Answer:
Step-by-step explanation:
Let x represent the cost of one package of tulip bulbs.
Let y represent the cost of one bag of daffodil bulbs.
Ava bought 6 packages of tulip bulbs and 12 bags of daffodil bulbs for a total of $198. This means that
6x + 12y = 198- - - - - - - - - - - - -1
Grace spent $254 buying 14 packages of tulip bulbs and 12 bags of daffodil bulbs. This means that
14x + 12y = 254- - - - - - - - - - - - 2
Subtracting equation 2 from equation 1, it becomes
- 8x = - 56
x = - 56/-8
x = 7
Substituting x = 7 into equation 1, it becomes
6 × 7 + 12y = 198
42 + 12y = 198
12y = 198 - 42
12y = 156
y = 156/12
y = 13
Answer:
64cm^2
Step-by-step explanation:
3+1+4=8
8×8= 64cm^2
Answer:
729/64
Step-by-step explanation:
= (3/2 a^-2b^2)^2
= 3^2 b^4 / 2^2 a^4
= 9b^4 / 4a^4
Plug in a = -2 and b = -3
= 9(-3)^4 / 4(-2)^4
= 9(81) / 4 (16)
= 729/64
