Can you guys create your own system of equations word problem, define the variable, write an equation, then solve it and make a sentence explanation on why you did what you chose
Thanks will give brainliest
Answers
Answer:
Using a system of equations, however, allows me to use two different variables for the two different unknowns.
number of adults: a
number of children: c
With these variables, I can create equations for the totals they've given me:
total number: a + c = 2200
total income: 4a + 1.5c = 5050
Now I can solve the system for the number of adults and the number of children. I will solve the first equation for one of the variables, and then substitute the result into the other equation:
a = 2200 – c
4(2200 – c) + 1.5c = 5050
8800 – 4c + 1.5c = 5050
8800 – 2.5c = 5050
–2.5c = –3750
c = 1500
Now I can back-solve for the value of the other variable:
a = 2200 – (1500) = 700
I have values for my two variables. I can look back at my definitions for the variables to interpret these values. To answer the original question, there were:
1500 children and 700 adults.
Final answer:
A word problem involving two people and their apples, where Alice has twice as many apples as Bob. The variables are defined, the equation is written, and the solution is found.
Explanation:
Word Problem:
Alice has twice as many apples as Bob. Together, they have 15 apples. Define the variable 'x' as the number of apples Bob has.
Equation:
Alice's apples: 2x
Bob's apples: x
2x + x = 15
Solution:
Combining like terms: 3x = 15
Dividing both sides by 3: x = 5
Sentence Explanation:
We defined the variable 'x' as the number of apples Bob has. Since Alice has twice as many apples, we expressed her number of apples as 2x. The total number of apples they have together is 15, so we created an equation by summing up both Alice's and Bob's apples. By solving for 'x', we found that Bob has 5 apples.

Line segment BD is a diameter of circle E.
Circle E is inscribed with triangle B C D. LIne segment B D is a diameter. Line segments D C and C B are secants. Angle D B C is 51 degrees.
What is the measure of arc B C?
39°
78°
102°
129°
Answers
Answer:
78 degrees
Step-by-step explanation:
Mainly because the measure of the arcs intercepted by the interior angles equals 2 times those interior angles.
so arc DC = 2 * angle DBC = 2 * 51 degrees = 102 degrees.
We also see that because BD is a diameter the angle BCD that intercepts it is 90 degrees because half-circle arc BD = 2 * angle BCD
180 degrees = 2 * angle BCD
also we want arc BC.
we know that the total circle is the sum of all 3 arcs.
arc BC + (half-circle) arc BD + arc DC = 360 degrees
arc BC + 180 + 102 = 360 degrees.
arc BC = 360 - 180 - 102 = 78 degrees

Deanna gets 3 problems incorrect on her math quiz and scores 85%. How many questions were on the quiz?
Answers
Answer:
There were 20 questions on the quiz
Step-by-step explanation:
In this question, we are concerned with knowing the number of questions on a quiz, given that Deana had a certain percentage after scoring an amount of marks.
We proceed as follows;
Let the number of questions on the quiz be X.
Now, she got 85% by making 3 incorrect choices. This means the percentage of questions she got incorrectly would be 100-85 = 15%
what we are saying is that it is just 15% of her questions that were wrong.
This mathematically;
15% of x = 3
15/100 * x = 3
15x = 3 * 100
15x = 300
x = 300/15
x = 20

[tex]180(n - 2) \\ 180(6 - 2) \\ 180 \times 4 \\ = 720[/tex]
720 is the sum of interior angles. so to find the value of an angle you have to divide 720 by the number of angles.
[tex] \frac{720}{6} = 120 \: \: degrees[/tex]
we know that,
interior angle + exterior angle = 180 degrees

Sunita creates a scale model of an aeroplane. The scale of the model is 5 cm to 13 m. Sunita's model has a wingspan of 24 cm. What is the wingspan of the real aeroplane?
Answers
To find the wingspan of the real aeroplane, we use the scale of 5 cm to 13 m and set up a proportion comparing the model's wingspan of 24 cm with the real wingspan, which results in a real wingspan of 62.4 m.
Sunita's scale model of an aeroplane has a wingspan of 24 cm, and the scale used is 5 cm to 13 m. To find the wingspan of the real aeroplane, we set up a proportion where 5 cm on the model represents 13 m in reality. The ratio would be:
Model scale: 5 cm
Real scale: 13 m = 1300 cm (since 1 m = 100 cm)
Now we find the corresponding real-life measurement for the 24 cm wingspan on the model:
(5 cm / 1300 cm) = (24 cm / Wingspan in cm)
To solve for the real wingspan, we cross-multiply and divide:
5 cm * Wingspan in cm = 1300 cm * 24 cm
Wingspan in cm = (1300 cm * 24 cm) / 5 cm
Wingspan in cm = 31,200 cm / 5 cm
Wingspan in cm = 6,240 cm
Converting back to meters (divide by 100 since 1 m = 100 cm):
Wingspan in m = 6,240 cm / 100 = 62.4 m

April shoots an arrow upward at a speed of 80 feet per second from a platform 25 feet high. The pathway of the

90 feet
140 feet
125 feet
80 feet
Answers
Answer:
The maximum height of the arrow is 125 feet.
Step-by-step explanation:
The pathway of the arrow can be represented by the equation,
[tex]h = -16t^2 +80t + 25[/tex] .....(1)
Where h is height in in feet and t is time in seconds.
It is required to find the maximum height of the arrow. For maximum height, [tex]\dfrac{dh}{dt}=0[/tex].
So,
[tex]\dfrac{d(-16t^2 +80t + 25)}{dt}=0\\\\-32t+80=0\\\\t=\dfrac{80}{32}\\\\t=2.5\ s[/tex]
Put t = 2.5 s in equation (1). So,
[tex]h = -16(2.5)^2 +80(2.5) + 25\\\\h=125\ \text{feet}[/tex]
So, the maximum height of the arrow is 125 feet.
