Answer: x=−10

Step-by-step explanation:

x−3−2(x+6)=−5

x+−3+(−2)(x)+(−2)(6)=−5(Distribute)

x+−3+−2x+−12=−5

(x+−2x)+(−3+−12)=−5(Combine Like Terms)

−x+−15=−5

−x−15=−5

−x−15+15=−5+15

−x=10

Suppose the average yearly salary of an individual whose final degree is a master's is $41 thousand less than twice that of an

charle [14.2K]

Answer:

The average salary of master's degree people is $ 63,000 And

The average salary of bachelor's degree people is $ 52,000

Step-by-step explanation:

Given in question as :

Let the average salary of master's degree people = $ M And

Let the average salary of bachelor's degree people = $ B

According to question ,

The average salary of master's degree people + The average salary of bachelor's degree people = $115,000

Or , $ M + $ B = $ 115,000 ............. A

Again ,

$ M = 2 × $ B - $ 41,000 ............... B

From eq A and eq B

(2 × $ B - $ 41,000 ) + ( $ B ) = $ 115,000

Or, 3×$ B = 156,000

∴ B = $\frac{156,000}{3}$ = $ 52,000

And M = $ 115,000 - $ 52,000

∴ M = $ 63,000

Hence The average salary of master's degree people is $ 63,000 And

The average salary of bachelor's degree people is $ 52,000 Answer

107 = 7 - 2(7b - 1) what does b equal?

topjm [15]

107 = 7 -2 (7b - 1)

First, distribute -2 to all terms within the parenthesis

-2(7b - 1) = -14b + 2

107 = 7 -14b + 2

Combine like terms

107 = -14b (+7 + 2)

107 = -14b + 9

Isolate the b. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

Subtract 9 from both sides

107 (-9) = -14b + 9 (-9)

107 - 9 = -14b

98 = -14b

Isolate the b. Divide -14 from both sides

(98)/-14 = (-14b)/-14

98/-14 = b

b = −7

-7 is your answer

hope this helps
