Alice has 15 times as many crayons as Bryan. Write an equation to find the total number of crayons that Alice has.
Answer:
a = 15b
Step-by-step explanation:
It's given in the question that Alice has 15 times as many crayons as Bryan.
Let the number of crayons with Bryan = b
And the number of crayons with Alice = a
Therefore, equation representing the number of crayons with Alice will be,
a = 15b

13. Every Friday, milkshakes are on sale at The Ice Cream Shoppe with a 15% discount.
13a) The regular price of a milk shake is $4. What is the discount price?
13b) If the regular price of a shake is X dollars, what is the discount price in dollars?
13c) On your birthday, the discount price of an ice cream cake is $22. What is the regular price?
(*I really need help on this T^T*)
Answer:
13a) $3.40
13b) 0.85X
13c) $25.88
Step-by-step explanation:
13a) When there is a 15% discount, we can say that we are only paying 85% of the original price because out of 100%, 15% is taken away. 85% in decimals is 85/100 = 0.85.
$4 x 0.85 is the discounted price, which is $3.40
13b) In 13a, the price was 4. Now, the price is X. Hence we plug in (substitute) X in for 4, giving us X x 0.85, which we can write as 0.85X
13c) 85% of the cake is $22. To find 100% of the price, we can find 1% of the original price and then multiply that by 100, which gives us 100% of the price.
We know 85% of the original price. Therefore, dividng the price by 85 will give us 1% of the price. 1% = $22/85
Finally, to calculate 100%, we multiply by 100.
22/88 x 100 = 440/17 which is 25.882 in decimals, which we round to 2 decimal places (because it is currency) = $25.88

A campus courtyard is in the shape of a rectangle and consists of grass surrounded by a concrete path. The dimensions of the
entire courtyard are 25 ft. by 20 ft. The concrete path is 3 feet wide all the way around. The school decides to replace the
grassy area. A landscaping company charges $.20 per square foot for grass and $.60 per square foot to install it.
Approximately how much would the school save if the math club volunteered to install it instead of having the landscape
company install it?
Answer:
I think they'd be saving approximately $300
Step-by-step explanation:
25 times 20 is 500. 500 times .6 is 300 bucks.

Nieves y Ana juegan tres partidas partidas. Nieves tenía 10 cromos y Ana 80. En la primera partida ganó Nieves y elevó sus cromos al cuadrado, en la segunda perdió el cubo de 3, y en la tercera perdió el cuadrado de 4. ¿Cuántos cromos les quedan a Ana y a Nieves?¿Quién ha ganado?
Answer:
A Nieves le quedan 57 cromos y a Ana 33.
Nieves ha ganado 47 cromos
Step-by-step explanation:
Para la primera partida, el cuadrado de los cromos de Nieves es de 100.
El cubo de 3 es 27. Nieves queda con 100-27 = 73 cromos
El cuadrado de 4 es 16. Nieves queda con 73-16 = 57 cromos
A Nieves le quedan 57 cromos
A Ana 90-57 = 33 cromos
Así, Nieves ha ganado 57-10 = 47 cromos

a new computer costs 950$ but it depreciates in value by about 14% each year.At this rate,how much will it be worth in 6 years?
Step-by-step explanation:
950x14= 13 300
13300/100
133$ per year
133x6years= 798$
so 950-798= 152
152$ will be the price of the pc at this rate you said
The graph of quadratic function f(x) has a minimum at (-2,- 3 and passes through the point (2, 13). The functio
g(x) is represented by the equation g(x)= -(x+2)(x-3)
How much greater is the y-intercept of g(x) than f(x)?
Answer:
Step-by-step explanation:
hello :
the vertex -form of quadratic function f(x) is : f(x) = a(x+b)²+c
the vertex : (- b , c )
means : (-2,-3) so : -b = -2 and c = - 3 so : b =2 and c = -3
f(x) = a(x+2)²-3
calculate : a
the graph passes through the point (2, 13) : f(2)=13
means : a(2+2)²-3 = 13
16a - = 13
16a = 16 so : a = 1
f(x) is represented by the equation f(x) = (x+2)²-3
The graph of f(x) color red and g(x) blue
is the y-intercept when g(x) greater g(x) than f(x) is when x=0 so : y = 6
which is not equivalent to 24y-12
Answer:
what are the answer choices
Step-by-step explanation:
The linear expression 24y - 12 is not equivalent to the expression 2(12y - 12) option (A) 2(12y - 12) is correct.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
We have a linear expression:
= 24y - 12
From the above linear expression take 2 as a common factor:
= 2(12y - 6)
Take 2 as common factor again:
= 2(2)(6y - 3)
= 4(6y - 3)
Now, take 3 as a common factors:
= 12(2y - 1)
The expression 24y - 12 is equivalent to the expressions 2(12y - 6), 4(6y - 3), and 12(2y - 1).
Thus, the linear expression 24y - 12 is not equivalent to the expression 2(12y - 12) option (A) 2(12y - 12) is correct.

