Complete question :

Suppose the average yearly salary of an individual whose final degree is a master's is $55 thousand less than twice that of an individual whose final degree is a bachelor's. Combined, two people with each of these educational attainments earn ?$116 thousand. Find the average yearly salary of an individual with each of these final degrees.

Answer:

Average salary of a bachelor's degree holder = $57,000

Average salary of a master's degree holder = $59,000

Step-by-step explanation:

Let:

Average salary of a bachelor's degree = b

Salary of a master's holder = 2b - 55000

Combined salary of both degrees :

b + (2b - 55000) = 116000

b + 2b - 55000 = 116000

3b = 116000 + 55000

3b = 171000

Divide both sides by 3

3b/3 = 171000/3

b = 57000

Hence,

Average salary of a bachelor's degree holder = $57,000

Average salary of a master's degree holder = 2(57000) - 55000 = 59,000

Answer:

72

Step-by-step explanation:

Call the amount she started with, x

she removes 2

x - 2

then she divides it by 10

(x - 2)/10

each bag contains 7 pieces

(x - 2)/10 = 7

so now solve using inverse operations

(x - 2)/10 = 7

        *10    *10

x - 2 = 70

  +2    +2

x = 72

Option A= 36 + 27 pi is the correct answer

Area of square= 6*6 = 36

Area of the remaining circle = 3/4*pi*r^2

= 3/4*pi*6^2= 27*pi

Thus, total area = area of square+ area of circle

36 + 27pi

Answer: X= -3

Step-by-step explanation:

First you would subtract 8 from both sides so you have...

Simplify...

-3x=9

Divide by -3 to get

x= 9/-3

x= -3

Answer:

[tex]\boxed {x = -2}[/tex]

Step-by-step explanation:

Solve for the value of [tex]x[/tex]:

[tex]-5x - 4 = 3x + 12[/tex]

-Take [tex]3x[/tex] and subtract it from [tex]-5x[/tex]:

[tex]-5x - 4 - 3x = 3x - 3x + 12[/tex]

[tex]-8x - 4 = 12[/tex]

-Add [tex]4[/tex] to both sides:

[tex]-8x - 4 + 4 = 12 + 4[/tex]

[tex]-8x = 16[/tex]

-Divide both sides by [tex]-8[/tex]:

[tex]\frac{-8x}{-8} = \frac{16}{-8}[/tex]

[tex]\boxed {x = -2}[/tex]

Therefore, the value of [tex]x[/tex] is [tex]-2[/tex].

Answer:  The perimeter of triangle ABC is 12 1/2 inches.

Step-by-step explanation:  Each radius given is used twice in the diagram to connect to the radii of the adjacent circles to form the sides of the triangle.

So the perimeter of the triangle is found by adding twice the length of each radius.

P= 2( 2 + 3 1/4 + 1)

P= 2( 6 1/4)

P = 12 1/2

Answer:

9 more shots

Step-by-step explanation:

If the first golfer had a score of +6 and the second golfer had a score of -3, in order to know how many more shots the first golfer take, we will take the difference between both goals as shown;

= 6-(-3)

= 6+3

= 9

Hence the first golfer took 9 more shots than the second.

Step-by-step explanation:

0.75 yard = 1 costume

1 yard = 1/0.75 =4/3 costume

6 yards = 4/3 × 6 = 8 costumes

if you wanna check,

8 costumes = 6 yards

1 costume = 6/ 8

= 3/4 (0.75) yard

Answer: 15/17

Step-by-step explanation: I took the K12 Math test!

Based on the trigonometric calculations, the value of cosC is equal to: C. 15/17.

In Mathematics, there are six (6) types of trigonometry graph that are used to graphically represent a trigonometric function and these include:

Based on the right-angled triangle attached, we can deduce the following parameters:

Opposite side (BA) = 8 units.

Adjacent side (BC) = 15 units.

Hypotenuse (AC) = 17 units.

In trigonometry, cosine (cos) is given by this mathematical expression:

cosC = BC/AC

cosC = 15/17.

Step-by-step explanation:

Answer:

-7/2 is the slope. -10.5 is your starting point on the y-axis. You go from -10.5, up 7 and over to the left 2 times because it's negative.

Step-by-step explanation:

-7x-2y=-21

-2y=7x-21

y=-7/2x-21/2

y=-7/2x-10.5

Hope this helps!

You might want to simplify the equation first. Basically, we'll use y = ax+b instead.

[tex]-7x-2y=-21\\-2y=-21+7x\\y=\frac{-21}{-2}+\frac{7x}{-2} \\y=\frac{21}{2}-\frac{7x}{2}\\y=\frac{21-7x}{2}[/tex]

Should have been like this then you are able to graph.

To graph, you need to find the x-intercept and y-intercept.

(1) Find x-intercept, substitute y = 0

[tex]0=\frac{21-7x}{2} \\0=21-7x\\7x=21\\x=3[/tex]

Thus, the graph has a x-intercept at (3,0). For those who are wondering where does the fractional 2 go, just multiply the whole equation by 2 to get rid of the fraction.

(2) Find y-intercept, substitute x = 0

[tex]y=\frac{21-7x}{2}\\ y=\frac{21-0}{2}\\ y=\frac{21}{2} \\[/tex]

Also 21/2 = 10.5, Thus the graph passes y-axis at (0, 10.5)

Now plot the graph, make a line from x-intercept and y-intercept and you should get like this (Picture below.)
