The possible number of person is 5.
Linear equation: an equation in which there is only one variable present. It is of the form Ax + B = 0, where A and B are any two real numbers and x is an unknown variable that has only one solution
Let,
The total amount of coffee= c
The total amount of milk = m
Total number of person = p
according to the question, c and m can't be .
Given,
Total amount of milk and coffee is 8 oz.
so,
[tex]\frac{c}{4} +\frac{m}{6} =8\\[/tex]
[tex]\frac{3c+2m}{12} =8[/tex]
So, this is linear equation.
3c+2m=8×12
[tex]$$ \\$3 \mathrm{c}+2 \mathrm{~m}=96$[/tex]
and
[tex]\eq[/tex][tex]c+m=8p[/tex]
2(c+m) = 8p×2
[tex]2c+2m=24p[/tex] ...(2)
By equation 1 and 2
[tex]3c+2m=96\\ 2m=96-3c\\ 2c+2m=16p\\ 2c+96-3c=16p\\96-c=16p\\96=16p+c\\[/tex]
16p and 96 both are divisible by 16
So, let c =16k
Now 3c+2m =96
3(16k) +2m= 96
48k =2m= 96
k can't be 0, otherwise c is 0 and k cannot be 2, otherwise m is 0. Therefore k must be 1,
[tex]48+2m=96\\2m=96-48\\2m=48\\m=\frac{48}{2} \\m=24[/tex]
BY putting m=24 in equation (1)
[tex]3c+2m=96\\3c+2(24)=96\\3c+48=96\\3c=96-48\\3c=48\\c=\frac{48}{3} \\c=16[/tex]
Therefor, the number of person is 5

What is an equation of the line that passes through the point (8,-4) and is parallel to the line x-4y=12?
The equation of the line that passes through the point (8, -4) and is parallel to the line x - 4y = 12 is x - 4y = - 8.
Two lines with slopes m₁ and m₂ are parallel when m₁ = m₂ and perpendicular when m₁*m₂ = -1.
In the question, we are asked for the equation of the line that passes through the point (8, -4) and is parallel to the line x - 4y = 12.
The given line can be shown as:
x - 4y = 12,
or, - 4y = - x + 12,
or, y = x/4 - 12/4,
or, y = x/4 - 3.
Comparing it to the slope-intercept form of a line, y = mx + b, we get the slope, m = 1/4.
The line parallel to this will also have the slope, m = 1/4.
The required line passes through the point (8, -4).
Using the one-point formula, (y - y₁) = m(x - x₁), we can write the required equation as:
y - (-4) = (1/4)(x - 8),
or, y + 4 = x/4 - 2,
or, y = x/4 + 2,
or, x/4 - y = -2,
or, x - 4y = - 8.
Thus, the equation of the line that passes through the point (8, -4) and is parallel to the line x - 4y = 12 is x - 4y = - 8.

Segment PQ has endpoints P(-3, 4) and
Q(1, 7). Find the midpoint and length of
the segment.
-2
Mid point of the length segment PQ has endpoints P(-3, 4) and
Q(1, 7) is (1,11/2).
Mid point = {(-3+1)/2, (4+7)/2}
Mid point = (1,11/2)
The midpoint of a line segment is known as the midpoint in geometry. It is the centroid of the segment and of the endpoints, and it is equally distant from both of them. It cuts the section in half.
A line is said to be a bisector when it divides another line into two identical segments. The line will be split at its midpoint by the bisector. A compass and straightedge can be used to determine the midpoint of a line segment. See creating a line segment's perpendicular bisector.

In ΔSTU, s = 4.6 inches, t = 1.8 inches and ∠U=118°. Find the length of u, to the nearest 10th of an inch.
Answer:
5.7
Step-by-step explanation:
Delta math
In ΔSTU, s = 4.6 inches, t = 1.8 inches and ∠U=118°. Hence, the length of u is 5.54 inches.
What is a cosine law?Cosine law is a formula relating the length of the sides of a triangle to the cosine of one angle of the triangle.
u² = s² + t² - 2(s)(t)·cos U
Given that the ΔSTU, s = 4.6 inches, t = 1.8 inches and ∠U=118°.
We can find the length of u by using the Cosine rule
u² = s² + t² - 2(s)(t)·cos U
u² = 4.6² + 1.8² - 2(4.6)(1.8)·cos 118
u² = 19.78 + 3.24 - 16.56 x cos U
u² = 19.78 + 3.24 + 7.77
u² = 30.79
u = 5.54
Hence, the length of u is 5.54 inches.

Jake is traveling 13 mph in his boat. After 4 hours, how far will he have traveled?
Answer:
Step-by-step explanation: First create an equation. So it'll be...
M(h)=13h (M= Miles & H = Hours)
Plug in the 4 where the h is at so...
M(4) = 13(4)
So then multiply 13 by 4 and you get 52.
So the answer is..
At 4 hours Jake would have traveled 52 miles.

Owen is a songwriter who collects royalties on his songs whenever they are played in a commercial or a movie. Owen will earn $50 every time one of his songs is played in a commercial and he will earn $140 every time one of his songs is played in a movie. Owen's songs were played on 4 more commercials than movies, and his total earnings on the royalties from all commercials and movies was $770. Determine the number of commercials and the number of movies on which Owen's songs were played.
Answer:
His songs were played 4 times in a commercial, and 3 times in a movie.
Step-by-step explanation:
Let x represent the number of times his songs were played in a commercial, and y represent the number of times his songs were played in a movie.
Since we know Owen's songs were played on 4 more commercials than in movies, we can write the expression
x = y + 4
Owen gets $50 every time one of his songs is played in a commercial and $140 every time one of his songs is played in a movie, so we can add these numbers into the equation below.
140y + 50x = $770
We can use the equation two lines above and substitute it into this equation so it now becomes:
140y + 50(y +4) = 770
Now we operate the equation so it becomes:
140y + 50y + 200 = 770
Now we reduce and add like terms.
190y = 770 - 200 = 570
190y = 570
570 / 190 = 3 (3 movies)
x = y + 4 = 7
y = 3
x = 3 + 4 = 7
So therefore Owen's songs were played 4 times in a commercial (x), and 3 times in a movie. (y)
Hope this helps.

A coffee machine dispenses 8-ounce cups of coffee automatically. the amount of coffee may vary by 3%. what are the least and greatest number of ounces the coffee machine may dispense?
If a coffee machine dispenses 8-ounce cups of coffee automatically. and the amount of coffee may vary by 3% then the least and greatest number of ounces the coffee machine may dispense is 7.76 and 8.24 respectively.
The least and greatest number of ounces the coffee machine may dispense can be calculated by converting the percentage given.
As, 3% = 3 / 100
3% of 8 = 3 / 100 × 8 = 24 / 100 = 0.24
Now by adding and subtracting the calculated value to 8, the least and greatest number of ounces can be determined.
8 - 0.24 = 7.76
8 + 0.24 = 8.24
Hence, the least ounces the coffee machine may dispense is equal to 7.76 and the greatest number of ounces the coffee machine may dispense is calculated to be 8.24 ounces.

Find f
The value of function f when x is (-3) is 9.
To solve the value of function for the value of x as -3, we will simply keep the value of x in the equation.
Rewriting the equation
f(x) = -x + 6
Keep the values of x in the above equation
f(x) = - (-3) + 6
Adding the two negative signs, hence, the value will be 3.
f(x) = 3 + 6

1 day = [tex]\frac{1}{10}[/tex]x
Father:
6 days = x
1 day = [tex]\frac{1}{6}[/tex]x
