Answer:
Cost of one apple pie is $12.50 and cost of one lemon merigue pie is $8.75
Step-by-step explanation:
Let,
x be the cost of each apple pie
y be the cost of each lemon merigue pie
According to given statement;
5x+2y=80 Eqn 1
3x+6y=90 Eqn 2
Multiplying Eqn 1 by 3
3(5x+2y=80)
15x+6y=240 Eqn 3
Subtracting Eqn 2 from Eqn 3
(15x+6y)-(3x+6y)=240-90
15x+6y-3x-6y=150
12x=150
Dividing both sides by 12
Putting x=12.50 in Eqn 1
5(12.50)+2y=80
62.50+2y=80
2y=80-62.50
2y=17.50
Dividing both sides by 2
Hence,
Cost of one apple pie is $12.50 and cost of one lemon merigue pie is $8.75
Answer:
64 pi
Step-by-step explanation:
Area of a circle is pi(r) ^ 2
The radius is half the diameter, so it would be 8 mi.
Pi ( 8 ) ^ 2
Pi ( 64 )
It would be 64 pi
Answer: 9 x 3 = 27
9 times 3 is equal to 27
Step-by-step explanation:
by comparing both f (x) and g (x)
we get
3x-1=2x-1/x
by this way we can get the value of X and put the value of X in f (x) and g (x)
