8k + 2m = 3m + k
Reorder the terms:
8k + 2m = k + 3m
Solving
8k + 2m = k + 3m
Solving for variable 'k'.
Move all terms containing k to the left, all other terms to the right.
Add '-1k' to each side of the equation.
8k + -1k + 2m = k + -1k + 3m
Combine like terms: 8k + -1k = 7k
7k + 2m = k + -1k + 3m
Combine like terms: k + -1k = 0
7k + 2m = 0 + 3m
7k + 2m = 3m
Add '-2m' to each side of the equation.
7k + 2m + -2m = 3m + -2m
Combine like terms: 2m + -2m = 0
7k + 0 = 3m + -2m
7k = 3m + -2m
Combine like terms: 3m + -2m = 1m
7k = 1m
Divide each side by '7'.
k = 0.1428571429m

k = 0.1428571429m</span>
Answer:
4 years
Step-by-step explanation:
Note that:
1 foot = 12 inches
1 2/3 feet = x inches
We cross multiply
1 foot × x inches = 1 2/3 feet × 12 inches
x inches = 1 2/3 feet × 12 inches/1 foot
x inches = 5/3 × 12 inches
x inches = 20 inches
A tree grows 5 inches each year. How many years will it take for the tree to be 1 2/3 feet tall = 20 inches
This is calculated as
5 inches = 1 year
20 inches = x year
Cross Multiply
5x = 20 inches × 1 year
x = 20/5
x = 4 years
It would take the tree 4 years to be 1 2/3 feet tall
I’m pretty sure it’s the last one
The solution or
the answer is x=1
Answer:
the answer is the second one
