Harper went into a movie theater and bought 10 bags of popcorn and 6 drinks,
costing a total of $79. Damian went into the same movie theater and bought 3 bags of
popcorn and 5 drinks, costing a total of $36.50. Write a system of equations that
could be used to determine the price of each bag of popcorn and the price of each
drink. Define the variables that you use to write the system.
Answer:
The price of a drink = $4
The price of a bag of popcorn = $5.5
Step-by-step explanation:
Let p represent popcorn and d represent drink
Harper bought 10 bags of popcorn and 6 drinks and paid $79 ➡ 10p + 6d = $79
Damian bought 3 bags of popcorn and 5 drinks and paid $36.50 ➡ 3p + 5d = $36.50
Now multiply first equation by -3 and second equation by 10
-3 × (10p + 6d) = $79 ➡ -30p - 18d = -$237
10 × (3p + 5d) = $36.50 ➡ 30p + 50d = $365
Now add the new equationd
30p + 50d -30p - 18d = $365 - $237 (-30p will eliminate 30p)
32d = $128 divide both sides of the equation by 32
32 ÷ 32d = 32 ÷ $128 ➡ d = 4
If d = 4 that means a drink costs $4 we can use this information to find the price of a bag of popcorn
3p + 5d = $36.50 (replace d with 4)
3p + 4×5 = $36.50
3p + 20 = $36.50
3p = $36.50 - 20
3p = 16.50 divide both sides by 3
p = $5.5
The question asked to set up a system of equations to determine the price of each bag of popcorn and each drink. Using the variables x and y to represent the price of popcorn and drinks respectively, the system of equations based on the information given is 10x + 6y = $79 and 3x + 5y = $36.50.
Explanation:To solve this problem, we need to setup a series of equations based on the information given. Let's say:
x is the price of each bag of popcorny is the price of each drinkAccording to the first scenario with Harper, we get:
10x + 6y = $79
From Damian's shopping, we have:
3x + 5y = $36.50
This gives us the system of equations which can be used to find individual prices of a bag of popcorn and a drink.

3a + 3b is equivalent to 3(a + 2b).
A true
B false
Answer:
B-false
Step-by-step explanation:
It is false because where the 2 is, has to be 3, other wise it won't make sense. Because it will not equal the same thing.
Final answer:
The expression 3a + 3b is not equivalent to 3(a + 2b). The first results in 3a + 3b, while applying the distributive property to the second expression gives 3a + 6b, clearly showing the expressions are different.
Explanation:
The statement 3a + 3b is equivalent to 3(a + 2b) is false. To show this, we can apply the distributive property of multiplication over addition, which states that for any real numbers a, b, and c, a · (b + c) = a·b + a·c. Using this property, we can expand 3(a + 2b) to get 3·a + 3·2b, which simplifies to 3a + 6b. This is not the same as 3a + 3b since 3b is not equal to 6b. Therefore, the expressions are not equivalent.

find the value of two numbers if their sum is 11 and the difference is 3
Answer:
7
4
Step-by-step explanation:
7+4=11
7-4=3
To find the value of two numbers if their sum is 11 and the difference is 3, we can use a system of equations. The two numbers are 7 and 4.
Explanation:To find the value of two numbers if their sum is 11 and the difference is 3, we can use a system of equations.
Let's call the two numbers x and y. We can set up the following equations:
x + y = 11
x - y = 3
Now we can solve this system of equations by adding the two equations together:
(x + y) + (x - y) = 11 + 3
Simplifying, we get:2x = 14
Dividing both sides by 2, we get:x = 7
Now we can substitute this value of x back into one of the original equations to solve for y:7 + y = 11
Subtracting 7 from both sides, we get:y = 4
So, the two numbers are 7 and 4.

brainliest plz
Final answer:
Mikey the monkey ate more bananas than Mick, consuming 5 compared to Mick's 4 bananas.
Explanation:
Let's calculate how many bananas each monkey ate. We'll start with Mick the monkey, who had 10 bananas and ate two fifths of them.
Calculate two fifths of 10 bananas: (2/5) × 10 = 4 bananas.
Mick therefore ate 4 bananas.
Now, let's calculate for Mikey the monkey, who also had 10 bananas and ate half of them.
Calculate half of 10 bananas: (1/2) × 10 = 5 bananas.
Mikey ate 5 bananas.
Mikey the monkey ate more bananas than Mick because 5 is greater than 4.

