Step-by-step explanation:

[tex]360 = 60 + 4x \\ 360 - 60 = 4x \\ 300 = 4x \\ \frac{300}{4} = \frac{4x}{4} \\ x = 75[/tex]

The total internal angle of the polygon is 360°. Since there are 4 unknown angles but the same, we would just add all those to 60° to equal a full 360°.

I hope this helped if wrong I'm not sure what the answer is

Answer: x = 3

Step-by-step explanation: First subtract 2x from both sides to get:

3x + 6 = 15

Then subtract 6 on both sides

3x = 9

Now divide by 3 to isolate x to get...

x = 3

ಠ_ಠ༼ つ ◕_◕ ༽つ☜(ﾟヮﾟ☜)(☞ﾟヮﾟ)☞(•_•)(┬┬﹏┬┬)

Answer:

Step 1:

Start by setting it up with the divisor 9 on the left side and the dividend 25 on the right side like this:

   9 ⟌ 2 5  

Step 2:

The divisor (9) goes into the first digit of the dividend (2), 0 time(s). Therefore, put 0 on top:

       0    

   9 ⟌ 2 5  

Step 3:

Multiply the divisor by the result in the previous step (9 x 0 = 0) and write that answer below the dividend.

       0    

   9 ⟌ 2 5  

       0    

Step 4:

Subtract the result in the previous step from the first digit of the dividend (2 - 0 = 2) and write the answer below.

       0    

   9 ⟌ 2 5  

     - 0    

       2    

Step 5:

Move down the 2nd digit of the dividend (5) like this:

       0    

   9 ⟌ 2 5  

     - 0    

       2 5  

Step 6:

The divisor (9) goes into the bottom number (25), 2 time(s). Therefore, put 2 on top:

       0 2  

   9 ⟌ 2 5  

     - 0    

       2 5  

Step 7:

Multiply the divisor by the result in the previous step (9 x 2 = 18) and write that answer at the bottom:

       0 2  

   9 ⟌ 2 5  

     - 0    

       2 5  

      1 8  

Step 8:

Subtract the result in the previous step from the number written above it. (25 - 18 = 7) and write the answer at the bottom.

       0 2  

   9 ⟌ 2 5  

     - 0    

       2 5  

     - 1 8

[tex]2x^{2}[/tex]-x

Step-by-step explanation:

To find (x+1) substitue x+1 into the function.

1. 2(x+1)^2-5(x+1)+3: Substitution

2. 2x^2+4x+2-5x+5+3: First do binominal expansion theorem for 1st one then distrubtive property for the first and second one.

3.Combine like with like

[tex]2x^{2}[/tex] , 4x+(-5x)= -x,  2-5+3=0 so

Answer:

8 trips.

Step-by-step explanation:

15 + 1.50 = 16.50

16.50 divided by 2 = 8.25

Answer:

x-8= -3x+12

adding 8 and 3x on both sides

x-8+8+3x= -3x+3x+12+8

x+3x=20

4x=20 divide by 4

x=5

x+12= -x-6

adding x and subtacating 12 on both sides

x+x+12-12= -x+x-6-12

2x = -18 divide by 2

x= -9

Answer:

x^2-3x-6

Step-by-step explanation:

Answer:

The correct answer is:

Option 2: Yes, because the slopes of lines are negative reciprocals.

Step-by-step explanation:

Given equations of lines are:

Line p: x+2y=1

Line q: y=2x+1

We can determine if two lines are parallel or perpendicular by comparing the slopes of line.

Slope intercept form of line is given by the formula

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

Equation of line q is already in slope intercept form.

We have to convert the equation of line p in slope-intercept form

[tex]x+2y = 1\\2y = -x+1\\2y = -\frac{1}{2}x+\frac{1}{2}[/tex]

Slope of line p = 2

Slope of line q = -1/2

We can see that

[tex]2.-\frac{1}{2} = -1[/tex]

The product of slopes of both lines is -1, hence, the lines are perpendicular.

Hence,

The correct answer is:

Option 2: Yes, because the slopes of lines are negative reciprocals.

Answer:

11/15

Step-by-step explanation:

There are 15 jellies in a box and 11 of them are not red so your answer should be 11/15.

The given equations are  

12x + 4y = 152 ...........1

32x + 12y = 420 .....2

Multiplying equation 1 by 3 to make  coefficient of y same we have:

36x+12y= 456

32x+12y=420

Subtracting the two equations we have:

4x=36.

Dividing by 4 both sides  

x= 9.

Substituting x value in equation 1

12(9) + 4y = 152

108+4y=152

Subtracting 108 both sides: 4y=44.

Dividing both sides by 4.

y=11.

Answer:

C. The IQR is the best measurement of spread for games and movies

Step-by-step explanation:

In a box plot, the Interquartile Range (IQR) can be gotten by finding the range of the rectangular box. That is, The third Quartile (Q3) - the first quartile (Q1).

The IQR is a measure of spread, and it would be appropriate for measuring spread of the data for both Movies and Basketball games displayed by the box plot.

Answer:

C

Step-by-step explanation:

Answer:

The correct option is (c).

Step-by-step explanation:

Let x and y denote the cost of game 1 and game 2 respectively.

ATQ,

4x+6y = 18  ....(1)

5x + 5y = 20 ....(2)

Multiply equation (1) by 5 and equation (2) by 4.

20x+30y = 90 ....(3)

20x + 20y = 80 ....(4)

Subtracting equation (3) and (4)

20x+30y - (20x + 20y) = 90-80

20x-20x+30y-20y = 10

10y = 10

y = 1

Put the value of y in equation (1).

4x+6(1) = 18

4x = 18-6

4x = 12

x = 3

Hence, the cost of game 1 is $3.00
