I can't read it very well but one equation might be
2x + 8 = 3x - 12
(because the opposite sides of a parallelogram are congruent.
Answer:
y = 6 + 4x
After 4 years, the tree would be 22 ft tall.
Step-by-step explanation:
Hi there!
Let x = the number of years that pass
Let y = the height of the tree (ft)
We're given that the 6-foot tree grows at a rate of 4 ft per year. This means that the height of the tree will be equal to 6 ft, the original height, plus another 4 ft every year that passes.
Height of tree = 6 feet + 4 feet × number of years that pass
y = 6 + 4x
To solve for how tall the tree would be 4 years after Dina plants it, replace x with 4, since 4 years have passed:
y = 6 + 4(4)
y = 6 + 16
y = 22
Therefore, the tree would be 22 ft tall.
I hope this helps!
Answer:
11
Step-by-step explanation:
11,16,12,7,23,9,5,5
arrange to least to greatest
5,5,7,9,11 ,12,16,23
2 middle numbers
11+12= 23
23÷2= 11.5
Median is 11
Distance=speed x time
so it would be 28 x 6=168
