$582.40 / 4 tires = $145.60
Answer: $145.60/tile
Answer:
Height of fir tree = 9 meters
height of pine tree= 12 meters
Step-by-step explanation:
The combined height of one fir tree and one pine tree is 21 meters. The height of 4 fir trees stacked on top of each other is 24 meters taller than one pine tree.
Let x be the height of fir tree and y be the height of pine tree

Subtract x from both sides

height of 4 fir trees = pine tree +24

Substitute 21-x or y in the above equation

Add x on both sides

Divide by 5 on both sides
x=9
Now plug in 9 for x and find out y


y=12
Height of fir tree = 9 meters
height of pine tree= 12 meters
Answer:
multiply 5 times 12 then divide by 2 which equals 30 then 15 times 36 divided by 2
Number8)4n+6-2n=2(n+3)
4n+6-2n=2n+6 then collect the like terms
(4n-2n-2n=0)
0n=0
2(3b-4)=4b-11
6b-8=4b-11 collect the like terms
(6b-4b=2b)(-11+8=-3)
answer
2b=-3 then divide both sides by 2
b=-1.5
