If x+2y=12 and x-y=3 find the value of x+y

Answers

Answer 1
The answer would be 9

x-y=3
x=3+y

X+2y=12
(3+y) + 2y=12
3y+3=12
3y=9
Y=3

X-(3)=3
X=6

X+y
6+3=9

Trevon and Ashley are selling cookie dough for a school fundraiser. Customers can buy packages of chocolate chip cookie dough and packages of gingerbread cookie dough. Trevon sold 6 packages of chocolate chip cookie dough and 2 packages of gingerbread cookie dough for a total of $72. Ashley sold 6 packages of chocolate chip cookie and 10 packages or gingerbread cookie dough for a total of $216. What is the cost if each of one package of chocolate chip cookie dough and one package of gingerbread cookie dough

Answers

Answer:

the cost of one package of chocolate chip cookie and one package of ginger bread is $6 and $18 respectively

Step-by-step explanation:

The computation of the cost of one package of chocolate chip cookie and one package of ginger bread is shown below:

Let us assume the package of chocolate chip cookie be x

And, the package of ginger bread is y

So,

According to the question

6x + 2y = $72

6x + 10y = $216

Now subtract equation 1 from equation 2

-8y = -144

y = $18

And, for x it would be

6x + $36 = $72

x = $6

Hence, the cost of one package of chocolate chip cookie and one package of ginger bread is $6 and $18 respectively

Jailyn has ½ of a pizza left over. She wants to share the pizza with 3 of her friends. What fraction of the original pizza will Jailyn and her 3 friends each receive?

Answers

Answer:

Jailyn and her 3 friends will each receive 1/8 of the original pizza.

Step-by-step explanation:

Given that Jailyn has ½ of a pizza left over and she is sharing that with 3 friends, it means that the left over will be divided in 4 pieces and you have to divide 1/2 by 4 to find the fraction of the original pizza that Jailyn and her 3 friends will each receive:

[tex]\frac{1}{2}[/tex]÷4= [tex]\frac{1}{2}[/tex]÷[tex]\frac{4}{1}[/tex] = [tex]\frac{1*1}{2*4}[/tex] = [tex]\frac{1}{8}[/tex]

According to this, the answer is that Jailyn and her 3 friends will each receive 1/8 of the original pizza.

Answer:

D. The probability of selecting an orange is ³/₅.

Step-by-step explanation:

A is incorrect because there would be 4 apples combined (3 from bag one, 1 from bag two). That makes the chance of selecting an apple 2/5 (40%), not 3/10 (30%).

B & C are incorrect because 4/10 (40%) is less than 6/10 (60%)

That leaves D, which state that you have a 60% (3/5) chance selecting an orange, as our answer. That is correct as 3/5 = 6/10 = 60%.

Con las cuatro cartas que se muestran en la figura se pueden formar diferentes números. Por ejemplo: 8232 o 3822. ¿Cuántos números pares de cuatro dígitos y diferentes puedes formar con estas cuatro cartas? ayuda es para un examen TT

Answers

Answer:

Se pueden formar 9 números pares.

Step-by-step explanation:

Dado que con cuatro cartas se pueden formar diferentes números, como por ejemplo 8232 o 3822, para determinar cuántos números pares de cuatro dígitos y diferentes puedes formar con estas cuatro cartas se debe realizar la siguiente tabla:

8232 - 8322 - 8223 = 2 pares 1 impar

2832 - 2823 - 2382 - 2328 - 2283 - 2238 = 4 pares 2 impares

3822 - 3282 - 3228 = 3 pares

Por lo tanto, se pueden formar 9 números pares.

Jessica is buying several bunches of bananas to make desserts for a fundraiser. She can buy 10 pounds of bananas for $14.90 or 8 pounds of bananas for $12.08.

Part A
How much does each pound of bananas cost in each case?
Drag the tile with the cost of each pound to the correct box.
Each tile may be used once or not at all. And part b plz help

Answers

Each pound of bananas costs $1.49 when buying 10 pounds, and $1.51 when buying 8 pounds.

