How Do I Find X In These Equations

Answers

Answer 1

Answers:

Problem 9) x = 1Problem 10) x = 3Problem 11) x = 12Problem 12) x = 12

==============================================

Explanation:

For problems 9 through 12, we'll use the same set of steps. Recall that any parallelogram has the property that the adjacent angles are supplementary. This means close by angles add to 180. Each of the four diagrams show pairs of adjacent angles.

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

In problem 9, we have the following steps

(79x-1) + (102) = 180

79x + 101 = 180

79x = 180-101

79x = 79

x = 79/79

x = 1

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

Problem 10 is the same idea

(85) + (30x+5) = 180

30x+90 = 180

30x = 180-90

30x = 90

x = 90/30

x = 3

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

Problem 11

(55)+(9x+17) = 180

9x+72 = 180

9x = 180-72

9x = 108

x = 108/9

x = 12

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

Problem 12

(3x+12)+(132) = 180

3x+144 = 180

3x = 180-144

3x = 36

x = 36/3

x = 12

Answer 2

Answer:

9. X = 1

10. X = 3

11. X = 12

12. X = 12

Step-by-step explanation:

9.

1) 79x - 1 + 102 = 180

2) 79x + 101 = 180

3) Subtract 101 from both sides

4) 79x = 79

5) x = 1

10.

1) 85 + 30x + 5 = 180

2) 30x + 90 = 180

3) Subtract 90 from both sides

4) 30x = 90

5) x = 3

11.

1) 55 + 9x + 17 = 180

2) 9x + 72 = 180

3) Subtract 72 from both sides

3) 9x = 108

4) X = 12

12.

1) 3x + 12 + 132  = 180

2) 3x + 144 = 180

3) Subtract 144 from both sides

4) 3x = 36

5) x = 12

All answers have been checked by plugging the X back into the equation.

2. A(x)=2x^2+8x+14

Answers

Step-by-step explanation:

These aren't a perfect square bec. 1 st and 3rd terms must be perfect square

Which is the graph of the linear inequality x – 2y > –6?

Answers

Answer:

uhhh d????

Step-by-step explanation:

Graph D represents the  linear inequality x – 2y > –6.

The given inequality is x – 2y > –6.

We rearrange the inequality as y < (1/2)x + 3

Now we have the inequality in slope-intercept form, y < mx + b, where m is the slope (1/2) and b is the y-intercept (3).

To graph this inequality, you can start by plotting the y-intercept, which is the point (0, 3).

The slope of the graph is 1/2.

However, the inequality is y < (1/2)x + 3, which means the shaded region is below the line.

Hence, graph D represents the  linear inequality x – 2y > –6.

Kiran paid $54.00 for 3 tickets to go to a corn maze. At the same rate, what is the cost of 5 tickets to the maze? *

Answers

Answer:90

Step-by-step explanation:

Answer: $90

Step-by-step explanation:

You can set up a proportion.

$54 = 3 tickets

x = 5 tickets

To find x, multiply 54 and 5.

54 × 5 = 270

Then divide 270 by 3.

270 ÷ 3 = $90

Since we figured out x = $90, this means that it costs $90 for 5 tickets.

Reagan and Nathan are 40 miles apart on a bike trail when they start pedaling toward each other on their b bicycles. Reagan rides at a constant speed of 8 miles per hour, and Nathan rides a constant speed of 10 miles per hour. How long does it take until Reagan and Nathan meet?

Answers

Answer:

They meet in 2.22 hours.

Step-by-step explanation:

We can find the time at which Reagan and Nathan meet by equaling the time as follows:

[tex] v_{R} = \frac{x_{R}}{t} [/tex]  

[tex] x_{R} = v_{R}t [/tex]    (1)      

[tex] v_{N} = \frac{x_{N}}{t} [/tex]  

[tex] x_{N} = v_{N}t [/tex]   (2)

Where R is for Reagan and N for Nathan.

Knowing that:

[tex] x_{R} + x_{N} = 40 mi [/tex]

By adding equations (1) and (2) we have:

[tex] x_{R} + x_{N} = v_{R}t + v_{N}t [/tex]

[tex] t = \frac{x_{R} + x_{N}}{|v_{R}| + |v_{N}|} = \frac{40 mi}{8 mi/h + 10 mi/h} = 2.22 h [/tex]

Therefore, they meet in 2.22 hours.        

I hope it helps you!

Proportional and linear functions are almost identical in form. The only difference is the addition of the “b” constant to the linear function. Indeed, a proportional relationship is just a linear relationship where b = 0, or to put it another way, where the line passes through the origin (0,0).

2) The correct option is;

A. AA Similarity Postulate

Step-by-step explanation:

1) Please find attached the given plot and sketch of the points created with Microsoft Word

2) The given parameters are;

The coordinates of the points are A(0, 0), B(1, 0), C(1, 2), D(2, 0) and E(2, 4)

Therefore, we have;

The length of segment AB = 1

The length of segment BC = 2

The length of segment AD = 2

The length of segment DE = 4

Therefore, we have;

∠ABC = ∠ADE = 90°

∠BAC = = artctan(2/1) = ∠DAE = artctan(4/2) = 63.435°

Therefore, ΔABC and ΔADE are similar by AA Similarity Postulate
