Please help, I suck at math. The Life of Trees Project

Part A: Tree Research
Five years ago your teacher planted a tree that was 24 inches tall and has tracked it's growth. You decided you want to plant a tree seed and see when both trees will be the same height.

Teacher:
Hickory (Shellbark)
10'' per year
80' when mature

Me:
White Ash
18.5'' per year
65' when mature

Part B:
Write a linear equation for each tree to represent it's growth each year. Fill in the following info to help.

Identify your variables:
x = y=

What are the variables? (find the let statement)​

what does x eaqual

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
