The number of dark chocolate AJ sold is 75
What is Simultaneous equation?Simultaneous equations are two or more algebraic equations that share variables e.g. m and d . They are called simultaneous equations because the equations are solved at the same time.
If the number of Milk chocolate candy is m and the number of dark chocolate candy is d, then
m+d= 200 equation 1
3m+4d= 675 equation 2
to eliminate m we multiply both equations by 3
3m+3d= 600 equation 3
3m+ 4d=675 equation 4
subtract equation 3 from 4
d = 675-600
d= 75
Therefore the number of dark chocolate candy AJ sold is 75.

Answer:
C: adding on the right and subtracting on the left; n = 4S: dividing on the left and subtracting on the right; y = 2J: multiplying on the left and dividing on the right; b = 512Step-by-step explanation:
You want the solutions to three equations, and the error in the work shown.
Cullen: -6n +22 = -4n +14Seraphina: 8.4y -6.8 = -3.2y +16.4Jasper: 7/8b -32 = 3/4b +32CullenThe correct solution is ...
[tex]-6n+22=-4n+14\\\\22=2n+14\qquad\text{add $6n$}\\\\8=2n\qquad\text{subtract 14}\\\\\boxed{4=n}[/tex]
Cullen's error was adding 4n to one side, and subtracting 4n from the other side of the equation. (The same operation must be done to both sides.)
SeraphinaThe correct solution is ...
[tex]8.4y -6.8 = -3.2y +16.4\\\\11.6y-6.8=16.4\qquad\text{add $3.2y$}\\\\11.6y=23.2\qquad\text{add 6.8}\\\\\boxed{y=2}[/tex]
Seraphina's error was dividing one side of the equation by 11.6 and subtracting 11.6 from the other side. (The same operation must be done to both sides.)
JasperThe correct solution is ...
[tex]\dfrac{7}{8}b -32 = \dfrac{3}{4}b +32\\\\\dfrac{1}{8}b-32=32\qquad\text{subtract $\dfrac{3}{4}b$}\\\\\dfrac{1}{8}b=64\qquad\text{add 32}\\\\\boxed{b=512}\qquad\text{multiply by 8}[/tex]
Jasper's error was multiplying one side of the equation by 8 and dividing the other side by 8. (The same operation must be done to both sides.)
Name two sets of alternate interior angles.
Answer:
∠ a & ∠ d
∠ b & ∠
Answer:
∠ A and ∠ D
∠ B and ∠ E
Step-by-step explanation:
Write the statement "the sum of a number and 10.7 is at most −3.2" as an inequality.
−3.2 + b > 10.7
−3.2 + b < 10.7
b + 10.7 ≥ −3.2
b + 10.7 ≤ −3.2
The inequality that represents the condition will be b + 10.7 ≥ −3.2. Then the correct option is C.
What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
Let the number be 'b'. Then the statement "the sum of a number and 10.7 is at most −3.2" is written in mathematical form. Then we have
b + 10.7 ≥ −3.2
Thus, the inequality that represents the condition will be b + 10.7 ≥ −3.2. Then the correct option is C.

Which relation is a function?
A function is a relation where each conceivable input value results in exactly one potential output value. The phrase "the output is a function of the input" frequently used.
Explain about the function?An expression, rule, or law in mathematics that specifies the relationship between an independent variable and a dependent variable (the dependent variable). In mathematics and the sciences, functions are fundamental for constructing physical relationships.
An example of a rule is a function, which produces one output for a single input. Alex Federspiel is the picture's author. Y=X2 is an illustration of this. You only get one output for y if you enter anything for x. The fact that x is the input value leads us to say that y is a function of x.

Please reply to the prompt and respond to two other students posts. You will earn 10 points for your initial response and 5 points for each reply. Students

How to respond to other posts:
• In one response, guess which set of variables represent the correlation.
. In the second response, describe how you could alter one of their causal relationships so it instead describes a borrelation.
However, a correlation between two variables does not always imply that a change in one variable is the reason for a change in the values of the other. There is a causal link between the two occurrences, which means that causation shows that one event is the outcome of the occurrence of the other event.
Causal relationships between variables may consist of direct and indirect effects. Direct causal effects are effects that go directly from one variable to another. Indirect effects occur when the relationship between two variables is mediated by one or more variables.
Direct and indirect effects may make up causal connections between variables. Effects that flow directly from one variable to another are referred to as direct causal effects. When one or more factors mediate the link between two variables, indirect effects result.

What is probability ?
The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a proposition is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
The probability that it will rain tomorrow is 0.2

Chad is decorating a rectangular ballroom ceiling with decorative lights. Beginning in a corner, Chad strings the lights along the length of the ceiling, a distance of 55 feet. Next, Chad strings the lights along the width of the ceiling, a distance of 48 feet. Then Chad strings the lights straight back to the original corner. At this point, how many feet of lights has Chad used?
If necessary, round your answer to the nearest tenth.
feet
At the given point, Chad has used 176 feet of light
How to determine the number of feet of light?From the question, we have the following parameters that can be used in our computation:
Length = 55 feet
Width = 48 feet
We start by calculating the distance from the end of the width till the beginning of the length
This is represented by the following Pythagoras theorem
Distance = √(Length² + Width²)
So, we have
Distance = √(55² + 48²)
Evaluate
Distance = 73
The number of feet is then calculated as
Feet = Length + width + distance
So, we have
Feet = 55 + 48 + 73
Evaluate
Feet = 176
Hence, the total distance is 176 feet

Given that, on a recent survey, students were asked if they like to fly and if they can drive.
What is the relative frequency?Relative frequency can be defined as the number of times an event occurs divided by the total number of events occurring in a given scenario.
From the table
Likes to fly
Row totals = Can drive + Cannot drive
0.32+Cannot drive =0.70

Can drive:
Column totals=Likes to fly + Do not likes to fly
0.32 + Do not likes to fly=0.45
Do not likes to fly=0.13
Cannot drive:
Column totals=Likes to fly + Do not likes to fly
0.38 + Do not likes to fly=0.55
Do not likes to fly=0.55-0.38

The amount of time Jim spent on the bicycle is 6.5 hours.
What is distance?The complete movement of an object, regardless of direction, is referred to as distance. The amount of ground a thing travels from its starting point to its destination is also referred to as distance.
Given:
Total distance, d = 255 miles,
Total time, t = 7 hours,
The speed of walking, s = 3 miles / hour,
The speed of riding bicycle, S = 39 miles/hour,
Calculate the time spent on the bicycle as shown below,
Total time = Time on bicycle + Time walking
7 = Distance on bicycle/speed + Distance of walking / speed
7 = b / 39 + w / 3

What are trigonometric ratios?Trigonometric ratios are the ratios of sides of a right-angle triangle. The most common trigonometric ratios are sine, cosine, and tangent.
2tan^2∅ + tan∅ = 0
let k = tan∅
so that we have
2k^2 +k = 0
factorizing,
k( 2k + 1) = 0
Therefore,
k = 0, or 2k + 1 = 0
2k = -1
k = -1/2
so k = 0 or k = -1/2
recall that tan∅ = k
which means
tan∅ = 0 or tan∅ = - 1/2
∅ = arc(tan) 0 or arc(tan) -1/2
∅ = 0° 0r -25.6°
but tan ∅ = -1/2 at 90° to 180° and 270° to 360°
∅ = 0°, (180 - 25.55°), (360 - 25.55°)
