(-2 + 0.8) ÷ (1²-1.3) =
(-1.2) ÷ (1-1.3)
(-1.2) ÷ (-0.3)
= 4
Cost of one hosta is $11 and one pot of ivy is $4.
Step-by-step explanation:
Let,
Cost of one hosta = x
Cost of one pot of ivy = y
According to given statement;
3x+5y=53 Eqn 1
x+7y=39 Eqn 2
Multiplying Eqn 2 by 3

Subtracting Eqn 1 from Eqn 3

Dividing both sides by 16

Putting y=4 in Eqn 2

Cost of one hosta is $11 and one pot of ivy is $4.

Answer:
69.5
Step-by-step explanation:
The useful trig relation in this case is ...