What is Pound?

The standard unit of money in the United Kingdom, equivalent to 16 ounces (or 0.454 kilograms), is used in most English-speaking countries. For more information, see measure. also known as the pound sterling.

According to question:

Let the cost per pound of bananas be represented by x. Then we can set up the following system of equations:

[tex]10x &= 14.90 \\8x &= 12.08[/tex]

Solving for $x$ in each equation, we get:

x = 14.9/10 =  1.49

x = 12.08/8 = 1.51

Therefore, each pound of bananas costs $1.49 when buying 10 pounds, and $1.51 when buying 8 pounds.

£490 is divided between Richard, Stephen & Bridget so that Richard gets twice as much as Stephen, and Stephen gets three times as much as Bridget. How much does Stephen get?

Answers

Answer:

Stephen gets £147

Step-by-step explanation:

Given

Let

[tex]S = Stephen; B = Bridget; R = Richard[/tex]

So:

[tex]S + B + R = 490[/tex]

[tex]R = 2S[/tex]

[tex]S = 3B[/tex]

Required

Find S

Make B the subject in [tex]S = 3B[/tex]

[tex]B = \frac{S}{3}[/tex]

Substitute: [tex]R = 2S[/tex] and [tex]B = \frac{S}{3}[/tex] in [tex]S + B + R = 490[/tex]

[tex]S + \frac{S}{3} + 2S = 490[/tex]

Take LCM

[tex]\frac{3S + S + 6S}{3}= 490[/tex]

[tex]\frac{10S}{3}= 490[/tex]

Solve for S

[tex]S = \frac{490 * 3}{10}[/tex]

[tex]S = 49 * 3[/tex]

[tex]S = 147[/tex]

Stephen gets £147

The base of an isosceles triangle is 16 cm long. The equal sides are each 22 cm long. Find the height of the triangle.

Answers

Given:

The base of an isosceles triangle is 16 cm long.

The equal sides are each 22 cm long.

To find:

The height of the triangle.

Solution:

We know that the altitude of an isosceles triangle divides the base into two equal parts as shown in the below figure.

According to the Pythagoras theorem:

[tex]Hypotenuse^2=Perpendicular^2+Base^2[/tex]

Using Pythagoras theorem, we get

[tex]22^2=h^2+8^2[/tex]

[tex]484=h^2+64[/tex]

[tex]484-64=h^2[/tex]

[tex]420=h^2[/tex]

Taking square root on both sides, we get

[tex]\sqrt{420}=h[/tex]                  (Because side cannot be negative)

[tex]2\sqrt{105}=h[/tex]

Therefore, the height of the isosceles triangle is [tex]2\sqrt{105}[/tex] cm. Approximate height is 20.49 cm.

Find the limit of the function algebraically.

Answers

Given:

The given limit problem is:

[tex]\lim_{x\to 0}\dfrac{x^2+3}{x^4}[/tex]

To find:

The value of the given limit problem.

Solution:

We have,

[tex]\lim_{x\to 0}\dfrac{x^2+3}{x^4}[/tex]

In can be written as:

[tex]\lim_{x\to 0}\dfrac{x^2+3}{x^4}=\lim_{x\to 0}\dfrac{x^2}{x^4}+\dfrac{3}{x^4}[/tex]

[tex]\lim_{x\to 0}\dfrac{x^2+3}{x^4}=\lim_{x\to 0}\dfrac{1}{x^2}+\dfrac{3}{x^4}[/tex]

After applying limits, we get

[tex]\lim_{x\to 0}\dfrac{x^2+3}{x^4}=\dfrac{1}{0^2}+\dfrac{3}{0^4}[/tex]

[tex]\lim_{x\to 0}\dfrac{x^2+3}{x^4}=\infty+\infty[/tex]

[tex]\lim_{x\to 0}\dfrac{x^2+3}{x^4}=\infty[/tex]

Therefore, the value of the given limit problem is [tex]\infty[/tex].
