Answer:the cost of renting one chair is $2.25
the cost of renting one table is $8.25
Step-by-step explanation:
Let x represent the cost of renting one chair.
Let y represent the cost of renting one table.
The total cost to rent 3 chairs and 5 tables is $48. This means that
3x + 5y = 48 - - - - - - - - - -1
The total cost to rent 6 chairs and 2 tables is $30. This means that
6x + 2y = 30 - - - - - - - - - -2
Multiplying equation 1 by 6 and equation equation 2 by 3, it becomes
18x + 30y = 288
18x + 6y = 90
Subtracting, it becomes
24y = 198
y = 198/24 = 8.25
Substituting y = 8.25 into equation 1, it becomes
3x + 5 × 8.25 = 48
3x + 41.25 = 48
3x = 48 - 41.25 = 6.75
x = 6.75/3 = 2.25
Answer: 68n+11
Step-by-step explanation:
2(9n+8)-5(-10n+1)
(18n+16)-(-50n+5)
18n+16+50n-5
68n+11
2.1-2p= -4.7
they said the difference of 2.1 and twice a number p. which I'm assuming letter p, but anyway. difference means subtraction and twice mean multiplication so 2p
that's why we have 2.1-2p= -4.7