Answer:
JL = 38
Step-by-step explanation:
Since JK ≅ KL , then Δ JKL is isosceles and KM is a perpendicular bisector, so
JM = ML , that is
14x - 9 = 8x + 3 ( subtract 8x from both sides )
6x - 9 = 3 ( add 9 to both sides )
6x = 12 ( divide both sides by 6 )
x = 2
Then
JL = 14x - 9 + 8x + 3 = 22x - 6 = 22(2) - 6 = 44 - 6 = 38
Stacy made 3 of her car payments late and was fined 3 late fees. The total change to her savings from late fees was - $24. How much was each late fee?
Answer:
$8
Step-by-step explanation:
I got my answer of $8 because I knew that the total amount of money she was charged for late fees was $24, and she was charged for 3 late fees. Then, I did $24 divided by 3 late fees and got $8 per late fee as my answer.
24 divided by 3 equals 8.
The Statue of Liberty is about 300 feet tall and about 30 feet wide. The town of Unionville is building a smaller model for their Fourth of July celebration. Unionville's statue will be 3 feet wide.
Answer:
Step-by-step explanation:
The width of the actual statue is 30 feet and that of the model is 3 ft. What is the scale? 3 ft divided by 30 ft is 1/10.
The smaller model will be 1/10 the size of the actual Statue of Liberty.
Answer:
Solution :-Tall : Width
300 : 30
x : 3
By cross multiplication
3(300) = 30(x)
900 = 30x
900/30 = x
30 = x

Let f (x) = -1/2(x + 2)+ 5
-3 to x=1?
What is the average rate of change for the quadratic function from x=-3 to x=1
Answer:
Rate of change = -1
Step-by-step explanation:
Given:
f(x) = -½(x + 2)² + 5
Required:
Average rate of change from x = -3 to x = 1
Solution:
Rate of change = [tex] \frac{f(b) - f(a)}{b - a} [/tex]
Where,
a = -3,
f(a) = f(-3) = -½(-3 + 2)² + 5 = -½(-1)² + 5 = 4.5
b = 1,
f(b) = f(1) = -½(1 + 2)² + 5 = -½(9) + 5 = 0.5
Plug in the values into the formula:
Rate of change = [tex] \frac{0.5 - 4.5}{1 - (-3)} [/tex]
Rate of change = [tex] \frac{-4}{4} [/tex]
Rate of change = -1
what are all possible values for x in the equation x^3=375?
can you please solve this step by step?

Answer:
[tex]x=5\sqrt[3]{3}[/tex] or 7.21
Step-by-step explanation:
x³ = 375
You have to take the square root and have the index 3:
You have to have the index 3 because x is cubed and you have to get rid of the cubed sign since a normal square root is for when the exponent is 2:
[tex]\sqrt[3]{x^3} =\sqrt[3]{375} \\x=5\sqrt[3]{3}[/tex]
In decimal form (rounded to hundredths):

hasil dari 64^5/6 + 27^2/3 - 81^3/4 adalah
tolong bantuannya kakak kakak
Answer:
14
Step-by-step explanation:
Given the indicinal expression 64^5/6 + 27^2/3 - 81^3/4
According to indices;
[tex]a^{m/n} = (\sqrt[n]{a}) ^m[/tex]
Applying this to the question
[tex]64^{5/6} \\= (\sqrt[6]{64}) ^5\\= 2^5= 32[/tex]
Similarly
[tex]27^{2/3}\\= (\sqrt[3]{27}) ^2\\= 3^2\\= 9\\[/tex]
Also;
[tex]81^{3/4}\\= (\sqrt[4]{81}) ^3\\= 3^3\\= 27[/tex]
Substitute inti the original equation
64^5/6 + 27^2/3 - 81^3/4
= 32 + 9- 27
= 41 - 27
= 14
Hence the required answer is 14
