Lets x is price of noble fir trees and y - is price for douglas fir trees
students got 5x+3y=420$ on friday
and 12x+9y=1080
now we need just solve the system of equations
5x+3y=420 - multiply by 3
12x+9y=1080
15x+9y=1260
12x+9y=1080
substract second equation from first
15x-12x=1260-1080
3x=180
x=60$ - the price of noble fir trees
put value x=60 in first equation 5x+3y=420
5*60+3y=420
300+3y=420
3y=120
y=40$ - price of Douglas fir trees
Answer: Noble fir trees cost $60 and Douglas fir trees cost $40

Answer:
a= 24b/5c b= 5ac/24 c= 24b/5a
Step-by-step explanation:
Put the problem into a calculator that can solve with variables.
C. You can plan when you a paying bills.
I think this is the answer because it does not have a direct correlation to direct deposits to me.
First, find the area of the circle
pie*radius to the power of 2(radius*raduis)
(11*11=121) 121*3.14=379.94
take your answer and divide it by 4 we would divide it by 2 if we had a semicircle but since we have a 3/4 circle we divide by 4 and then times the Quotient by 3
379.94/4=94.985
94.985*3=284.955
Round ur answer to the nearest tenth so it equals 284.96
