b) 27 unidades cuadradas
c) 721
Step-by-step explanation:
a) ¿Cuál es el valor de un bolígrafo cuando la docena se compra por $ 7848?
Una docena = 12
Por eso:
12 bolígrafos = $ 7848
1 bolígrafo = $ x
Cruz multiplicar
12 bolígrafos × $ x = 1 bolígrafo × $ 7848
$ x = 1 bolígrafo × $ 7848/12
$ x = $654

Amaya went to the pet store. She bought x fish for $3.50 each. She bought fish food for $7.00, and a fish bowl for $12.75. Determine how much Amaya spent at the pet store if she bought 4 fish.
Answers
Answer:
$93
Step-by-step explanation:
Amaya went to the pet store. She bought x fish for $3.50 each. She bought fish food for $7.00, and a fish bowl for $12.75. Determine how much Amaya spent at the pet store if she bought 4 fish.
Step 1
We calculate the total amount spent on 1 fish
= Cost of fish + Cost of food + Cost if bowl
= $3.50 + $7.00 + $12.75
= $23.25
Step 2
The total amount spent on 4 fishes is calculated as
= $23.25 × 4 fishes
= $93

Which pair of functions are inverses of eachother?
Answers
Answer:
D
Step-by-step explanation:
A.
y= 6x³
to find the inverse substitute x for y and y for x and solve for y
x= 6y³ ; divide both sides by 6
x/6 =y³ ; cube root both sides
(∛x)/ ∛6 = y
so (∛x)/6 and 6x³ are NOT inverse of each other
B
y= (x+2)/5
x= (y+2)/5; multiply by 5
5x = y+2; subtract 2
y= 5x-2 NOT corect
C
y = 5x-6
x= 5y-6; add 6 to both sides
x+6 = 5y ; divided by 5 both sides
y = (x+6)/5 is NOT correct
D
y=7x -2
x= 7y-2
x+2 = 7y , (x+2) /7 = y so IS correct

S. At Food Lion, 28 of every 35 jars of peanut butter on the shelves are creamy peanut butter. What percent of the jars of peanut butter are not creamy?
Answers
Answer:
7/35 or 20% of the jars are not creamy
Answer:
20%
Step-by-step explanation:
To find the percent of NOT creamy:
35(total peanut butter) - 28(creamy) = 7
Question now is: 7 is what % of 35?
Formula = a(part) = p(percent)*w(whole)
p = a/w
7/35 = 0.2
0.2 is a decimal so multiply by 100 to get 20%
The answer should be 20% so I hope this helps!

At a store, apples cost each and oranges cost each. Harry buys some apples and oranges and spends . He buys a total of pieces of fruit.
Answers
Answer:
Number of apples = 6
Number of oranges = 5
Step-by-step explanation:
At a store, apples cost $0.80 each and oranges cost $0.95 each. Harry buys some apples and oranges and spends $9.55. He buys a total of 11 pieces of fruit.
Let
Number of apples = x
Number of oranges = y
x + y = 11 (1)
0.80x + 0.95y = 9.55 (2)
From (1)
x = 11 - y
Substitute into (2)
0.80x + 0.95y = 9.55 (2)
0.80(11 - y) + 0.95y = 9.55
8.8 - 0.80y + 0.95y = 9.55
- 0.80y + 0.95y = 9.55 - 8.8
0.15y = 0.75
y = 0.75/0.15
y = 5
Substitute y = 5 into (1)
x + y = 11 (1)
x + 5 = 11
x = 11 - 5
x = 6
Number of apples = 6
Number of oranges = 5
