At an archery competition, Jamie and Marshall's team tied Shawna and Wyatt's team for the top team score. Team scores are determined by adding the two teams members individual scores. Marshall scores 12 less than Jamie. Shawna scored twice as much as Marshall. Wyatt scored 4 less than Shawna. What was each person's individual score?
Answers
Given:
Jamie and Marshall's team tied Shawna and Wyatt's team for the top team score.
Marshall scores 12 less than Jamie. Shawna scored twice as much as Marshall. Wyatt scored 4 less than Shawna.
To find:
The individual score of each person.
Solution:
Let x be the score of Jamie.
Marshall scores 12 less than Jamie.
Marshall score = x-12
Shawna scored twice as much as Marshall.
Shawna score = 2(x-12)
Wyatt scored 4 less than Shawna.
Wyatt score = 2(x-12)-4
Now,
Score of Jamie and Marshall's team [tex]=x+(x-12)[/tex]
Score of Shawna and Wyatt's team [tex]=2(x-12)+2(x-12)-4[/tex]
Jamie and Marshall's team tied Shawna and Wyatt's team
[tex]x+(x-12)=2(x-12)+2(x-12)-4[/tex]
[tex]x+x-12=2x-24+2x-24-4[/tex]
[tex]2x-12=4x-52[/tex]
Isolate x.
[tex]2x-4x=-52+12[/tex]
[tex]-2x=-40[/tex]
Divide both sides by -2.
[tex]x=\dfrac{-40}{-2}[/tex]
[tex]x=20[/tex]
So, Jamie score = 20
Marshall score = 20-12
= 8
Shawna score = 2(20-12)
= 2(8)
= 16
Wyatt score = 2(20-12)-4
= 2(8)-4
= 16-4
= 12
Therefore, the scores of Jamie, Marshall, Shawna and Wyatt are 20, 8, 16 and 12 respectively.

How many single tickets [blank] couple tickets sold [blank]
20s + 35c = 2845
20s + 35c + 128
Answers
Step-by-step explanation:
Let S be the number of single tickets sold.
Let C be the number of couple tickets sold.
[tex]20s + 35c = 2845[/tex]
[tex]s + c = 128[/tex]
Multiplying the lower system by -20 we get;
[tex]20s + 35c = 2845[/tex]
[tex] - 20s - 20c = - 2560[/tex]
Adding the two systems i get;
[tex]35c - 20c = 2845 - 2560[/tex]
[tex]15c = 285[/tex]
[tex]c = \frac{285}{15} = 19[/tex]
Substituting C=19 in s+c=128,
we get that;
[tex]s + 19 = 128[/tex]
[tex]s = 128 - 19[/tex]
[tex]s = 117[/tex]

E. 12
Step-by-step explanation:
1. p÷q=3. p+q=8 We know that p and q are positive, as dividing by a negative number gives a negative product.
2. 4÷4 does not equal to 3, so neither p nor q can equal 4.
3. As 6÷2=3, p=6 and q=2, or it could be the other way around.
4. Since p=6 and q=2, 6x2=12.
5. pq=12.

A dilation preserves side lengths.
A dilation preserves angle measures.
A dilation preserves the direction that the shape faces.
A dilation is a type of isometric transformation.
The side lengths of a dilated image are proportional to the side lengths of the pre-image.
Answers
Answer:
B, C, E
Step-by-step explanation:
Edg 2021
A dilation preserves angle measures. A dilation preserves the direction that the shape faces. The side lengths of a dilated image are proportional to the side lengths of the pre-image.
Transformation is the movement of a point from its initial location to a new location. Types of transformation are translation, rotation, reflection and dilation.
Dilation is the increase or decrease in the size of a figure by a factor k, hence the side lengths of a dilated image are proportional to the side lengths of the pre-image.
Dilation does not preserve the side lengths but it preserves the angle measures. Dilation also preserves the orientation (i.e. the direction that the shape faces).
Dilation is not an isometric transformation.

