Answer:

Result for Inequality expression 1:

x < 5

Result for Inequality expression 2:

x \geq -3

Step-by-step explanation:

-Inequality expression 1:

2x - 3 < 7

-Inequality expression 2:

5 - x \leq 8

-Solve inequality expression 1:

2x - 3 < 7

2x - 3 + 3 < 7 + 3

2x < 10

\frac{2x}{2} < \frac{10}{2}

\boxed {x < 5}

-Solve inequality expression 2:

5 - x \leq 8

5 - 5 - x \leq 8 - 5

- x \leq 3

\frac{-x}{-1} \leq \frac{3}{-1}

\boxed {x \geq -3} (inequality sin changed by divide by a negative integer or variable)

<span>The first and last four numbers each have a difference of one between them. The fifth number has a difference of 10 between it and the previous number. The middle number has a difference of 20 between itself and the two numbers that surround it. Counting in this way could have been a result of a lot of things to count, and spot checking along the way (when the numbers have a difference of 1).</span>
