Chicos estoy en un aprieto ayudarme pls Sabiendo que una falda es 5 € más cara que una blusa y que si compro 6 faldas y 4 blusas pago 480 €, ¿cuánto vale la falda?
Answer:
El precio de la falda es 50 €.
Step-by-step explanation:
Lo que sabemos:
[tex] F = 5 + B [/tex] (1)
En donde F es por falda y B por blusa.
Si compras 6 faldas y 4 blusas y pagas 480 €:
[tex] 6F + 4B = 480 [/tex] (2)
Entonces, al introducir la ecuación (1) en (2) podemos hallar el precio de cada falda.
[tex] 6F + 4B = 480 [/tex]
[tex]6(5 + B) + 4B = 480[/tex]
[tex] 10B = 480 - 30 [/tex]
[tex]B = \frac{450}{10} = 45[/tex]
Finalmente, el precio de la falda se puede encontar con la ecuación (1):
[tex]F = 5 + 45 = 50[/tex]
Por lo tanto, el precio de la falda es 50 €.

Wally blew 1/4 of his income last week on video
games and 1/8 on fast food. If Wally spent a
combined $84 on these two things, what was his
income last week?
games and
Answer:
(hope this is right)
$224
Step-by-step explanation:
If he spent 1/4 on video games and 1/8 on food then Wally spent 3/8 of his income.
84 divided by 3 is 28
28 times 8 would be 224 dollars total of his income.

Answer:
The answer is D
Step-by-step explanation:
Because both when we multiply we will get the same answer
Answer:
It would be B. 8x3/5
Step-by-step explanation:
So when multiplying fractions, you multiply the denominator of one fraction by the denominator of the other. You then multiply the numerator of one fraction by the numerator of the other.
The 8, can be turned into fraction form by thinking of it as 8/1 x 3/5.
And thinking about how we do denominator x denominator, numerator x numerator, it will look like:
[tex]\frac{8*3}{1*5}[/tex]
There is one more thing we need to simplfy before we will get our answer.
When you multiply a number by 1, what do you get? The same exact number as before.
Sp tecnically, 1*5 would just be 5:
[tex]\frac{8*3}{5}[/tex]
This looks like answer b!
Hope this helps!

Answer:
.62
Step-by-step explanation:
first move the decimal 3 places to make it a whole number and now we have 4960, now we divide 4960 by 8 giving us 620, now we move the decimal 3 places back and it gives us the decimal .62.
The movement of moving particles is described in the equation r=ht22 −2vt−2c. Solve the equation for v.
Pls help
Answer:
[tex]v=\dfrac{r-ht^2+2c}{-2t}[/tex]
Step-by-step explanation:
The given equation is :
[tex]r=ht^2 -2vt-2c[/tex]
We need to solve the above equation for v.
Subtract ht² from both sides.
r-ht²= ht²-2vt-2c-ht²
r-ht² = -2vt-2c
Adding 2c both sides,
r-ht² +2c= -2vt-2c+2c
r-ht² +2c = -2vt
Dividing both sides by (-2t)
[tex]v=\dfrac{r-ht^2+2c}{-2t}[/tex]
So, the value of v is equal to [tex]\dfrac{r-ht^2+2c}{-2t}[/tex].
Which arithmetic sequence has a first term equal to 47 and a common difference of -18?
a.{-18, -65, -112, -159, …}
b.{47, 29, 11, -7, …}
c.{-18, 29, 76, 123, …}
d.{47, 65, 83, 101, …}
Answer:
b
Step-by-step explanation:
There are 2 sequences with a₁ = 47, b and d
The common difference of both is
(b)
d = a₂ - a1 = 29 - 47 = - 18
(d)
d = a₂ - a₁ = 65 - 47 = 18
The the sequence with first term 45 and common difference - 18 is b
The required sequence which has a first term equal to 47 and a common difference of -18 is {47, 29, 11, -7, …}. Option B is correct.
What is arithmetic progression?Arithmetic progression is the series of numbers that have common differences between adjacent values
What is geometric progression?Geometric progression is a sequence of series whose ratio with adjacent values remains the same.
Here,
An arithmetic sequence has a first term equal to 47 and a common difference of -18,
a = 47
d = -18
The sequence formed given as,
⇒ a, a + d, a + 2d, a + 3d
⇒ 47, 47 - 18, 47 + 2(-18), 47 + 3(-18)
⇒ 47 , 29, 11, -7 . . . . .
Thus, the above sequence matches the sequence given in option b.

Step-by-step explanation:
A bookstore costs $75 a day to keep open, and spends $10 for each book it
sells. The store charges $15 for each book it sells. If n represents the number
of books sold, which equation represents the revenue function for this
bookstore?
A. r= 15n
B. r= 25n
C. r= 10n
D. r= 75n
Answer: A. r= 15n
Step-by-step explanation: took the quiz.
The solution is, The cost function of this bookstore is 10n + 75.
What is cost function?A cost function is a formula used to predict the cost that will be experienced at a certain activity level.
here, we have,
According to the given problem,
Cost to open bookstore for a day - $75
Price for selling each book = 10
Considering number of books to be n,
Total cost for selling each book = $(10×n)
Therefore total cost price = $( 10n + 75)
Hence, we can conclude that the total cost function of this bookstore is represented by equation 10n + 75

At a store, 7 out of the first 10 people who entered were
carrying a purse. Based on this information, if 250
people enter that store in one day, how many people
could be expected to be carrying a purse?
175/250 or %70
Hope this answers your question!
Answer:
175 people would be expected to be carrying a purse.
Step-by-step explanation:
7/10 people who entered were carrying a purse and if you say 250 people entered the store in one day the number of people would now be 250 instead of 10.
Since I made it into a fraction form you would need to find a numerator that would make the ratio equal. 7/10 = ?/250 Since 10 is a factor of 250 you would divide 250 by 10 and you would get 25. Since 10 * 25 is 250 you would also multiply the numerator, which is 7, by 25. 7 * 25 is 175. The ratio 7/10 = 175/250 is now equal.
The answer would be 175 would be expected to be carrying a purse since I had made the numerator of the fraction the number of people who were expected to bring a purse and the denominator the number of people entering the store.

Answer:
2*(3*4) = 41/16
Step-by-step explanation:
Your function is not carefully defined.* We assume you intend ...
f(a, b) = (2a +3b)/(a +b)
and you want to find ...
f(2, f(3, 4))

Filling in the values and doing the arithmetic, we have ...
[tex]2*(3*4)=\dfrac{2\cdot2+3\cdot\dfrac{2\cdot3+3\cdot4}{3+4}}{2+\dfrac{2\cdot3+3\cdot4}{3+4}}=\dfrac{4+3\cdot\dfrac{18}{7}}{2+\dfrac{18}{7}}\\\\=\dfrac{4\cdot7+3\cdot18}{2\cdot7+18}=\dfrac{82}{32}=\boxed{\dfrac{41}{16}}[/tex]

Answer:
B
Step-by-step explanation:
√16/25 = 4/5 = 0.8-> (4/5 x 4/5 = 16/25)
(2/5)^3 = 8/125 = 0.064
-(-0.3)^3 = 0.027 (an odd exponent mantains the same sign of the number and minus x minus = +)
-√169 = -13
-13 is a negative number so it is surely the smallest
2 is minor than 6 so we have that 0.027 is minor than 0.064
8 is major than 0, so 0.8 is the greatest number
we have
-√169 ; -(-0.3)^3 ; (2/5)^3 ; √16/25
