15x + 4 < 109 or -6x + 70 > - 2

For this case we must find the solution set of the given inequalities:

We subtract 4 from both sides of the inequality:

We divide between 15 on both sides of the inequality:

We multiply by -1 on both sides taking into account that the sense of inequality changes:

The solution is given by all values of x greater than -7.

Subtracting 70 from both sides of the inequality:

We divide by 6 on both sides of the inequality:

We multiply by -1 on both sides taking into account that the sense of inequality changes:

Thus, the solution set is given by:

Therefore the solution is all real numbers.

All real numbers.

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.
