It should be 8 tablespoons, because 1/2 of 1 cup is 8 tablespoons.
[multiply the first equation by -2]
[-2x - 10y = 4]
[add like terms between the equations]
[-5y = 10]
[y = -2]
[x = 8]
(8, -2)
Answer:
Step-by-step explanation:
If it costs $114 per year to rent an instrument, then it costs 114/12 to rent it per month, which is $9.50.
For a rental time of 3 years and 5 months, we have 3(114) + 5(9.50) = 342 + 47.50 = $389.50
The equation that represents this total cost in terms of month rented is:
C(m) = 9.50m, where C(m) is the total cost after m, months, rented.
Answer:
x = 11/7 y = -1/7
Step-by-step explanation:
2x + y = 3
2x + y - 2y = 3 - 2y
y = 3 - 2x
x - 3(3 - 2x) = 2
x - 9 + 6x = 2
x - 9 + 6x + 9 = 2 + 9
x + 6x = 11
7x = 11
7x / 7 = 11/7
x = 11/7
2(11/7) + y = 3
22/7 + y = 3
22/7 + y - 22/7 = 3 - 22/7
y = -1/7
