The cost of one rose bush is $2 and one day lily is $10.
Step-by-step explanation:
Let,
Cost of one rose bush = x
Cost of one day lily = y
According to given statement;
7x+6y=74 Eqn 1
7x+y=24 Eqn 2
Subtracting Eqn 2 from Eqn 1
Dividing both sides by 5
Putting y=10 in Eqn 1
Dividing both sides by 7
The cost of one rose bush is $2 and one day lily is $10.

Volume of square pyramid = a²h / 3
Surface area of square pyramid = a² +2a √((a²/4) + h²)
a = base edge
h = height
for the large pyramid;
volume = 648 m³
height = 24 m
Volume = a²h / 3
648 m³ = a² x 24 m / 3
a² = 81 m²
a = 9 m
by applying surface area equation to the large pyramid,
surface area = a² +2a √((a²/4) + h²)
= 9² + 2 x 9 √((9² / 4 ) + 24²
= 520.53 m²
hence surface area of large pyramid = 520.53 m²

The number in the field will be 
Step-by-step explanation:
To divide two fractions, we reciprocate the second fraction.
÷ 
When we reciprocate,
- The division sign turns into a multiplication sign.
- The numerator of the second fraction becomes the denominator
- The denominator of the second fraction becomes the numerator
So, the complete expression would be,
So, the number in the field will be .
