The correct result would be 154.
Answer:
Question 5: y = - 
x + 6
Question 6: y = 
x + 100
Question 7: y = -10x + 45
14 = 7*2
63 = 7*9
14 7 * 2 2 2
---- = ------- 7/7 =1, so = 1 * ------ = ----
63 7 * 9 9 9
12-7=5
all you have to do it subtract the number of pens from the number of pencils
3 tables are 4-seated table and 4 tables are 6-seated table.
<u>Step-by-step explanation</u>:
Let us assume,
The 4 seats table be type A table and the 6 seats table be type B table.
- The number of type A seat = x
- The number of type B seat = y
- Total table rented = 7 tables
- Total people in party = 36 people
x+y = 7 --------(1)
4x+6y = 36 -------(2)
Multiply (1) by 6 and subtract (2) from (1)
6x+6y = 42
- (<u>4x+6y = 36</u>)
<u> 2x = 6 </u>
x = 6/2
x = 3
The number of 4 seated table is 3.
Substitute x=3 in (1)
3+y = 7
y = 4
The number of 6 seated table is 4.
