k > - 6

Interval Notation

(- 6, \infty)

Solution steps

3.9 (k + 4.2) + 3.5 k > 0.6 (7.8 k + 0.1)

Expand

3.9 (k + 4.2) + 3.5 k : 7.4 k + 16.38

Expand

0.6 (7.8 k + 0.1) : 4.68 k + 0.06

7.4 k + 16.38 > 4.68 k + 0.06

Move

16.38

to the right side

7.4 k > 4.68 k - 16.32

Move

4.68 k

to the left side

2.72 k > - 16.32

Divide both sides by

2.72

k > - 6

x^{2} - 5 = 73

\frac{4 ^{12}}{4 ^{6}}

9 (x + 5) = 72

\frac{9 !}{3 !}
