Step-by-step explanation:
(1)
[tex]\frac{6}{2}[/tex] = [tex]\frac{4}{p}[/tex] ( cross- multiply )
6p = 8 ( divide both sides by 6 )
p = [tex]\frac{8}{6}[/tex] = [tex]\frac{4}{3}[/tex]
(2)
[tex]\frac{n}{4}[/tex] = [tex]\frac{8}{7}[/tex] ( cross- multiply )
7n = 32 ( divide both sides by 7 )
n = [tex]\frac{32}{7}[/tex]
(3)
[tex]\frac{5}{3}[/tex] = [tex]\frac{x}{4}[/tex] ( cross- multiply )
3x = 20 ( divide both sides by 3 )
x = [tex]\frac{20}{3}[/tex]

1. Frank drives from Adams to Harrison which is a distance of 310 miles. He then travels to Perryton which is 40 miles from Harrison. If it takes him 5 hours to complete the entire trip, how fast is he traveling if he is traveling at a constant rate of speed?
Answer:
70 mph
Step-by-step explanation:
The total number of miles Frank traveled is 350 miles (Adams>Harrison=310, Harrison>Perryton(10)= 350)
350 divided by 5 is 70.
Therefore he was going 70 mph.

write an equation in slope-intercept form for the line passing through each pair of points. (-4,-2) and (2,3)
Answer:
y = 5/6x +4/3
Step-by-step explanation:
The 2-point form of the equation for a line is a useful place to start.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (3 -(-2))/(2 -(-4))(x -(-4)) -2
y = 5/6(x +4) -2
y = 5/6x +20/6 -12/6
y = 5/6x +4/3

Answer:
(-8.5,9)
Step-by-step explanation:
((-8+(-9))/2=-8.5
(7+11)/2=9
(-8.5,9)
Answer:
(-8.5, 9)
Step-by-step explanation:
use midpoint formula
(-8 + -9) ÷2 , (7 + 11) ÷ 2
-17 ÷ 2 , 18 ÷ 2
-8.5 , 9
so the coordinates of the midpoint are (-8.5, 9)

Find MP.
MN=17
NP=3y
MP=5y+9
Answer:
[tex] MP = 29 [/tex]
Step-by-step explanation:
Given:
[tex] MN = 17 [/tex]
[tex] NP = 3y [/tex]
[tex] MP = 5y + 9 [/tex]
[tex] MN + NP = MP [/tex] (segment addition postulate)
[tex] 17 + 3y = 5y + 9 [/tex] (substitution)
[tex] 3y = 5y + 9 - 17 [/tex] (subtracting 17 from each side)
[tex] 3y = 5y + 8 [/tex]
[tex] 3y - 5y = 5y - 8 - 5y [/tex] (Subtracting 5y from both sides)
[tex] -2y = 5y - 8 - 5y [/tex]
[tex] -2y = - 8 [/tex]
[tex] y = 4 [/tex] (dividing both sides by -2)
[tex] MP = 5y + 9 [/tex]
Plug in the value of y
[tex] MP = 5(4) + 9 = 20 + 9 [/tex]
[tex] MP = 29 [/tex]

How many solutions does this equation have? 3s − 8 = 2s
3s - 8 = 2s
First, let's subtract 3s from both sides
-8 = -s
Divide both sides by -1
8 = s
You have one solution which is s = 8
There is only a solution for the given equation 3s − 8 = 2s, s=8.
What is the equation?A mathematical equation is a claim that two expressions, which may contain variables or numbers, are equal. Equations are essential questions, and the main motivations for the development of mathematics have been efforts to methodically find answers to these questions.
It is given that the equation is,3s − 8 = 2s.
In order to find the value of s we have to simplify the given equations by applying the arithmetic operations.
3s - 8 = 2s
3s-2s= +8
s=8
Thus, the number of the solution for the given equation will be 1.

How to write a mixed number in science notation [tex]45\frac{3}{8}[/tex]
Answer:
[tex]4.5375*10^1[/tex]
Step-by-step explanation:
The long division for 3/8 results in getting 0.375, so 45 3/8 is 45.375.
From here, the only thing you can really do is divide it by 10 to get
4.5375 and since you can't divide further, the answer would be
4.5375 * 10^1

: Consider the distance from the school to the coffee shop and the
distance from the library to the coffee shop. Draw their respective
line segments in the above graph. If the school is relocated in a
way that it is collinear to the coffee shop and the library, and the
distance to the coffee shop is preserved, then the point
representing the school will partition the line segment from the
coffee shop to the library in a x: y ratio. What are the values of x
and y?
Answer:
x = 7 and y = 1
Step-by-step explanation:
Coordinates of Coffee shop = (12, 16)
Coordinates of Library = (16, 8)
School has been shifted to the new position so that distance of school is preserved from the coffee shop.
Coordinates of the new position of school = (15, 10)
Ratio in which distance between coffee shop and library is divided by the location of school is x : y.
If a segment having extreme ends [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is divided into two parts by point (x, y) in the ratio of m : n,
x = [tex]\frac{mx_2+nx_1}{m+n}[/tex]
y = [tex]\frac{my_2+ny_1}{m+n}[/tex]
From the points given in the picture,
15 = [tex]\frac{16x+8y}{x+y}[/tex]
15x + 15y = 16x + 8y
15y - 8y = 16x - 15x
7y = x
[tex]\frac{x}{y}=\frac{7}{1}[/tex]
Therefore, x = 7 and y = 1 will be the answer.
