"Shaquille, Lyle, and Amanda collect stamps. Shaquille has one-half the number of stamps that Lyle has. Amanda has two-thirds as many stamps as Lyle. Together they have 364 stamps. How many stamps does Amanda own?" Please help me :c
Answer:
112 stamps
Step-by-step explanation:
Shaquille and Amanda's stamps are described in terms of Lyle's, so:
Lyle's = 6x 6x+3x+2x=364
Shaquille's = 3x 13x=364
Amanda's = 4x x=28
Lyle has 168 stamps, Shaquille has 84, and Amanda has 112. 168+84+112=364

Betty bought 3 packages of chocolate cupcakes and 7 packages of vanilla cupcakes. Each package contains 24 cupcakes. Which equation is NOT a way to find c, the number of cupcakes Betty bought in all?
Answer:
The equation to find the number did cupcakes bought in all =
= 3c + 7c
= c(3 + 7)
The total number Betty bought in all = 240 cupcakes.
Step-by-step explanation:
Let the amount of cupcakes in a package be represented by c
Betty bought 3 packages of chocolate cupcakes and 7 packages of vanilla cupcakes.
The equation to find the number did cupcakes bought in all =
3 × c + 7 × c
= 3c + 7c
= c(3 + 7)
Each package contains 24 cupcakes
The total number = 3(24) + 7(24)
= 240 cupcakes.

Which best represents 3=x/6 -2
Answer:
30
Step-by-step explanation:
Answer: x = 30
Step-by-step explanation: To solve for x, first you’ll have to make sure that your result will equal to 3. ( x/6 -2). Next, look for a numerator that can make a fraction that equals to 5. Then, you would have to multiply 6 x 5, which equals to 30, so 30 will be x. 3 = (30/6 - 2) 3 = 5-2.
Question
Help me -.8+ 2X = .3 - x
Step-by-step explanation:
2x+x=.3+.8
3x= 1.1/:3
x=0.366
Answer:
x = -2.566667
Step-by-step explanation:
simplify both sides
8 + 2x = 0.3 - x
8 + 2x = 0.3 + - x
2x + 8 = - x + 0.3
add x to both sides
2x + 8 + x = - x + 0.3 + x
3x + 8 = 0.3
subtract 8 from both sides
3x + 8 - 8 = 0.3 - 8
3x = -7.7
divie both sides by 3
3x/3 = -7.7/3
x = -2.566667

Whitney has £265 Nancy has £180 They each spend the same amount of money. Whitney has twice as much money as Nancy left now. How much money did they each spend?
Answer:
£95
Step-by-step explanation:
Given that:
Whitney's initial amount = £265
Nancy's initial amount = £180
Let amount each spent = x (amount is the same)
After spending Whitney has twice as much money as Nancy.
Amount spent by each?
(Whitney's initial amount - x) = 2(Nancy's initial amount - x)
265 - x = 2(180 - x)
265 - x = 360 - 2x
-x + 2x = 360 - 265
x = £95
Hence, they both spent £95

If you want to buy an item in a store that costs $32.50 and is on sale for 30% off, then how much would the item actually cost you after the discount? Round to the nearest cent.
Answer:
22.80
Step-by-step explanation:
100% - 30% = 70% that you'll be paying
70% = [tex]\frac{70}{100}[/tex] = 0.7
0.7 * 32.50 = 22.75
Round to nearest cent: 22.8
Which of these statements best describes the relation shown in Item 1?
A- A function that is one-to-one
B-A function that is many-to-one
C-A function that is one-to-many
D-A relation that is not a function
Answer:
The relation is 'a function that is one-to-many'.
Step-by-step explanation:
From the table, we can see that element 10 i.e. y=10 in the range, corresponds to two elements i.e. x=-5, and x=5 in the domain.
In other words, the given table represents the many-to-one function as an element of the range y = 10 corresponds to more than one element in the domain.
Therefore, the relation is 'a function that is one-to-many'.
The statements that best describe the relation shown in Item 1 is one to many. Option C is correct
Functions are represented as mappings to relate the domain of the given function with the co-domain.
For instance, the function y= x + b has a domain of x and the codomain of "y"
Mappings can be one to one, where each value of the domain is a unique value in the co-domain
Many to one where one element in the domain have more than one element in the codomain
From the given table, we can see that when y = 10, the corresponding x values are 5 and -5. his shows that the codomain value (10) has more than one unique value in the domain.
Hence the statements that best describe the relation shown in Item 1 is a one to many
