Answer :
Answer:
what is the value of k?
4/5 k - 1/10 k = 1/2 k +1
the answer is k = 5
Step-by-step explanation:
from the question what is the value of k?
4/5 k - 1/10 k = 1/2 k +1
by rearranging, we have;
4k/5 - k/10 =k + 1/ 2
finding the lcm of the RHS which is 10
2(4k) - k/10 = k+ 1/2
8k-k/ 10 = k + 1 /2
finding the lcm of the R
LHS which is 2
we have
7k/10 = k + 2/2
by cross multiplying
14k = 10k + 20
collect the lie terms
14k - 10k = 20
4k = 20
divide both sides by 4
k = 5
