Answer:
$60 for a noble fir, and $40 for a douglas fir
Step-by-step explanation:
Let x represent the number of noble fir trees
Let y represent the number of douglas fir trees
We can set up a system of equations to solve this problem
5x + 3y = 420
12x + 9y = 1080
We can use elimination method to solve this. 9 is a multiple of 3, so we'll multiply the first equation by -3 to get...
-15x - 9y = -1260
12x + 9y = 1080
Now add them together...
-3x = -180 now solve for x...
x = 60
If x = 60, them
5(60) + 3y = 420 now solve for y
300 + 3y = 420
3y = 120
y = 40

ummmm is it meant to ask in 2 years instead of into years? if so
Answer:
250.50 - 35m = 300 - 45.25m
Step-by-step explanation:
Whenever an equation asks for when it will take x (or m in this case) amount of things or time you should know that there will be 2 different equations that have to equal each other
The equation will be 250.50 - 35m = 300 - 45.25m
The 35m is being subtracted from 250.50 because they are losing money each time they spend. This also applies to 45.25m
Also 35m and 45.25m are variables because it says they spend that much money each month. They don't specify how many months, so we have to put a variable after it.
