Makayla and John are selling cookie dough for a school fundraiser. Customers can buy chocolate chip or gingerbread cookie dough. Makayla sold 8 packages of chocolate chip and 12 packages of gingerbread cookie dough for a total of $364. John sold 1 package of chocolate chip and 4 packages of gingerbread cookie dough for a total of $93. Find the cost each of one package of chocolate chip cookie dough and one package of gingerbread cookie dough.
The cost per package is $---- for chocolate chip and $----- for gingerbread.
Answer:
Step-by-step explanation:
Lets give a letter value for the chocolate chip and gingerbread cookies. Lets let C= Chocolate chip and G= Gingerbread For Makayla we can set her equation as 8c+12g=364
For John we can leave it as c+4g=93
To solve the equation we would have to substitute the second one into the first one to solve for gingerbread. Lets isolate C to make C=(93-4g)
We can do this because we know that C=93-4g so we can replace the C variable in the first equation with C=93-4g
8(93-4g) + 12g = 364
744 - 32g + 12g = 364
-32g + 12g = 364 - 744
-20g = -380
g = -380/-20
So we know that g=19 dollars. So one gingerbread cookie dough is $19
So now we can plug in the answer of g which was 19 then solve for C
c = 93 - 4(19)
c = $17 for the chip dough
Answer:
The cost per package is $17 for chocolate chip and $19 for gingerbread.
Step-by-step explanation:
Define the variables:
Let x = cost of chocolate chip cookie dough (in dollars)Let y = cost of gingerbread cookie dough (in dollars)Given information:
Makayla sold 8 packages of chocolate chip and 12 packages of gingerbread cookie dough for a total of $364. John sold 1 package of chocolate chip and 4 packages of gingerbread cookie dough for a total of $93.Create two equations using the defined variables and the given information:
[tex]\textsf{Equation 1}: \quad 8x+12y=364[/tex]
[tex]\textsf{Equation 2}: \quad x+4y=93[/tex]
Multiply Equation 2 by 3:
[tex]\implies 3 \cdot x + 3 \cdot 4y=3 \cdot 93[/tex]
[tex]\implies 3x+12y=279[/tex]
Subtract from Equation 1 to eliminate the term in y:
[tex]\begin{array}{lrl}& 8x+12y =&364\\- & (3x+12y =&279)\\\cline{1-3} & 5x \phantom{+12y)} =& \:\:85\end{array}[/tex]
Solve for x:
[tex]\implies 5x=85[/tex]
[tex]\implies \dfrac{5x}{5}=\dfrac{85}{5}[/tex]
[tex]\implies x=17[/tex]
Substitute the found value of x into Equation 2 and solve for y:
[tex]\implies x+4y=93[/tex]
[tex]\implies 17+4y=93[/tex]
[tex]\implies 17+4y-17=93-17[/tex]
[tex]\implies 4y=76[/tex]
[tex]\implies \dfrac{4y}{4}=\dfrac{76}{4}[/tex]
[tex]\implies y=19[/tex]
Conclusion
Cost per package of chocolate chip cookie dough = $17.Cost per package of gingerbread cookie dough = $19.Learn more about systems of equations here:

A farmer wanted to estimate how many moles were living on his property, so he marked 24 of them with tags. A few weeks later, the farmer drove around his property and noticed 18 tagged moles out of the 330 moles he counted. To the nearest whole number, what is the best estimate for the mole population?
Answer:
The answer is 70 moles
Step-by-step explanation:
For the farmer,
Total no of Moles = 330
No of marked moles with tags = 24
No of unmarked moles = 330 - 24 = 306
Few weeks later,
No of tagged moles found = 18
No of tagged moles not found,
= marked moles with tags - tagged moles found
= 24 - 18 = 6
Therefore, if for every 24 tagged moles, there are 6 moles found,
288 tagged moles = 24 X 12 (lots) = 288
For moles found = 6 X 12 (lots) = 72
To the nearest whole number,
The best estimate for the mole population would be 70 moles

Two sides of a triangle have lengths 8 and 16. Which expression describes the length of the third side?
greater than 8 and at most 24
at least 8 and at most 24
at least 8 and less than 24
greater than 8 and less than 24
Answer:
Based on the given description above, the correct answer would be the second statement. If two lengths of two sides of a triangle are 9 and 15, therefore, the length of the third side must be greater than or equal to 6 and at most 24. Hope this answer helps.

