Answer:
k = 4
Step-by-step explanation:
Rearrange so that like terms are on either side of the equation
4k - 2k - 2k + 2k = 5 + 3
Simplify
2k = 8
Divide both sides by two to make k on its own
k = 4
You are correct, well done!

Answer:
square foot per hour
Step-by-step explanation:
The total area covered = 34 square foot
Time taken = 12 hours
This implies that it takes 12 hours to cover 34 square foot.
Using proportionality,
12 hours ---------------------------------------> 34 square foot
Dividing both sides by 12
---------------------------> 
1 hour --------------------------------------->
square foot per hour
The unit rate in square feet per hour is
square foot per hour
<span>Given:
AB = x + 16
BC = 4x + 11
AC= 77
We can safely assume that,
AB + BC = AC
x + 16 + 4x + 11 = 77
5x + 27 = 77
5x = 77 - 27
5x = 50
x = </span>

x = 10
Hence,
AB = x + 16 = 10 + 16 = 26
Hence, proved.
