Answer:

−30a−6

Step-by-step explanation:

Let's simplify step-by-step.

−9a−10−6a+7−9a−10−6a+7

=−9a+−10+−6a+7+−9a+−10+−6a+7

Combine Like Terms:

=−9a+−10+−6a+7+−9a+−10+−6a+7

=(−9a+−6a+−9a+−6a)+(−10+7+−10+7)

=−30a+−6

A student counted the number of times her teacher said word like during her class over an 11- day period [likes per class period
hichkok12 [17]
Let us calculate the median; the 6th observation is 20, so it is 20. We need the 6th observation so that out of the 11 observations we have 5 above the median and 5 below (or equal). We also have that then Q1 is the median of the lowest 5 observations, hence 19 (14,16,19,19,20, the 3rd observation is 19). Similarly, we get that the median for the upper half of the observations, Q3 namely, is 22 (21,21,22,22,23, the 3rd observation is 22). Thus, the interquartile range is 3=Q3-Q1. According to our calculations, all observations are wrong.

Can anyone be nice and help a girl out. please i need help.
Nuetrik [128]

Answer:

Step-by-step explanation:

So when we solve the inequality:

2(x - 2) >_ 2

x - 2 >_  1 (divided 2 from both sides)

x >_ 3 (added 2 to both sides)

So with our final equation, we can work out that the answer is b, but d is also correct so I'm assuming that the inequality needs to be represented on a number line as hey usually are.

Hope this helps,

If you use your office computer 40 hours per week, and do not unplug the computer when it is not in use, how much carbon dioxide
dangina [55]
If you use a laptop:  9.25; a desktop with a CRT monitor:  55.51; a desktop with an LCD monitor:  46.26.

A laptop that is plugged up and turned off uses 0.001kw/hr of energy.  Each kwh of energy produces, on average, 1.39 lbs of CO2.  There are 24*7=168 hours in the week; subtract the 40 hour work week from this and we have 128 hours a week for 52 weeks a year:
0.001*128*52=6.656*1.39=9.25.

A desktop that is plugged up and turned off uses 0.004kw/hr of energy.  A CRT monitor uses 0.002 kw/hr when turned off.  This means we have:
(0.004*128*52*1.39)+(0.002*128*52*1.39)=55.51.

For a desktop and an LCD monitor, which uses 0.001 kw/hr of energy, we have:
(0.004*128*52*139)+(0.001*128*52*1.39)=46.26.

The bigger of two numbers is four more
Otrada [13]

Answer:

X=the smaller

y=the larger

The bigger of two numbers is four more than the smaller, then:

y=x+4

one more than twice the smaller is the same as the larger, then

1+2x=y

We have the following system of equations:

y=x+4

y=2x+1

We solve this system by equal values method:

x+4=2x+1

x-2x=1-4

-x=-3

x=3

We find the value of "y"now:

y=x+4

y=3+4

y=7

the values of x and y are:

x=3

y=7
