3:5=x:50
Therefore 5 ×x = 50
x = 10
Therefore 3 × 10 = 30
therefore 30 blue pens
proof = 30 blue + 50 red= 3+ 5
therefore 80 = 8x
Answer:
15
Step-by-step explanation:
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.
