3(5x-2)+3x

Distribute 3 into the parathesis: 15x-6+3x

Combine like terms: 18x-6

Your final answer is 18x-6

Answer:

The triangles formed are iscocleles triangles making their bases the same angle measures. Additionally, RST anf RGT are congruent since they are each equal to 1/2 of RQTS

We also know that the interior angles of any triangle add up to 180°

Therefore,

m<R + m<T + 126 = 180

m<R + m<T = 54

Since m<R and m<T are equal, R and T must be equal to 27

m<R=27

m<t=27

Therefore,

m<1=27

m<2=27

m<3=27

m<4=27

m<5=126

Answer:

10 hours, $84

Step-by-step explanation:

System of equations is:

7x+14=y

8.4x=y

Substitute to get:

7x+14=8.4x

subtract 7x from both sides

14=1.4x

x=10

So they will have to have worked for 10 hours

8.4*10=y

84=y

So they will have earned 84 dollars each

x=10 y=84

Answer:

BC = [tex] 1.8 [/tex]

Step-by-step explanation:

∆ABC is an equilateral ∆ because all three angles are equal. Therefore, all its sides would be equal also. This means AB = BC = AC

Thus, let's find the value of x.

[tex] \frac{7}{4}x - 1 = \frac{9}{3}x - 3 [/tex]

Collect like terms

[tex] \frac{7}{4}x - \frac{9}{3}x = 1 - 3 [/tex]

[tex] \frac{7x}{4} - 3x = -2 [/tex]

[tex] \frac{7x - 12x}{4} = -2 [/tex]

[tex] \frac{-5x}{4} = -2 [/tex]

Multiply both sides by 4

[tex] \frac{-5x}{4}*4 = -2*4 [/tex]

[tex] -5x = -8 [/tex]

Divide both sides by -5

[tex] x = \frac{8}{5} [/tex]

AB = BC = AC

Therefore,

BC = [tex] \frac{7}{4}x - 1 [/tex]

Plug in the value of x

BC = [tex] \frac{7}{4}*\frac{8}{5} - 1 [/tex]

BC = [tex] \frac{56}{20} - 1 [/tex]

BC = [tex] 2.8 - 1 [/tex]

BC = [tex] 1.8 [/tex]

Answer:

5

Step-by-step explanation:

this is basic algebra so it's important to understand this concept now. you need to combine like terms so 3x-6=9 becomes 3x=15 (you add the 6 to add like terms). You then divide the 3 from 3x on both sides to get x=5

The value of x makes the equation 3x - 6 = 9 true is: x = 5.

Here, we have,

given that,

the equation is: 3x - 6 = 9

so have,

3x-6=9

We need to combine like terms

=> 3x = 9 + 6

(we add the 6 to add like terms).

becomes, => 3x=15

we then divide the 3 from on both sides

=> 3x/3 = 15/3

we get

=> x=5

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

We have to given that;

The figure is shown in image.

Since, We know that;

Wavelength is the distance between identical points in the adjacent cycles of a waveform signal propagated in space or along a wire.

Hence, We get;

The wavelength measurement of the figure is,

Answer:

the answer is A substitution

Given:

The table of score and frequency.

To find:

The probability that on the next roll the score will be 4.

Solution:

From the given table it is clear that the score 4 occurs 10 times.

Number of times the dice was rolled = 17 + 24 + 23 + 10 + 16 + 30

                                                             = 120

The probability that on the next roll the score will be 4 is

[tex]\text{Required probability}=\dfrac{\text{Number of times 4 occurs}}{\text{Number of times the dice was rolled}}[/tex]

[tex]\text{Required probability}=\dfrac{10}{120}[/tex]

[tex]\text{Required probability}=\dfrac{1}{12}[/tex]

Therefore, the required probability is [tex]\dfrac{1}{12}[/tex].

Answer:

(4, 18)

Step-by-step explanation:

We can just pluck the x values into the equation: y = 5x -1 to see if the y values fit.

1. y = 5(4) - 1

     = 20 - 1

     = 19 (Nope, 18 is not 19)

2. y = 5(3) - 1

      = 15 - 1

      = 14 (Yep, same as option)

3. y = 5(0) - 1

      = 0-1

      = -1 (Yep, same as option)

4. y = 5(2) - 1

      = 10 - 1

      = 9 (Yep, same as option)

The point (4, 18) is not lies on the given line.

First option is correct.

The equation of line in slope intercept form is,

                              [tex]y=mx+c[/tex]

Where m is slope and c is y intercept.

Given that, m = 5 and c = -1

Substitute above values

Equation of line is,

                         [tex]y=5x-1[/tex]

Substitute first option (4, 18) in equation of line.

                     [tex]18=5(4)-1\\\\18=20-1\\\\18=19[/tex], which is invalid equation.

Hence, point (4, 18) is not lies on the given line.

Answer:

12

Step-by-step explanation:

Answer:

Monthly charges = $70

Intuition charges = $2710

Step-by-step explanation:

There is intuition fee and per month fee for joining the Pine River country club.

Total cost for 7 months is $3200

Total cost for one and a half years is $3970

one and a half years means 18 months.

To find:

Intuition fee and monthly dues?

Solution:

Let the intuition fee = [tex]i[/tex]

Let the monthly dues = [tex]m[/tex]

Total cost for 7 months can be represented as

[tex]i+7m = 3200[/tex] ..... (1)

Total cost for 18 months can be represented as

[tex]i+18m = 3970 .... (2)[/tex]

Here, we have 2 equations and 2 variables whose values are to be found.

Let us use elimination method to solve the equations.

Subtracting equation (1) from (2):

[tex]11m = 770\\\Rightarrow m = 70[/tex]

Therefore, the monthly dues are $70.

Using equation (1), we can find the value of [tex]i[/tex].

[tex]i + 70\times 7 = 3200\\\Rightarrow i = 3200 - 490\\\Rightarrow i = \$2710[/tex]

Therefore, intuition charges are $2710.
