Answer: See explanation
Step-by-step explanation:
Your question isn't complete and I couldn't get the exact question online but let's reframe it and solve it.
The restaurant manager wants to find how much they are spending for pies and cakes. Last week they payed 204$ for 12 pies and 8 cakes. This week, they paid $129 for 5 pies and 7 cakes.
Let's say the cost of pies is x
Let's say the cost of cake is y.
We'll then use the information given to make an equation which will be:
Last week they payed 204$ for 12 pies and 8 cakes. This will be:
12x + 8y = 204........ i
This week, they paid $129 or 5 pies and 7 cakes. This will be:
5x + 7y = 129 ........... ii
Therefore,
12x + 8y = 204........ i
5x + 7y = 129 .......... ii
Multiply equation i by 5
Multiply equation ii by 12
60x + 40y = 1020 ....... iii
60x + 84y = 1548 ........ iv
Subtract iii from iv.
44y = 528
y = 528/44
y = 12
The cost of cake is $12.
From equation i,
12x + 8y = 204
12x + 8(12) = 204
12x + 96 = 204
12x = 204 - 96
12x = 108
x = 108/12
x = 9
The cost of pies is $9.

Answer:
B
Step-by-step explanation:
y = 3x + 4
plug in (-2, -2)
-2 = -6 +4
-2 = -2
y = 6x + 10
plug in (-2, -2)
-2 = -12 + 10
-2 = -2
Answer:
B
Step-by-step explanation:
Given the 2 equations
y = 3x + 4 → (1)
y = 6x + 10 → (2)
Substitute y = 6x + 10 into (1)
6x + 10 = 3x + 4 ( subtract 3x from both sides )
3x + 10 = 4 ( subtract 10 from both sides )
3x = - 6 ( divide both sides by 3 )
x = - 2
substitute x = - 2 into either of the 2 equations and evaluate for y
Substituting into (1)
y = 3(- 2) + 4 = - 6 + 4 = - 2
solution is (- 2, - 2 ) → B

12 + 20 = 32
A coke can and a monster can are each in the shape of a right circular cylinder. The cans have the same radius but the height of the monster can is 2 times the height of the coke can. What is the ratio of the volume of the coke can to the volume of the monster can
Answer:
1 : 8
Step-by-step explanation:
Given the height of 2 similar cylinders = a : b , then
ratio of volumes = a³ : b³
Here the ratio of heights = 1 : 2
ratio of volumes = 1³ : 2³ = 1 : 8

Find the slope of the line that passes through the points (-6,6)and(4,-2).
Answer:
=-4/5
Step-by-step explanation:
To find the slope, we can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( -2 -6)/(4 - -6)
= (-2-6)/( 4+6)
= -8/10
=-4/5

a car uses 32 L of gas to travel 450 KM. how many liters would be required to drive 800 km (to the nearest tenth)?
Answer: 56.88 L
Explanation:
Let L represents number of liters
A Car uses 32 L of gas to travel 450 km.
Write a proportion for the problem using rates.
450/32 = 800/L
Cross product is 450*L = 800*32
450L = 25600
Divide each side by 450.
450L/450 = 25600/450
L = 56.88

Does the location of the first aid station actually fall in the middle of the park? Provide mathematical calculations to support your answer.
Answer:
The first aid station is at the middle of the park.
Step-by-step explanation:
Given
[tex](0,0) \to[/tex] Origin of Fun
[tex](-7, 6) \to[/tex] Quadratics in Motion
[tex](-2, 14) \to[/tex]Towers of Trigonometry
[tex](5,8) \to[/tex] The Food Equation
[tex](-1,7)\to[/tex] First aid station
Solving (a): Plot the above points
See attachment for plot
Solving (b): Determine if the first aid station is at the center of the park
From the plot, we have the opposite points to be:
(1) [tex](0,0)[/tex] and [tex](-2, 14)[/tex]
(2) [tex](5,8)[/tex] and [tex](-7, 6)[/tex]
Calculate midpoint using:
[tex]M = \frac{1}{2}(x_1 + x_2, y_1 + y_2)[/tex]
For (1):
[tex]M = \frac{1}{2}(0 -2, 0 + 14)[/tex]
[tex]M = \frac{1}{2}(-2,14)[/tex]
[tex]M = (-1,7)[/tex]
For (2):
[tex]M = \frac{1}{2}(5 -7, 8 + 6)[/tex]
[tex]M = \frac{1}{2}(-2,14)[/tex]
[tex]M = (-1,7)[/tex]
From the above computation, we have midpoint to be:
[tex]M = (-1,7)[/tex]
Given that:
[tex](-1,7)\to[/tex] First aid station
We can conclude that the first aid station is at the middle of the park.
