Step-by-step explanation:
The original number is x.
The new number is 3x + 5.
We know that 0.5(3x + 5) = 16, so 3x + 5 = 32.
3x + 5 = 32, 3x = 27, x = 9.
Hence the original number is 9.
I’m pretty sure it’s number two in my opinion
... that there is a fairly strong, positive correlation between the variables x and y.
Answer:
3 Years
Step-by-step explanation:
Tree A can be represented by the expression (48+17x) 48 inches in 4 feet, and Tree B can be represented by (84+5x) 84 inches in 7 feet.
When you plus in 3 to both equations you will get 99 inches at each tree when they are 3 years old.
