In a certain year, the difference between Mary’s and Jim’s annual salaries was twice the difference between Mary’s and Kate’s an

N76 [4]

Answer: Average annual salary of the 3 people is equal to Kate's annual salary.

Step-by-step explanation:

Since we have given that

Difference between Mary's and Jim's annual salaries be m-j

Difference between Mary's and Kate's annual salaries be m-k

According to question, we get that

$m-j=2(m-k)\\\\m-j=2m-2k\\\\2k-j=2m\\\\2k-j=m$

Average annual salary of the 3 people would be

$\dfrac{m+k+j}{3}\\\\=\dfrac{2k-j+j+k}{3}\\\\=\dfrac{3k}{3}\\\\=k$

Hence, average annual salary of the 3 people is equal to Kate's annual salary.

9) Solve by the elimination method.<br><br> x + y = -5<br> x - y = 11

vlabodo [156]

<h2><u>Answer:</u></h2>

x = 3

y = -8

<h2><u>Step-by-step explanation:</u></h2>

x + y = -5

x - y = 11

Since the y's will cancel out, we don't need to modify the two equations in any way.

Now, just add the two equations.

x + x = 2x

y + (-y) = 0

-5 + 11 = 6

2x = 6

Divide by 2.

x = 3

To find y, plug 3 in as "x" in one of the two equations.

3 + y = -5

y = -8
