Caesar and Brutus are selling apple pie and lemon meringue pies for a school fundraiser. Caesar sold 5 apple pies and 2 lemon meringue pies for a total for $80. Brutus sold 3 apple pies and 6 lemon meringue for a total of $(0. What is the cost of one apple pie and one lemon merigue pie?
Answer:
Cost of one apple pie is $12.50 and cost of one lemon merigue pie is $8.75
Step-by-step explanation:
Let,
x be the cost of each apple pie
y be the cost of each lemon merigue pie
According to given statement;
5x+2y=80 Eqn 1
3x+6y=90 Eqn 2
Multiplying Eqn 1 by 3
3(5x+2y=80)
15x+6y=240 Eqn 3
Subtracting Eqn 2 from Eqn 3
(15x+6y)-(3x+6y)=240-90
15x+6y-3x-6y=150
12x=150
Dividing both sides by 12
[tex]\frac{12x}{12}=\frac{150}{12}\\x=12.50[/tex]
Putting x=12.50 in Eqn 1
5(12.50)+2y=80
62.50+2y=80
2y=80-62.50
2y=17.50
Dividing both sides by 2
[tex]\frac{2y}{2}=\frac{17.50}{2}\\y=8.75[/tex]
Hence,
Cost of one apple pie is $12.50 and cost of one lemon merigue pie is $8.75

Answer:
x =-18
Step-by-step explanation:
5(x + 9) = -45
Divide each side by 5
5/5(x + 9) = -45/5
x+9 = -9
Subtract 9 from each side
x+9-9 = -9 -9
x =-18
Answer:
The correct answer is x = -1.
Step-by-step explanation:
Step 1: 5(x + 9) = -45 <----- This is the original problem.
Step 2: 5(9x) = -45 <----- Add the variable.
Step 3: [tex]\frac{5(9x)}{5} = \frac{-45}{5}[/tex] <----- Divide both sides by 5.
Step 4: 9x = -9 <----- Simplify
Step 5: 9x/9 = -9/9 <----- Divide both sides by 9.
x = -1

If you roll two dices, you can get as results all numbers from 2 to 12. Among these, the prime numbers are 2, 3, 5, 7, 11. The probability you get each of them is: 2: you can get it only as 1+1, so one combination over 36 possibility. Probability: 1/36. 3: you can get it as 1+2 or 2+1, so two combinations over 36 possibility. Probability: 2/36. 5: you can get it as 1+4, 2+3, 3+2, 4+1, so four combinations over 36 possibility. Probability: 4/36. 7: you can get as 1+6, 2+5, 3+4, 4+3, 5+2, 6+1, so six combinations over 36 possibility. Probability: 6/36. 11: you can get it as 5+6 or 6+5 so two combinations over 36 possibility. Probability: 2/36. The total probability of getting a prime number is the sum of the probabilities, which is 15/36. So m=15, n=36 and 10m+n=150+36=186.
I need help solving this for AP calculus.
Step-by-step explanation:
the derivative of the sum of terms in x is the same as the sum of the derivatives of the individual terms.
d/dx × (-4sin(x) + 9x) = d/dx × (-4sin(x)) + d/dx × (9x)
and also : the derivative of a term in x multiplied by a constant c is c × derivative of the term in x.
d/dx × (-4sin(x)) + d/dx × (9x) =
-4 × (d/dx × sin(x)) + 9 × (d/dx × x)
so, what is the derivative of sin(x) ? cos(x)
what is the derivative of x ? 1
so, we have as result :
-4cos(x) + 9

Line f passes through the points
(10, -1) and (-8, 6).
What is the slope of line f?
Answer:
-7/2 or -3.5
Explanation:
The slope is rise over run.
The rise is how much it went up and the run is how much it went right
The line went up 7 units while going -2 units to the right (meaning it went 2 units to the left)
This makes our slope 7/-2 which is the same as -7/2 or -3.5
you order two tacos and a salad. the salad costs $2.50. you pay 6% sales tax and leave a $3 tip. you pay a total of $13.60. how much does one taco cost?
The cost of one taco is $3.75.
We are given cost of salad, the sales tax and tip along with total expenditure. We already know, that sales tax is calculated on the cost of items. Hence, forming the equation accordingly. Let us assumed the cost of one taco be $x. So, the cost of two tacos will be $2x.
The equation will be -
2x + 2.50 + (2x + 2.50)×(6÷100) + 3 = 13.60
2x + 2.50 + (2x + 2.50)×0.06 + 3 = 13.60
Now, solving this equation to find the value of x and hence the cost of one taco.
2x + 2.50 + 0.12x + 0.15 + 3 = 13.60
Performing addition on Left Hand Side
2.12x + 5.65 = 13.60
Shifting 0.18 to Right Hand Side and performing subtraction
2.12x = 13.60 - 5.65
2.12x = 7.95
x = 7.95÷2.12
Performing division
x = 3.75
Thus, the cost of one taco is $3.75.

