-12 + 5k = -925k + (-12) = -925k = -92 + 125k = 80k = -80/5k = -16
To simplify the expression 5k + 7 + 3k, first combine like terms by adding the coefficients of the k terms: 5k + 3k = 8k. Then, add the constant term: 8k + 7 = 8k + 7. So, the simplified expression is 8k + 7.
The K stands for thousand. So 5k is 5,000 and 7 3K is either 73,000 or 7,000 and 3,000.
5k + 2 = -2 Therefore, 5k = -4 k = -4/5 k = -0.8
r = 5k + 5ur - 5u = 5kk = r/5 - u
