Clark and his friends bought strawberry wafers for $2 per packet and chocolate wafers for $3 per packet at a carnival. They spent a total of $30 to buy a total of 14 packets of wafers of the two varieties.
Part A: Write a system of equations that can be solved to find the number of packets of strawberry wafers and the number of packets of chocolate wafers that Clark and his friends bought at the carnival. Make sure you say what each variable means! (Which one is which wafer type?)
Part B: How many packets of chocolate wafers and strawberry wafers did they buy? Explain how you got the answer and why you selected a particular method to get the answer.
Answer:
Step-by-step explanation:
A. S=strawberry, C=chocolate
S+C=14 equation 1
2s+3c=30 equation 2
B. -2(s+c)=-2(14) multiply equation 1 by -2 to use elimination method
-2s+-2c=-28 modified Equation 1
2s+ 3c=30. Equation 2
C=2 add above two equations.
solve for s
s+c=14
s+2=14
s=12
Used elimination method since it was easier to add the two equations.
check answer by inputting s,c values in either equation.
2s+3c=30
2(12)+3(2)=30
24+6=30
30=30

Answer:
2s+3c=30s+c=142 chocolate12 strawberryStep-by-step explanation:
Part A:
I like to use variable names that remind me what they stand for. Here, we can use s and c for the numbers of strawberry and chocolate packets, respectively. The two equations we can write based on the problem statement are ...
2s + 3c = 30 . . . . . . . the total cost of the purchase
s + c = 14 . . . . . . . . . . the number of items purchased
__
Part B:
Ordinarily, I would use one equation for the problem. That equation can be arrived at by substituting for s using the second equation. We choose to substitute for s so the only remaining variable is the one representing the highest-value contributor to the total cost.
s = 14 -c
2(14 -c) +3c = 30 . . . . substitute for s
28 +c = 30 . . . . . . . . . simplify (notice the coefficient of c is positive)
c = 2 . . . . . . . . . . . subtract 28
s = 14 -2 = 12 . . . . find s using the above equation
They bought 2 packets of chocolate and 12 packets of strawberry wafers.
__
Explanation of choices
When the total purchase is n items and x of them are of one kind, then n-x is the number of the other kind. You don't need to write a second equation to figure that out. Hence the problem can be described by a single equation, such as the one highlighted above. Doing this lets you skip a variable definition and a couple of solution steps you don't really need.
The choice of variable as being the high-cost item ensures that its coefficient in the equation will be positive. Fewer errors are made when arithmetic is done with positive numbers. Again, recognizing that early on saves headaches down the line.
Getting to a generic solution
Note that the number we subtract (28) is the "would be" cost of all of the items purchased being the lowest-cost item (14 strawberry packets). This recognition can let you do the entire problem in your head. The difference between the actual cost and the "would be" cost is the result of replacing some number of the lowest-cost items with the higher-cost ones. The difference between total costs is divided by the difference in cost per item to find the number of the higher-cost item. That is the answer to all problems of this type. (30 -14(2))/(3-2) = 2 = the number of $3 packets.
is 0.27 greater than 0.3 ?
Answer:
No
Step-by-step explanation:
here's a little trick, add a zero to make both numbers the same.
it's doesn't change the value.
so .27 and .3 become .27 and .30
and .30 is greater
If JK= 2x, KL=8, and JL= 4x, what is JK?
(On a line segment)
J 2x K 8 L
|—————————-|————————-|
4x
^_____________|_____________^
Answer:
JK = 8
Step-by-step explanation:
As JK + KL = JL.
2x + 8 = 4x
–2x –2x
8 = 2x
÷2 ÷2
4 = x.
x = 4.
JK = 2x.
x = 4 → JK = 2x → JK = 2(4) → JK = 8.
A trunk measures 48 inches long, 22 ½ feet wide, and 32 inches high. What is the volume of the box? Answer without units
Answer:
Volume of trunk = 4,14,720 inches³
Step-by-step explanation:
Find:
Length of trunk = 48 inches
Width of trunk = 22 ½ feet = 45 / 2 = 22.5 feet
Height of trunk = 32 inches
Find:
Volume of trunk
Computation:
1 feet = 12 inch
Width of trunk = 22.5 feet
Width of trunk = 22.5 x 12
Width of trunk = 270 inches
Volume of trunk = Length x Width x Height
Volume of trunk = 48 x 270 x 32
Volume of trunk = 4,14,720 inches³

Find the value of x, y, and z.
9514 1404 393
Answer:
x = 59°y = 40°z = 81°Step-by-step explanation:
The marked external angle at B is "corresponding" to the internal angle BAD, so is the same measure. This means ...
z° +40° = 121°
z° = 81°
__
Adjacent angles of a parallelogram are supplementary, so ...
∠CDA +∠BAD = 180°
x° + 121° = 180°
x° = 180° -121°
x° = 59°
__
Alternate interior angles are congruent, so ...
y° = 40°

If 1/3 of 33 bakers can make 89 pretzels in 2 1/2 hours, then how many pretzels can 5 3/4 bakers make in 1 1/2 hours? Explain your reasoning.
Answer:
27.91 pretzels.
Step-by-step explanation:
Knowing that 1/3 of 33 bakers can make 89 pretzels in 2 1/2 hours, to determine how many pretzels can 5 3/4 bakers make in 1 1/2 hours the following calculation must be performed:
33 x 1/3 = 11
89 / 2.5 / 11 = X
35.6 / 11 = X
3.236 = X
3/4 = 0.75
3.236 x 1.5 x 5.75 = X
4.854 x 5.75 = X
27.91 = X
Therefore, 5 3/4 bakers can make 27.91 pretzels in 1 1/2 hours.