Which of the choices best describes this arithmetic sequence?
-2, 1,4,7, 10, ...
Answer:
1
Step-by-step explanation:
An arithmetic sequence is a sequence in which each term after the first is found by adding a comstant, called the common difference d, to the previous term. The set of positive odd numbers, 1, 3, 5, 7, ... , is a sequence. The first term, a1, is 1 and each term is 2 greater than the preceding term.
One environmental group did a study of recycling habits in a California community. It found that 75% of the aluminum cans sold in the area were recycled. (Use the normal approximation. Round your answers to four decimal places.)
(a) If 387 cans are sold today, what is the probability that 300 or more will be recycled?
(b) Of the 387 cans sold, what is the probability that between 260 and 300 will be recycled?
Answer:
a
[tex]P( \^ p > 0.775 ) = 0.12798[/tex]
b
[tex]P( 0.6718 < p < 0.775 ) =0.87183[/tex]
Step-by-step explanation:
From the question we are told that
The population proportion is [tex]p = 0.75[/tex]
Considering question a
The sample size is [tex]n = 387[/tex]
Generally the standard deviation of this sampling distribution is
[tex]\sigma = \sqrt{ \frac{p(1 - p)}{ n } }[/tex]
=> [tex]\sigma = \sqrt{ \frac{0.75(1 - 0.75)}{ 387 } }[/tex]
=> [tex]\sigma = 0.022[/tex]
The sample proportion of cans that are recycled is
[tex]\^ p = \frac{ 300}{387 }[/tex]
=> [tex]\^ p = 0.775[/tex]
Generally the probability that 300 or more will be recycled is mathematically represented as
[tex]P( \^ p > 0.775 ) = P( \frac{\^ p - p }{ \sigma } > \frac{0.775 - 0.75 }{ 0.022} )[/tex]
[tex]\frac{\^ p - p }{\sigma } = Z (The \ standardized \ value\ of \ \^ p )[/tex]
[tex]P( \^ p > 0.775 ) = P( Z > 1.136 )[/tex]
From the z table the area under the normal curve to the left corresponding to 1.591 is
[tex]P( Z > 1.136) = 0.12798[/tex]
=> [tex]P( \^ p > 0.775 ) = 0.12798[/tex]
Considering question b
Generally the lower limit of sample proportion of cans that are recycled is
[tex]\^ p_1 = \frac{ 260 }{387 }[/tex]
=> [tex]\^ p_1 = 0.6718[/tex]
Generally the upper limit of sample proportion of cans that are recycled is
[tex]\^ p_2 = \frac{ 300}{387 }[/tex]
=> [tex]\^ p_2 = 0.775[/tex]
Generally probability that between 260 and 300 will be recycled is mathematically represented as
[tex]P( 0.6718 < p < 0.775 ) = P( \frac{0.6718 - 0.75 }{ 0.022}< \frac{\^ p - p }{ \sigma } <\frac{0.775 - 0.75 }{ 0.022} )[/tex]
=> [tex]P( 0.6718 < p < 0.775 ) = P( -3.55 < Z < 1.136 )[/tex]
=> [tex]P( 0.6718 < p < 0.775 ) = P(Z < 1.136 ) - P( Z < -3.55 )[/tex]
From the z table the area under the normal curve to the left corresponding to 1.136 and -3.55 is
[tex]P( Z < -3.55 ) = 0.00019262[/tex]
and
[tex]P(Z < 1.136 ) = 0.87202[/tex]
So
[tex]P( 0.6718 < p < 0.775 ) = 0.87202- 0.00019262[/tex]
=> [tex]P( 0.6718 < p < 0.775 ) =0.87183[/tex]

The algebraic property of "if 12+4x then 4x+12" is: commutative property of addition.
What is the Commutative Property of Addition?The Commutative Property of Addition is an algebraic property that states that the change of arrangement or order of an expression does not change the sum of the expression.
For example, based on the commutative property of addition, a + b = b + a.
In the same vein, if we have 12 + 4x, then 4x + 12, it means that whichever way we choose to order the operation, the sum remains the same.
Therefore, the algebraic property of "if 12+4x then 4x+12" is: commutative property of addition.

Chris and Evan are selling bags of popcorn to raise money for a club at school. Chris started with 10 bags and he sells 4 bags each day. Evan began with 8 bags and sells 2 bags each day. How many days will it take before they both have the same number of bags remaining? A. 2 days B. 4 days C. 1 day D. 6 days
Answer:
C. 1 day
Step-by-step explanation:
Chris:
10 - 4d
Evan:
8 - 2d
How many days will it take before they both have the same number of bags remaining?
Equate both expressions and solve
10 - 4d = 8 - 2d
Collect like terms
10 - 8 = -2d + 4d
2 = 2d
Divide both sides by 2
d = 2/2
= 1
d = 1 day
It will take 1 day before they both have the same number of bags remaining
