Answer:
$112.80
Step-by-step explanation:
If he earns $0.235 per pack, and there are 480 packs, then our equation is:
0.235 x 480 = $112.80
The amount of money earned by Eddie for packing and sealing packs of 480 pens is $112.8
What is unitary method?
The method in which first we find the value of one unit and then the value of the required number of units is known as the Unitary Method.
According to the given question.
Amount of money charged by Eddie for packing and sealing a pack of pens = $0.235
Therefore,
The amount of money charged by Eddie for packing and sealing packs of 480 pens
= 480 × $0.235
= $112.8
Hence, the amount of money earned by Eddie for packing and sealing packs of 480 pens is $112.8

Use inverse operations to find the inverse of y = 27x?
The inverse of y = 27x3 is y =
Answer:
y = (∛x)/3
Step-by-step explanation:
To undo the multiplication by 27, you multiply by its inverse:
(1/27)y = (1/27)(27x^3)
y/27 = x^3 . . . . . . . . . . . simplify
To undo the cube, you take the cube root:
(∛y)/(∛27) = ∛(x^3)
(∛y)/3 = x
Apparently, you want the inverse function, so you swap the variables:
y = (∛x)/3
_____
You can swap the variables at the beginning or end. It doesn't matter. If you do it at the beginning, you have ...
x = 27y^3
and you're solving for y. You use the same inverse operations that we used above.
6x + 2y = 18 -4x - 2y = -6
Answer:
x=6, y = -9
Step-by-step explanation:
6x + 2y = 18
-4x - 2y = -6
Add the two equations together to eliminate y
6x + 2y = 18
-4x - 2y = -6
------------------------
2x +0y = 12
Divide by 2
2x/2 = 12/2
x = 6
Then find y
6x+2y = 18
6*6 +2y = 18
36+2y = 18
Subtract 36 from each side
36+2y-36 = 18-6
2y = -18
Divide by 2
2y/2 = -18/2
y = -9

The graph shows a relationship between the number of cupcakes purchased, n, and the total cost of the order, t. The Soaring Cupcake charges a $15 initial fee and then $3.00 for every cupcake purchased. What is the total cost for 15 cupcakes? What is the total cost for 10 cupcakes? How many cupcakes can you order for $30? Write a function rule in function notation for the situation using the variables t and n: A.) Does an input value of 4 make sense for this situation, why? B.) Does an input value of 5.2 make sense for this situation, why?
Answer:
1) $60
2) $45
3) 5 cupcakes ;; function for situation is 30(n)=3n+15
3A) No
3B) No
Step-by-step explanation:
the function is f(x)=3x+15 where x= cupcakes
To find total cost for 15 cupcakes, simply look at the graph or if you don't trust your eyeballing skills, you would calculate it by:
f(15)=3x+15 meaning plug 15 into the equation which equal $60
same for 10 cupcakes
f(10)=3(x)+15 equals $45
# of cupcake order for $30
using the graph we can see that for $30 we can purchase 5 cupcakes
the function for the situation is 30(n)=3n+15
A) No it would not make sense because after substituting 4 for the n, it does not equal to 30
B) Yes it would make sense because substituting 5.2 for n, it equal to $30.6 or $30

Tickets to the movies are $7 for adults and $4 for children. If 272 tickets
sold $1694, then how many of each type were sold?
Answer:
202 tickets for adults were sold and 70 tickets for children are sold.
Step-by-step explanation:
Solve this question using simultaneous linear equation.
•Let the number of tickets sold for adults be a
•Let the number of tickets sold for children be b
The question stated that 272 tickets were sold altogether. So:
[tex]a + b = 272[/tex]
Now, make sure that only one of the unknown values remain on the left hand side. For example:
[tex]a = 272 - b[/tex]
I will refer to the above equation as equation 1.
Now, the question also stated that the tickets sold $1694. This means that:
[tex]7a + 4b = 1694[/tex]
I will refer to this equation as equation 2.
Now, substitute equation 1 into equation 2 by replacing the a in equation 2 with the values on the right hand side in equation 1. For example:
[tex]7(272 - b) + 4b = 1694[/tex]
Then just solve the equation by finding the value of b.
[tex]7(272 - b) + 4b = 1694 \\ 1904 - 7b + 4b = 1694 \\ 1904 - 3b = 1694 \\ 1904 - 1694 = 3b \\ 210 = 3b \\ b = 210 \div 3 \\ = 70[/tex]
Lastly, find the value of a. Just take the value of b and then substitute into equation 1.
[tex]a = 272 - b \\ = 272 - 70 \\ a = 202[/tex]

In a family of 4 children under 10 years old, the sum of the square of the ages of the 3 youngest is equal to the square of the age of the oldest. How old are these children
Answer: 2, 3, 6 and 7.
Step-by-step explanation:
We have four natural numbers A, B, C and D.
such that all of these numbers are smaller than 10, and:
A < B < C < D.
A, B and C are the ages of the smaller ones, and D is the age of the larger kid.
Now we have the relation
A^2 + B^2 + C^2 = D^2
We can write this as:
D = √(A^2 + B^2 + C^2)
And remember that D must be smaller than 10, then now we can play with the numbers A, B and C in order to find D.
Suppose for example:
A = 1, B = 2, C = 3
D = √( 1^2 + 2^2 + 3^2) = √(1 + 4 + 9) = √14
This is not a whole number.
Then we have that A^2 + B^2 + C^2 must be a perfect square.
The perfect squares we can aim for are:
4*4 = 16
5*5 = 25
6*6 = 36
7*7 = 49
8*8 = 64
9*9 = 81
now, looking at that comes to my mind to try to reach the 49.
because we can take the 36, add 4 to that (4 = 2*2) and then add 9 (9 = 3*3)
A^2 + B^2 + C^2 = 49
where we can use:
A = 2. B = 3 and C = 6
2^2 + 3^2 + 6^2 = 4 + 9 + 36 = 49
Then we have:
D = √(2^2 + 3^2 + 6^2 ) = √49 = 7
Then the ages of the children (for smallest to largest) are:
2, 3, 6 and 7.
what is the additive of p when p = -19.57
The additive inverse of a number is just the opposite of the given number. For example; 2 and the additive inverse is -2.
If we apply this to the number we are given, we get 19.57

Tai’s baby brother weighs 3,745 grams. What is his weight in kilograms? A. 0.3745 kg B. 3.745 kg C. 37.45 kg D. 374.5 kg
Answer:
My answer to the question is 3.745kg.
Option B
The required weight of Tai's baby brother weighs 3,745 grams in kilograms is 3.745 kg. Option B is correct.
Given that,
Tai’s baby brother weighs 3,745 grams. What is his weight in kilograms is to be determined.
A kilogram is the standard unit of measurement of weight.
What is arithmetic?In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
Here,
1 kilogram = 1000 gram
1 gram = 1 / 1000 kilogram
Multiply both side by 3,745
3,745 gram = 3,745 / 1000 kilogram
3,745 gram = 3.745 kilogram
Thus, the required weight of Tai's baby brother weighs 3,745 grams in kilograms is 3.745 kg. Option B is correct.

and remain within his budget?
Help please

Step-by-step explanation:
3x - y = 74
4y = x
Replace x in the first expression by 4y
3x - y = 74 ➡ 3(4y) - y = 74
12y - y = 74
11y = 74
y = 74/11 we can use this to find x
4y = x
4 × 74/11 = x
296/11 = x
