Answer:
Total number of tables of first type = 23.
Total number of tables of second type = 7
Step-by-step explanation:
It is given that there are 30 tables in total and there are two types of tables.
Let's call the two seat tables, the first type as x and the second type as y.
∴ x + y = 30 ......(1)
Also a total number of 81 people are seated. Therefore, 2x number of people would be seated on the the first type and 5y on the second type. Hence the equation becomes:
2x + 5y = 81 .....(2)
To solve (1) & (2) Multiply (1) by 2 and subtract, we get:
y = 7
Substituting y = 7 in (1), we get x = 23.
∴ The number of tables of first kind = 23
The number of tables of second kind = 7
The table of the number of customers illustrates two different patterns
Deli should expect 90 customers to serve during week 8
<h3>How to determine the number of customers</h3>
From the table, the even number of week increases by 10, while the odd number of weeks reduces by 5.
At week 6, the number of customers is 80.
So, the number of customers at week 8 is:
Week 8 = Week 6 + 10
This gives
Week 8 = 80 + 10
Week 8 = 90
Hence, deli should expect 90 customers to serve during week 8

Answer:
Nice picture
Step-by-step explanation:
utoo............
To find the integer, you must cross multiply, group the same terms, then divide both side by 2:
Solution:
4/(x-3)= 2/3
12 = 2x-6
18=2x
x= 9
6*14=84
the answer is 84cm²
