Answer:

x=-58/15

Step-by-step explanation:

distribute first 10-2.5x+12=21-10x-28

Simplify(add the numbers) 22-2.5x=-7-10x

move the variable to the left side 22-2.5x+10x=-7

move the constant to the right side -2.5x+10x=-7-22

simplify like terms 7.5x=-29

divide by 7.5 x=-58/15

alternate forms are x=-3 13/15 or x=-3.86

Solve the inequality<br> 3/10 ≥ k - 3/5

balandron [24]

Answer:

The answer to your question is $k \leq \frac{9}{10}$ or (-∞ , 9/10]

Step-by-step explanation:

To solve inequality is similar to solve and equation, we just need to find the values of "k" in order than the inequality be true.

$k - \frac{3}{5} \leq \frac{3}{10}$

Solve for "k"

$k \leq \frac{3}{10} + \frac{3}{5}$

$k \leq \frac{3}{10} + \frac{6}{10}$

$k \leq \frac{9}{10}$

Then the answer is

$k \leq \frac{9}{10}$ or (-∞ , 9/10]