Juan writes the expression below to determine the total cost of 1 sandwich and n side dishes. 10 . 50 + 1 . 50 ( n − 1 ) Juan orders a sandwich and the same number of side dishes each of the five days this week. All together, Juan pays $75 for these 5 lunches. Write an equation that can be used to find the number of side dishes Juan orders for lunch this week.
Answers
Answer:
She has n= 4 side dishes.
Total side dishes ordered = 5n = 20
Step-by-step explanation:
The total cost is given by
TC= 10 . 50 + 1 . 50 ( n − 1 )
She orders same 5 lunches for $ 75
$ 75= 5{ 10 . 50 + 1 . 50 ( n − 1 ) }
Or
Cost of 1 lunch would be $ 15
$ 75/5 = { 10 . 50 + 1 . 50 ( n − 1 ) }
or
$ 15 = 10 . 50 + 1 . 50 ( n − 1 )
$ 15-$ 10 . 50 = 1 . 50 ( n − 1 )
$ 4.5/ 1.5= n-1
$ 3= n-1
3+1= n
n= 4
She has n= 4 side dishes.
Total side dishes ordered = 5n = 20
She spent
$ 1.50 ( 4-1) = $ 4.5 each day or $22.5 on side dishes for 5 days.

Line M passes through points (2,-5) and (4, -3). Line N passes through points (-4, -8) and (-6,-6). Are lines M and N perpendicular? Explain.
A. No, the lines are not perpendicular because the product of their slopes equals -1.
B. Yes, the lines are perpendicular because the product of their slopes equals-1.
C. No, their lines are not perpendicular because the product of their slopes does not equal-1.
D. Yes, the lines are perpendicular because the product of their slopes does not equal -1.
Answers
Answer:
Yes, the lines are perpendicular because the product of their slopes equals -1 ⇒ B
Step-by-step explanation:
The product of the slopes of the perpendicular lines is -1
So to prove that the lines are perpendicular let us find their slopes
The rule of the slope is:
[tex]m=\frac{y2-y1}{x2-x1}[/tex] , where (x1, y1) and (x2, y2) are two points on the line
∵ Line M passes through points (2, -5) and (4, -3)
∴ x1 = 2 and x2 = 4
∴ y1 = -5 and y2 = -3
→ By using the rule of the slope above
∴ [tex]m=\frac{-3-(-5)}{4-2}=\frac{-3+5}{2}=\frac{2}{2}[/tex]
∴ The slope of line M is 1
∵ Line N passes through points (-4, -8) and (-6, -6)
∴ x1 = -4 and x2 = -6
∴ y1 = -8 and y2 = -6
→ By using the rule of the slope above
∴ [tex]m=\frac{-6-(-8)}{-6-(-4)}=\frac{-6+8}{-6+4}=\frac{2}{-2}[/tex]
∴ The slope of line N is -1
∵ 1 × -1 = -1
∴ The product of the slopes of lines M and N is -1
∴ Lines M and N are perpendicular
∴ Yes, the lines are perpendicular because the product of their
slopes equals -1.

Train A leaves New York for California at the same time Train B leaves California for New York. They are 2900 miles apart. They both travel at an average speed of 120 mph. A. What is the velocity of train A? B. What is the velocity of train B? C. How long will it take before they meet? Show your work.
Answers
Answer:
(A) 120 mph
(B) -120 mph
(C) 12 hours 5 minutes.
Step-by-step explanation:
Given that,
New York and California are 2900 miles apart,
Both the trains A as well as B travel at an average speed of 120 mph.
Assuming that the path between the starting point in New York and the ending point in California is straight, so the given distance of 2900 miles is actually the shortest distance which is the displacement between the source and destination.
So, the given speed on the straight path is actually the velocity.
Assuming that the velocity is positive in the direction from New York towards California.
(A) So, the velocity of train A (towards California) = 120 mph.
(B) The velocity of train B (towards New York) = -120 mph.
(C) Bothy are moving towards each other, so the relative velocity between them is 120+120=240 mph, and the initial distance between them is 2900 miles.
When they meet, the displacement between them becomes zero, displacement covered= 2900-0=2900 miles.
So, the time, t, taken to cover the displacement 2900 miles with a relative velocity of 240 mph is
[tex]t=\frac{2900}{240}[/tex] [as time= displacement / relative velocity]
[tex]\Rightarrow t=12\frac{1}{12}[/tex] hours
=12 hours 5 minutes.
