Answer:

x = 26, y = 9

Step-by-step explanation:

Add the bottom equations and set them equal to 180

8x -28 = 180

8x = 208 divide each by 8

x = 26

Find the bottom right, 3(26) - 11

78 - 11 = 67

The unlabeled top left box is also equal to 67 degrees.

So 2y + 5 = 23

2y = 18

y = 9

Answer:

The answer is x = 26 and y = 31.

Step-by-step explanation:

To solve this problem, we should first solve for the value of x.  Since the angles that measure (5x-17) and (3x-11) are supplementary, this means that they must add up to 180 degrees.  This allows us to make the following equation:

(5x - 17) + (3x-11) = 180

When we combine like terms on the left side of the equation, we get:

8x - 28 = 180

Then, we can add 28 to both sides.

8x = 208

Finally, we can divide both sides by 8 to get x alone on the left side of the equation.

x = 26

Now that we know our value for x, we must find our value for y.  To do this, we should notice that the angle 3x-11 has a vertical angle (an angle that is directly across from it).  By the definition of vertical angles, this angle must have the same measure, meaning it will also have the value 3x - 11.  This vertical angle is complementary to the angle 2y + 5, which means that their sum must equal 90 degrees; therefore, we can make the following equation:

3x - 11 = 2y + 5

Since we found our value of x already in the above equation, we can substitute this value into this equation:

3(26) - 11 = 2y + 5

Next, we can perform the multiplication on the left side of the equation.

78 - 11 = 2y + 5

Then, we can perform the subtraction on the left side of the equation.

67 = 2y + 5

Next, we should subtract 5 from both sides of the equation.

62 = 2y

Finally, we should divide both sides of the equation by 2 to get the variable y by itself on the right side of the equation.

y = 31

Therefore, the answer to this problem is x = 26 and y = 31.

Hope this helps!

What is the slope of a line is parallel to y=(1/2)x=3
aniked [119]
Hi there! The answer is (1/2)

I suppose you mean the slope of a line that is parallel to y = (1/2)x + 3.

This equation is written in slope-intercept form, which means that the number in front of x represents the slope of the line. The other number represents the y-intercept.

A line that is parallel to another line, will be a line with the same slope. Since the slope of y = (1/2)x + 3 is (1/2), the slope of a line parallel to this line is (1/2) as well.

~ Hope this helps you!

Identify the probability to the nearest hundredth that a point chosen randomly inside the rectangle is in the triangle. HELP PLE
sashaice [31]

Answer:

0.02

Step-by-step explanation:

we know that

The probability that a point chosen randomly inside the rectangle is in the triangle is equal to divide the area of the triangle by the area of rectangle

Let

x-----> the area of triangle

y----> the area of rectangle

P -----> the probability

P=x/y

<em>Find the area of triangle (x)</em>

A=(1/2)(5)(2)=5\ in^{2}

<em>Find the area of rectangle (y)</em>

A=18*12=216\ in^{2}

<em>Find the probability P</em>

P=5/216=0.02
