Aleksandr-060686 [28]

Answer: 7%

Step-by-step explanation:

Given: Initial jobs = 428.5 thousand

Average rate of declining of jobs from 2010 to 2020 = 3 thousand jobs per year

From 2010 to 2020 , there are 10 years.

Total jobs declines till 2020 = 10 x (3 thousand)

= 30 thousand (Change in jobs)

Now, utilities percent change for 2010 to 2020 : $\dfrac{change \ in \ job\ numbers}{Initial\ jobs}\times 100$

$=\dfrac{30}{428.5}\times100\\\\\approx7.00\%$

Utilities percent change for 2010 to 2020 = 7 %

-1/9+-5/9=<br> Simplest form<br> 24 points

Nataly [62]

-1/9+-5/9=

When you are adding a negative number, the operation turns into subtraction:

-1/9-5/9= $\frac{-1-5}{9}$ $=-\frac{6}{9}=-\frac{2}{3}$

Really, it's just subtraction. The simplest form is -2/3, which is equal to -0.66667.

I hope this helps :)
