Answer:

163

Step-by-step explanation:

180 is the sum of all degrees.

subtract 22 from that to get 158

so X-5 = 158

you add a 5 to both sides: X+5-5=158+5

you cancel the fives in the first side of the equation and add 5 to 158 on the other side.

X=158+5

X=163

What is the answer? Y=x-6 and y=2x

Rashid [163]

$\begin{cases}y=x-6\\y=2x\end{cases}\implies~x-6=2x\implies~x=-6$

which means

$y=x-6=y=-6-6=-12$

3x = 1 ( multiply both sides by 10 )

30x = 10 → (a)

Mr. Bennet owns 4 restaurants. The mean number of tables is 30. What could happen to the mean if he buys two new restaurants, on

wariber [46]

Answer:

Final mean value = 24.

Mean value decreased by 6 finally.

Step-by-step explanation:

Total number of restaurant initially = 4

Mean number of tables in restaurants = 30

So, total number of tables in restaurants = 4×30 = 120

Now,

He buys 2 new restaurants with 15 tables and 9 tables .

So, final number of tables = 120 + 15 + 9 = 144.

And, final number of restaurants = 4 initially + 2 newly added = 6 restaurants.

Thus , final mean value of tables in restaurants = $\frac{144}{6}$ = 24.

Thus , mean value decreased by 6 finally