So, we have
x less than 50 or x greater than 50
When represented as an inequality, we have
x < 50 or x > 50
Using set notation, we have

Step-by-step explanation: I tested some points from the graph into all of the equations (-8,10) (-4,10) (-6,4) and C is the only one that works for all of them. Plus when you are adding inside an absolute value, it means you are moving to the left by whatever number you added, which automatically eliminates A and D. So B and C were the only ones left and I tested the points to see which one is correct.

what is a solutions of x^2-2x+10=0?
Answer:
x = 1± 3i
Step-by-step explanation:
x^2-2x+10=0
We can complete the square to solve by subtracting 10 from each side
x^2-2x+10-10=-10
x^2 -2x = -10
We need to add (2/2) ^2 to each side or 1
x^2 -2x+1 = -10 +1
x^2 -2x+1 = -9
The left side factors into (x- (2/2) ) ^2
(x-1) ^2 = -9
Take the square root of each side
sqrt((x-1) ^2 =± sqrt(-9)
x-1 = ±sqrt(-1) sqrt(3)
Remember the sqrt(-1) = i
x-1 = ± 3i
Add 1 to each side
x-1+1 = 1± 3i
x = 1± 3i

Answer:
Yes
Step-by-step explanation:
Substitute the x value in the ordered pair for the x in the equation, or 2, and the y-value (6) in for y. So, 2 + 6 = 8, and this is true. Then do 3(2) - 6 = 0, which is also true.

Chloe is deciding between two landscaping companies for her place of business. Company A charges $70 per hour and a $150 equipment fee. Company B charges $55 per hour and a $300 equipment fee. Let AA represent the amount Company A would charge for tt hours of landscaping, and let BB represent the amount Company B would charge for tt hours of landscaping. Write an equation for each situation, in terms of t,t, and determine the number hours, t,t, that would make the cost of each company the same.
The equations are AA = 150 + 70t and BB = 300 + 55t.
It is 10 hours which make the cost of each company the same.
Given,
Company A:
Charge for an hour =$ 70
Equipment fee = $ 150
Charge for ' t ' hours = 70 x t = 70t
Total cost = Equipment fee + charge for t hours
AA = 150 + 70t
Company B:
Charge for an hour =$ 55
Equipment fee = $ 300
Charge for 't' hours = 55 x t = 55t
Total cost = Equipment fee + charge for t hours
BB = 300 + 55t
Now, we have to find
BB = AA
300 + 55t = 150 + 70t
300 – 150 = 70t – 55t
150 = 15t
t = 150 / 15
t = 10
That is,
The equations are AA = 150 + 70t and BB = 300 + 55t.
It is 10 hours which make the cost of each company the same.

When you find the volume of a triangle, remember to do this:
Step-by-step explanation:
Multiply the base times the height, then divide by two.
:)
The mistake is in the second triangle and is noticeable at first because the length of the leg is longer than the length of the hypotenuse.
Since this is a 30 60 90 triangle, you can use the properties that apply to them. I'm assuming that the leg with the length of 62ft is the given side. Using the rules, we know that x/2 is 62 (since the properties of a 30 60 90 triangle state that the shortest side is x/2). In order to find the hypotenuse (which is x), we can multiply both sides of the equation x/2 = 62 to get x = 124. To find the second leg, we need to use sqrt(3)*x/2, which when you plug in 124, gives 107.39. Andrea just switched the lengths of the second leg and the hypotenuse on accident.