Please this is due at 11/00 pm help me please
Answer and Step-by-step explanation:
The answer is 54.
We see that each time, the number is being multiplied by 1.5.
54 times 1.5 = 81 * 1.5 = 108
54 times 2 = 108
54 is the starting number, because when you multiply 54 by 1, you get 54 for y.
#teamtrees #PAW (Plant And Water)
Answer: y = 54x
The easiest way to do this is by looking at the column where x = 1. In that column, y = 54, so we know that x times 54 would be equal to y.
If you don't have a column where x = 1, you can divide the y value by the x. Here are two examples:
27 ÷ 0.5 = 54
81 ÷ 1.5 = 54
write the point-slope form of the equation of the line described.
1. through: (-2, 5), slope =6
2. passing through the following points:
x y
7 19
8 22
9 25
10 28
Answer:
6x - y + 17=0
Step-by-step explanation:
Given :-
The slope of the line is 6 and it passes through (-2,5) .And we need to find out the equation of the line. Using the point slope form. The point slope form of the line is ,
[tex]:\implies[/tex] m ( x - x1) = ( y - y1)
[tex]:\implies[/tex] 6( x -(-2)) = ( y -5)
[tex]:\implies[/tex] 6( x +2) = y -5
[tex]:\implies[/tex] 6x +12= y -5
[tex]:\implies[/tex] 6x - y +17=0
Hence the equation of the line is 6x - y +17=0-21+2(3-15)-(-3)(+7)+(-3)(-8)
Answer:
[tex] - 21 + 2(3 - 15) - ( - 3)( + 7) + ( - 3)( - 8) \\ = - 21 - 24 + 21 + 24 \\ = 0[/tex]

How would the graph of the function y=|x|-4 be affected if the function were changed to y=|x|-1?
Answer:
[tex]y =|x| - 4[/tex] is translated 3 units up
Step-by-step explanation:
Given
[tex]y =|x| - 4[/tex]
Required
The changes that makes it to: [tex]y =|x| - 1[/tex]
By observation, we can see that [tex]y =|x| - 4[/tex] was translated up to [tex]y =|x| - 1[/tex]
Next, is to calculate the units of translation (c)
Represent the old function as:
[tex]y=\left|x\right|-4 + c[/tex]
Equate y and y
[tex]\left|x\right|-4 + c =\left|x\right|-1[/tex]
Cancel out |x|
[tex]-4 + c=-1[/tex]
Solve for c
[tex]c = 4 - 1[/tex]
[tex]c = 3[/tex]

Answer:
D. x ≈ 2.60
Step-by-step explanation:
After graphing both of these equations separately, we can see that they meet at a point of x = 2.59, therefore the answer to this question would be D. Both values also seem to meet at an x value of -0.548 but it is not an option in this question, probably because the y output value is close not the same for both equations.

What are the end behaviors of f(x) = (1/3)^x – 2 ?
Answer:
[tex]\lim_{x\to -\infty} f(x)=\infty,\\\lim_{x\to \infty} f(x)=2,[/tex]
Step-by-step explanation:
The end behaviors of a function simply denote where the function is headed at x approaches negative and positive infinity. In [tex]f(x)=\left(\frac{1}{3}\right)^x+2[/tex], as [tex]x[/tex] gets approaches [tex]-\infty[/tex], the function will approach [tex]y=\infty[/tex]. As [tex]x[/tex] approaches [tex]\infty[/tex], the function will approach [tex]y=2[/tex].
We can write this in the following format to denote these end behaviors:
[tex]\lim_{x\to -\infty} f(x)=\infty,\\\lim_{x\to \infty} f(x)=2,[/tex]
A hot air balloon holds 1,592 cubic meters of helium. The density of helium is 0.1785 kilograms per cubic
rounded to the nearest tenth of a kilogram?
1202 ka
Answer: 285.2 kg
Step-by-step explanation:
Given
The volume of helium in the balloon is [tex]V=1592\ m^3[/tex]
The density of the helium is [tex]\rho =0.1785\ kg/m^3[/tex]
Mass of the helium gas is given by the product of density and volume
[tex]\Rightarrow M=\rho \cdot V\\\Rightarrow M=0.1785\times 1592\\\Rightarrow M=285.2\ kg[/tex]
Thus, the mass of gas is 285.2 kg
