In place of x you keep 6 and in place of y you keep -2

(6,-2) is true for 4x-3y=30 but NOT for 3x+2y=22.

4*6=24

3*(-2)=-6

24-(-6) changes to 24+6 which equals 30

24+6=30.

3*6=18

2*(-2)=-4

18+(-4) would be changed to 18-4

18-4=14

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

Verdich [7]

Answer:

Step-by-step explanation:

Let the 5 digit palindrome formed from 1,2,3,4,5 be represented as XYZXY

Possible outcomes of X are 1,2,3 which give 3 possible outcomes

Possible outcomes of Y are 1,2,3 which also gives 3 possible outcomes

Possible outcomes of Z are 1,2,3 which will give 3 possible outcomes.

The total possible outcome = 3*3*3

= 27
