was the maximum number of people that could be helped with one plane of supplies?
Answers
Using a system of equations, it is found that the maximum number of people that could be helped with one plane of supplies is: 40,000.
What is a system of equations?A system of equations is when multiple variables are related, and equations are built to find the values of each variable, according to the relations given in the problem.
For this problem, the variables are given as follows, considering the situation described:
Variable x: number of food kits sent.Variable y: number of medicine kits sent.Each food kit helped 8 people and each medicine kit helped 6 people, hence the total number of people helped is given by:
T = 8x + 6y.
This is because we consider that people were helped by only one of them, never both.
Each plane could carry no more than 80,000 pounds. Each food kit weighed 20 pounds and each medicine kit weighed 10 pounds, hence:
20x + 10y = 80000
2x + y = 8000
y = 8000 - 2x.
The maximum volume is of 6000 cubic feet, hence:
x + y = 6000.
y = 6000 - x.
Equaling both equations:
8000 - 2x = 6000 - x
x = 2000.
y = 6000 - x = 4000.
Then the maximum number of people helped is:
T = 8x + 6y = 8 x 2000 + 6 x 4000 = 40,000.

For a sporting event 6,000 tickets were sold, and the proceeds were $78,000. Tickets for children 16 and younger, were $8, adults were $16, and seniors 60 and older were $12. There were 2 times more adults than children at the sporting event.
What system of equations represents the number of children, c, adults, a, and seniors, s, that attended the sporting event?
Responses
c+a+s=6,000
8c+12a+16s=78,000
2a=c
c+a+s=6,000
8c+16a+12s=78,000
a=2c
c+a+s=6,000
8c+12a+16s=78,000
a=2c
c+a+s=6,000
8c+16a+12s=78,000
2a=c
Answers
Option 2 is the answer.
No. on tickets sold = 6000
Proceedings of the tickets sold = $78,000
Cost of tickets for children = $8
Cost of tickets for adults = $16
Cost of tickets for seniors = $12
2 times more adults were present than the children.
Let the number of children be 'c.'
Let the number of adults be 'a.'
Let the number of seniors be 's.'
Since 2 times more adults were present than the children, we get the equation,
a = 2c
No. of tickets sold will be equal to the total no, of people.
∴ c + a + s = 6000
The proceedings will be equal to the sum of the amounts and number of people who bought tickets with that amount,
∴ 8c + 16a + 12s = $78,000
Thus, we have the three equations,
c + a + s = 6000
8c + 16a + 12s = $78,000
a = 2c
This series of equations are given in option 2 Thus, option 2 is the answer.

Cheers!
1. a = 37
2. 100 = y
Explanation:
First problem:
First: You have to get the variable (a) alone, so you must get rid of the “- 15” and in order to do this you have to do the opposite of subtraction, which is addition. You have to add 15 to 22 as well since both sides of the equal sign have to do the same thing.
a - 15 = 22
+ 15 + 15
Second: There is nothing else to do, the answer is a = 37
a = 37
Second problem:
First: Just like the first problem you must get t the variable (y) alone. Since 17 is being subtracted from the variable you must add 17 to “- 17” and just like last time you must do the same to the other side of the equal sign! So you’ll be adding 17 to 83
83 = y - 17
+ 17 + 17
Second: There is nothing else to do, you’re left with 100 = y
100 = y

The order of some mathematical operations is addressed by the commutative property. We can write the binary operation as a + b = b + a. The associative attribute, on the other hand, deals with the grouping of numbers in an operation. For instance, we could write it as (a + b) + (a + b + c).This law states that no matter how the numbers are arranged, the outcome of multiplying two integers remains the same. So A.B = B.A. Examples include: 1 + 2 + 1 + 2 + 4 + 5 + 4 + 20.using the Commutative Law of Multiplication.

Using linear function concepts, we have that:
For a graph in a 1:1 scale, we can look at two consecutive values, y when x = a and y* when x = a + 1, and subtract y* by y. For a graph in another scale, we also do the same thing, but since the scale is not 1:1, we have to divide the subtraction of y* by y by the scale.What is a linear function?A linear function is modeled by:

Write the equation of the line that is parallel to the given line and passes through the given point
Answers
The slope of parallel lines is the same, which is y = 5x - 12.
Parallel lines have the same slope in two dimensions. If we are aware of a point on the line and the equation of the supplied line, we can construct the equation of a line that is parallel to the given line.
Given: a line or point with a slope of m (x - x1), where m is the slope, and (x1,y1) is a point on the line, we obtain
y - (-1) = m (x - 2), and now the line is parallel to the one that was supplied. The slope is the SAME for parallel lines.
y + 2 = 5 (x - 2)
A line with a slope of y + 2 = 5x - 10 points...
Y = 5x – 12 – 2 – Subtract 2 from both sides.
Hence, the equation of the line that is perpendicular to the provided line and passes through has the form y = 5x – 12.

Find domain of the following functions
Answers
The domain of the function g (x) = (x² - 2 x - 15) / (x² + x - 6) is R - {-3, 2}.
We are given a function:
g (x) = (x² - 2 x - 15) / (x² + x - 6)
We need to find the domain of the function.
We know that a function becomes not defined when the denominator becomes 0.
Put x² + x - 6 = 0
x² + 3 x - 2 x - 6 = 0
x (x + 3) - 2( x + 3) = 0
( x + 3 ) ( x - 2 ) = 0
We get x = - 3 and x = 2.
So, these cannot be the values of x
So, the domain is
Domain = R - {-3, 2}
