Answer:

no solutions

Step-by-step explanation:

−2(x−7)+3(x+5)=x+9

Distribute

-2x +14 +3x +15 = x+9

Combine like terms

x + 29 = x+9

Subtract x from each side

x+29 -x = x+9-x

29 = 9

This is never true so there are no solutions

Answer:

It is wrong Problem

Step-by-step explanation:

-2x+14+3x+15=x+9

Answer:

1/2 litros es igual a la capacidad que le pidió su mamá.

Step-by-step explanation:

Para encontrar la respuesta debes escribir 0.5 como fracción. Para hacerlo, el numerador es el número original sin el punto decimal y para definir el denominador debes determinar cuántos digitos decimales tienes. En este caso, el número tiene un dígito decimal, por lo cual el denominador es 10. De acuerdo a esto:

0.5 se escribiría como [tex]\frac{5}{10}[/tex] y esta fracción se puede simplificar porque los dos números son divisibles entre 5:

5/5= 1

10/5= 2

Por esto, 0.5= [tex]\frac{1}{2}[/tex]

Esto significa que 1/2 litros es igual a la capacidad que le pidió su mama.

Answer:64

Step-by-step explanation: because 2 multiplied by 2 is 4 four multiplied by 2 is eight as the pattern continues 32 multiplied by 2 is 64.

Answer:

2+2=4

4+4=8

8+8=16

16+16=32

32+32=64

Step-by-step explanation:

There are 4 * 4 = 16 outcomes from spinning these spinners. You get an odd number by multiplying an odd number by an odd number. Since there are 2 odd numbers on both spinners the successful outcomes are 2 * 2 = 4 so probability is 4 / 16 = 1 / 4.

Answer:

a. 2.5  

b. 2.333

c. 2.85

Step-by-step explanation:

A) 1. subtract -x on both sides              2. to get 3x-1/2=7  

3. Add 1/2 on both sides                    4. to get 3x=7.5    

5. divide 3 on both sides                   6. To get... x=2.5

B)1. Same process.                               2. x+2=13/3        

3. x=13/3-2                                         4. x= 2.33(repeating)

C) 1. same process.                           2. 2x-x/3=3+7/4

3. 2x-x/3=4.75                                  4. Isolate -x/3  

5.-x/3=4.75-2x                                    6. multiply both sides by 3          

7. -x=14.25-6x                                      8. 5x=14.25

9. x= 2.85

Answer:

56.52 units² or 18π units²

Step-by-step explanation:

The formula for the area of a sector is:

A = πr²(x/360°)

where r is the radius and x is the measure of the central angle

Let's substitute the given measures into this equation:

A = πr²(x/360°)

A = (3.14)(12²)(45/360)

Solve:

A = (3.14)(12²)(45/360)

A = (3.14)(144)(45/360)

A = (452.16)(45/360)

A = (452.16)(.125)

A = 56.52

Therefore, the area of the sector is 56.52 units² or 18π units²

The ratio of the length of AC to the length of DC is 1:1.

Divide records A through statistics B to locate your ratio. In the example above, 5/10 = 0.5. Multiply by using the use of a hundred in case you need a percentage. if you want your ratio as a percent, multiply the solution using a hundred.

A ratio is an ordered pair of numbers a and b, written a / b in which b does not exact 0. A percentage is an equation in which ratios are set similarly to each other. As for instance, if there's 1 boy and three women you can write the ratio as 1: three (for every boy there are 3 women).

Answer:

A

Step-by-step explanation:

The completing the square method is important when transforming a quadratic equation to [tex](x - a)^2 =b[/tex] form. The values of a and b are 4 and 3

Given:

[tex]x^2 - 8x + 13 = 0[/tex]

Subtract 13 from both sides

[tex]x^2 - 8x + 13 -13= 0-13[/tex]

[tex]x^2 - 8x= -13[/tex]

-------------------------------------------------------------

Next, we perform the following operations

Take the coefficient (k) of x

[tex]k = -8[/tex]

Divide k by 2

[tex]k/2 = -8/2[/tex]

[tex]k/2 = -4[/tex]

Square both sides

[tex](k/2)^2 = (-4)^2[/tex]

