Bosian Conversion from Gallons to Quarts
He had 5 gallons
He said that 1 gallon = 5 quarts
So, 5 gallons = 5*5 = 25 quarts
Mistake of Bosian:
He used the wrong conversion: i.e, 1 gallon = 5 quarts
The correct conversion is:
1 gallon = 4 quarts
Correct Solution:
1 gallon = 4 quarts
So, 5 gallons = 5*4 = 20 quarts

A board 75 cm long is cut into two parts such that one part is 15 cm more than the other. How long is each part?
Answer:
30 cm, and another is 45 cm.
Step-by-step explanation:
First, we need to subtract 15 from 75, giving us 60. Then, we divide 60 by 2, giving us 30, which is the length of one part. We add 15 back to 30, which gives us 45. One part is 30 cm and the other is 45 cm
Solve for b.
r = (b-5)m
Answer:
b=5m+r/m
Step-by-step explanation:
Let's solve for b.
r=(b−5)(m)
Step 1: Flip the equation.
bm−5m=r
Step 2: Add 5m to both sides.
bm−5m+5m=r+5m
bm=5m+r
Step 3: Divide both sides by m.
bm/m=5m+r/m
b=5m+r/m
Answer:
b=5m+r/m
Answer:
See Explanation
Step-by-step explanation:
[tex]r = (b - 5)m \\ \\ \frac{r}{m} = b - 5 \\ \\ \frac{r}{m} + 5 = b \\ \\ \frac{r + 5m}{m} = b \\ \\ \huge \red{ \boxed{b = \frac{r + 5m}{m} }}[/tex]

Write the slope-intercept form of the equation for the line.
y = 2x – 1
y = – 2x – 1
y = 1/2 x-1
y = 1/2 x+1
Answer:
y = 2x - 1
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASAlgebra I
Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Slope-Intercept Form: y = mx + b
m - slope b - y-interceptStep-by-step explanation:
Step 1: Define
Find points on the graph.
Point (1, 1)
Point (-1, -3)
Step 2: Find slope m
Substitute: [tex]m=\frac{-3-1}{-1-1}[/tex]Subtract: [tex]m=\frac{-4}{-2}[/tex]Divide: [tex]m=2[/tex]Step 3: Find y-intercept b
Given: (0, -1) as y-intercept
Step 4: Write linear equation
y = 2x - 1
The equation y = 2x - 1 is the correct representation of the line in slope-intercept form.
The slope-intercept form of a linear equation is given by y = mx + b, where m represents the slope of the line and b represents the y-intercept.
Among the options provided, the equation y = 2x - 1 is already in the slope-intercept form. In this equation, the slope is 2, which means that for every unit increase in x, y increases by 2. The y-intercept is -1, indicating that the line intersects the y-axis at the point (0, -1).
The equations y = -2x - 1, y = 1/2x - 1, and y = 1/2x + 1 are not in slope-intercept form. In the equation y = -2x - 1, the slope is -2 and the y-intercept is -1. In the equation y = 1/2x - 1, the slope is 1/2 and the y-intercept is -1. Lastly, in the equation y = 1/2x + 1, the slope is 1/2 and the y-intercept is 1.
Therefore, the equation y = 2x - 1 is the correct representation of the line in slope-intercept form.

What are Units ?To measure and compare various things we use one term which is known as a unit. When all of the measuring units are the same, comparison is simple. Depending on their intended usage, different units can be categorised.
For example, for length measurement we use units like:- meter, centimeter, inch, miles.
Given that,
Ralph bought some oranges.
