Answer:

x=-4

Step-by-step explanation:

Start by distributing the -3 to both x and 2 (This is called the distributive property)

After using the distributive property your equation should look like this:

6=-3x-6

Now add 6 to both sides! Your equation should now look like this:

12=-3x

Now divide both sides by -3! Your equation should now look like this:

-4=x

You can rearrange -4=x to x=-4 as your final answer!

A large restaurant chain wanted to determine if its employees were taking sick days on some days of the week more than others. T
lidiya [134]

Answer:

0.2

Step-by-step explanation:

Given the data :

Day : Mon Tue Wed Thu Fri Sat Sun

# of sick days 22 11 16 17 21 28 25

The expected count of sick days taken on Saturday is obtained thus :

Expected count = (row total * column total) / overall total

Here, the table is just one way :

Hence, we use :

Observed value / total days

Hence,

Expected count on Saturday = sick days on Saturday / total sick days

Expected count on Saturday = 28 / (22+11+16+17+21+28+25)

Expected count on Saturday = 28 / 140

= 0.2

Laila is 14 years older than tom. Laila is 5 years younger than Dan. Altogether they have a combined age of 51. How old are they
notka56 [123]
Laila=l
Tom=t
Dan=d

l=t+14
l=d-5
l+t+d=51

In terms of l:
d=l+5
t=l-14

So:
l+l+5+l-14=51
3l+5-14=51
3l-9=51
3l=60
l=20
d=25
t=6

Hope this helps :)
