Find the values for x and y.

Answer: combine

Step-by-step explanation:

When you combine like terms, it shortens or simplified the equation

Example: 2x-5+15

Combine actual numbers -5 and 15.

2x+10

Answer:

Answer:

23 weeks

Step-by-step explanation:

For 1 week he can learn 2 new pieces. He wants to pay 46 pieces. So we would make the following equation:

[tex]2x=46[/tex] where x is equal to the number of weeks

We can then solve for x by dividing 46 by 2.

[tex]\frac{46}{2} =23[/tex]

So in order for Justin to learn 46 pieces, it would take 23 weeks.

Answer:

A

Step-by-step explanation:

You take the 64 teams, split it in half, and then the exponent is r

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

The equation that represents the number of teams t that remained in the tournament after r rounds is t = 64 x [tex](1/2)^{r}[/tex]

Option A is the correct answer.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example: 3x + 3 = 4 is an equation.

We have,

Number of teams = 64

The number of teams eliminated after each round = Half the team.

The equation represents the number of teams t that remained in the tournament after r rounds.

t = 64 x [tex](1/2)^{r}[/tex] ____(1)

Put r = 1, we must get 32 teams.

t = 64 x 1/2 = 32

Put r = 2 we must get 16 teams.

t = 64 x (1/2)² = 64 x 1/4 = 16

We see that (1) is the correct equation to represent the number of teams t that remained in the tournament after r rounds.

Thus,

The equation that represents the number of teams t that remained in the tournament after r rounds is t = 64 x [tex](1/2)^{r}[/tex]

Option A is the correct answer.

Answer:

a) 10mm each second.

b) 2 in a increasing correlation.

Step-by-step explanation:

a) we want to look at 1 and 2 seconds to recognise the increase.

1 second it reachs 10mm

2seconds it reachs 20mm

20mm-10mm=10mm

This means each second its increasing by 10mm

B) Rise / Run

our two coordinates will be (1,10) and (2,20)

the run is when it goes across, which will be 1

and the rise will be 2

The answer is 73 and 42

Step-by-step explanation:

1. Subtracting 21 from 115 which gives you 94, but that wouldn't be the answer because its asking for two numbers with a difference.

2. From you subtract 21 from 94 which is 73, next subract 73 from 115 which gives you 42.

Answer:

[tex]\displaystyle y=\frac{1}{4}x+\frac{1}{4}[/tex]

Step-by-step explanation:

We want to find the equation of the line that passes through the point (-1, 0) and have the slope 1/4.

We can use the point-slope form given by:

[tex]\displaystyle y-y_1=m(x-x_1)[/tex]

We will substitute (-1, 0) for (x₁, y₁) and 1/4 for the slope m. Therefore:

[tex]\displaystyle y-(0)=\frac{1}{4}(x-(-1))[/tex]

Simplify:

[tex]\displaystyle y=\frac{1}{4}(x+1)[/tex]

Distribute. Thus, our equation is:

[tex]\displaystyle y=\frac{1}{4}x+\frac{1}{4}[/tex]

Answer:

The area of the cone is "1,695.6 cm³".

Step-by-step explanation:

The given values are:

Diameter of cone,

d = 18 cm

then,

Radius,

r = [tex]\frac{d}{2}[/tex]

 = [tex]\frac{18}{2}[/tex]

 = [tex]9 \ cm[/tex]

Height,

h = 20 cm

As we know,

⇒  Area of a cone = [tex]\frac{1}{3} \pi r^2 h[/tex]

On substituting the given values in the above formula, we get

⇒                            = [tex]\frac{1}{3}\times 3.14\times (9)^2\times 20[/tex]

⇒                            = [tex]\frac{1}{3}\times 3.14\times 81\times 20[/tex]

⇒                            = [tex]3.14\times 27\times 20[/tex]

⇒                            = [tex]1,695.6 \ cm^3[/tex]

Answer:

n = 14

Step-by-step explanation:

Width of the given right angles triangle = (n + 6) cm

Since, height of this triangle is 10 cm less than the width.

Height = (n + 6) - 10

         = (n - 4) cm

Area of a right angles triangle = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

                                                  = [tex]\frac{1}{2}(n+6)(n-4)[/tex]

100 = [tex]\frac{1}{2}(n+6)(n -4)[/tex]

200 = n(n - 4) + 6(n -4)

200 = n² - 4n + 6n - 24

200 = n² + 2n - 24

n² + 2n - 224 = 0

n² + 16n - 14n - 224 = 0

n(n + 16) - 14(n + 16) = 0

(n + 16)(n - 14) = 0

n = -16, 14

Since n = -16 is an extraneous solution, so the answer is n = 14.
