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!

Leo has a lock box with a volume of 312 cubic inches. The box is 4 inches high and 13 inches long. What is the width of the box?
natima [27]

Answer:

6in

Step-by-step explanation:

Given data

Volume of the lockbox= 312 cubic inches

Height= 4in

Length= 13in

Width= ???

The expression for the volume of box is

V= L*W*H

substitute

312=13*W*4

312=52W

W= 312/52

W=6 in

Hence the width is 6in

The first term of an arithmetic sequence is 4 and the tenth term is 67.
serg [7]

Answer:

d = 7

Step-by-step explanation:

The nth term of an arithmetic sequence is

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Give a₁₀ = 67 and a₁ = 4 , then

a₁ + 9d = 67

4 + 9d = 67 ( subtract 4 from both sides )

9d = 63 ( divide both sides by 9 )

d = 7

Given the diagram below, what is m/B?
Radda [10]

Answer:

115°

Step-by-step explanation:

The above shape is a quadrilateral.

A quadrilateral is a closed shape and a type of polygon that has four sides, four vertices and four angles.

The sum of interior angles of a Quadrilateral is 360°

Therefore,

115 + 65 + 65 + m = 360

245 + m = 360

m = 360 - 245

m = 115°

Therefore, m< B = 115°