A card is drawn at random from a pack of 52 playing cards. Given that the card is a diamond, find the probability that the card is a King. Give your answer as a fraction in its simplest form.
================================================
Explanation:
Focus only on the diamond cards. There are 13 of them total. Out of the 13 diamond cards, there is one king of diamonds. So the probability of getting a king, if we know 100% the card is a diamond, is 1/13.
---------------
You can use a slightly longer method through a conditional probability
A = card is a king
B = card is a diamond
P(A and B) = probability of king and diamonds = 1/52
P(A \ B) = probability of event A happens given we know B happens
P(A \ B) = P(A and B)/P(B)
P(A \ B) = (1/52)/(13/52)
P(A \ B) = (1/52) ÷ (13/52)
P(A \ B) = (1/52) * (52/13)
P(A \ B) = 1/13
The probability that the card is a King is 1/13
Probability is the likelihood or chance that an event will occur.
Probability = Expected outcome/Total outcome
Given that a card is drawn at random from a pack of 52 playing cards, the total outcome is 52
If the card is a king, the expected outcome is 4
Pr(selecting a king) = 4/52 = 1/13
Hence the probability that the card is a King is 1/13

What is d,the common difference,in the arithmetic sequence 100,98,96,94,92...?
Answer: he is right the answer is -2
Step-by-step explanation:
The common difference (d) is -2.
In an arithmetic sequence, the common difference (d) is the constant value by which each term differs from the previous term.
To find the common difference in the sequence 100, 98, 96, 94, 92..., we can observe the difference between consecutive terms:
98 - 100 = -2
96 - 98 = -2
94 - 96 = -2
92 - 94 = -2
We see that each term is decreasing by 2. Therefore, the common difference (d) is -2.
What geometric shape best describes the sun? triangular prism cube cylinder sphere
Answer:
A sphere.
Step-by-step explanation:
The sun is a sphere.
The best geometric shape to describe the Sun is a sphere, as it appears as a circular disc in the sky and fits with observational data and theoretical models of its structure and the Earth's orbit around it.
Explanation:When considering the geometric shape that best describes the Sun, we assess its physical appearance and symmetry. The Sun is often depicted in diagrams as having a perfectly round, spherical shape, which aligns with our observations, as it appears as a circular disk in the sky. A sphere is a three-dimensional object where every point on the surface is the same distance from the center, which closely matches the Sun's observed shape. Unlike a triangular prism, cube or cylinder, a sphere has no edges, vertices, or faces, which makes it the best match for the Sun's shape.
Moreover, observations about the Sun, like those represented in figures discussing its structure as well as the Earth's orbit around the Sun, support the description of the Sun as being spherical. The orbit of the Earth itself is very close to a circle, which assumes central body - the Sun - of spherical form to exert a uniform gravitational pull. Additionally, the celestial sphere concept, although now known to be an incorrect model for the universe, also envisions stars, including our Sun, as points on a vast imaginary sphere, once more alluding to the spherical structure of these celestial bodies.

Find the first, fourth, and tenth terms of the arithmetic sequence described by the given rule. A(n)=5+(n-1)(1/6)
Answer:
First term: A(1) = 5
Fourth term: A(4) = 5 1/2
Tenth term: A (10) = 6 1/2
Step-by-step explanation:
Let's find the first, fourth and tenth terms of the arithmetic sequence described by the given rule:
A(n) = 5 + (n-1) (1/6)
First term:
A(1) = 5 + (1-1) (1/6)
A(1) = 5 + (0) (1/6)
A(1) = 5
Fourth term:
A(4) = 5 + (4-1) (1/6)
A(4) = 5 + (3) (1/6)
A(4) = 5 + 3/6 = 5 3/6 = 5 1/2 (simplifying)
Tenth term
A(10) = 5 + (10-1) (1/6)
A(10) = 5 + (9) (1/6)
A (10) = 5 + 9/6 = 6 3/6 = 6 1/2 (simplifying)
