The answer is 16 ft because 6 ft tall over 4 feet 6 inches (4.5) is equal to x (tree's height) over 12 ft. You cross multiple and get 72 = 4.5x then you take 72 and divide by 4.5 to get the tree's height

B, parallel lines run the same direction next to each other.
Answer:
x+y=10 which means that x=10-y
Replace 10-y in the other equation which gives you:
10-y-y=6
10-2y=6
-2y=-4
y=2
Replace 2 in any of the 2 equations same answer for both:
x+y=10
x+2=10
x=8
So,


=512-8
=504
Hope this helps!
Answer:
y = 2x
Step-by-step explanation:
The equation that represents a proportional relationship that has a constant of proportionality equal to 2 is y = 2x
Answer:
- ( 17 )
Step-by-step explanation:
m = 2
n = 19
m^2
= 2^2
= 2 x 2
= 4
3m
= 3 x 2
= 6
3m - ( m^2 + n )
= 3m - ( m^2 + n )
= 6 - ( 4 + 19 )
= 6 - 23
= - ( 17 )