[tex](k/2)^2 = 16[/tex]

Back to the equation, we add 16 to both sides

-------------------------------------------------------------

[tex]x^2 - 8x= -13[/tex]

[tex]x^2 - 8x + 16 = -13 +16[/tex]

[tex]x^2 - 8x + 16 =3[/tex]

Expand the left-hand side

[tex]x^2 - 4x -4x+ 16 =3[/tex]

Factorize

[tex]x(x - 4) -4(x- 4) =3[/tex]

Factor out x -4

[tex](x - 4) (x- 4) =3[/tex]

Express as squares

[tex](x - 4)^2 =3[/tex]

Given that:

[tex](x - a)^2 =b[/tex]

By comparison:

[tex]a =4;\ b =3[/tex]

Have a good day and stay safe <3

Answer:

70% as fraction is 7/10

Step-by-step explanation:

This is the correct answer because if you do 70% by 100% it will be 70/100. If you want it in the simplest form then just write it 7/10. If you don't want the simplest form write 70/100.

These are complementary angles.

If two angles are complementary, then

the sum of their measures is 90°.

Since we know that one of the angles measures 35°, we can find the measure of the other by taking 90 minus the measure of the original angle which in this case is 90 - 35.

So we have 90° - 35° which is 55°

So the measure of the other angle is 55°

Answer:

h(11) = -20 + 11 * 11 = 101

Answer:

h(11)=101

Step-by-step explanation:

This question asks us to find h(11).

Essentially, we need to find h(t) or y, when t, or x, is equal to 11.

h(t)=-20+11t

Therefore, we can substitute 11 in for every t.

h(11)= -20+11(11)

Solve according to PEMDAS( Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)

Multiply 11 and 11 first.

h(11)= -20 +121

Add 121 and -20

h(11)=101

Answer: y=4

Step-by-step explanation:

This is a 45-45-90 triangle. It is also a special triangle. The hypotenuse is x√2. X is sommon through all 3 sides. The legs of the triangle are x in length each.

Looking at the picture, we see the hypotenuse is equal to 4√2. We can set this equal to the hypotenuse to find what x is.

4√2=x√2

x=4

Since we know that the legs of the triangle are both equal to x, we knoe that y=4.

Answer:

9 is the greater x and 2 is the lesser x

Step-by-step explanation:

I really don't know how to explain without simply writing it out for you, which I really can't do. But there's the answer lol

Answer:

x = 2, x = 9

Step-by-step explanation:

Given

x² - 11x + 18 = 0

Consider the factors of the constant term (+ 18) which sum to give the coefficient of the x- term (- 11)

The factors are - 9 and - 2 , since

- 9 × - 2 = + 18 and - 9 - 2 = - 11 , thus

(x - 9)(x - 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 2 = 0 ⇒ x = 2 ← lesser value

x - 9 = 0 ⇒ x = 9 ← greater value

No, if 4 teachers chose 24 students from 1 class to go then the teachers will not be 25% of the passengers.

Step-by-step explanation:

Given: If 4 teachers chose 24 students from 1 class to go then the teachers will be 25% of the passengers.

To find: if the given statement is correct or not

Solution:

Total number of teachers = 4

Total number of students = 24

Total number of passengers = Total number of teachers + Total number of students = 4 + 24 = 28

Here,

25% of Total number of passengers = [tex]\frac{25}{100}(28)=7\neq 4[/tex]

So, if 4 teachers chose 24 students from 1 class to go then the teachers will not be 25% of the passengers.

Answer:

The 99th tower contains 9900 blocks.

Step-by-step explanation:

From the question given, we were told that the nth tower is formed by stacking n blocks on top of an n times n square of blocks. This implies that the number of blocks in n tower will be:

n + n²

Now let us use the diagram to validate the idea.

Tower 1:

n = 1

Number of blocks = 1 + 1² = 2

Tower 2:

Number of blocks = 2 + 2² = 6

Tower 3:

Number of blocks = 3 + 3² = 12

Using same idea, we can obtain the number of blocks in the 99th tower as follow:

Tower 99:

n = 99

Number of blocks = 99 + 99² = 9900

Therefore, the 99th tower contains 9900 blocks.
