Answer:  5, 8

<u>Step-by-step explanation:</u>

The difference between 3 times a number and -8 is BETWEEN 23 and 32

Note: "difference" means subtraction --> 3x - (-8)  --> 3x + 8

               23 < 3x + 8 < 32

               15 < 3x        < 24          <em> subtracted 8 from all 3 sides</em>

-->             5 <   x        <   8          <em>divided 3 from all 3 sides</em>

What is the solution set for the inequality x &lt; -2 or x &gt; 6
bija089 [108]

he solution set is

{ x ∣ x > 1 } .


Explanation

For each of these inequalities, there will be a set of

x

-values that make them true. For example, it's pretty clear that large values of

x

(like 1,000) work for both, and negative values (like -1,000) will not work for either.

Since we're asked to solve a "this OR that" pair of inequalities, what we'd like to know are all the

x

-values that will work for at least one of them. To do this, we solve both inequalities for

x

, and then overlap the two solution set

Answer:

m MN = 70°

Step-by-step explanation:

∠MLN is an angle formed by the chords ML and LN and is calculated as

∠MLN = 0.5( m arc MN ), that is

35° = 0.5 arc MN ( multiply both sides by 2 )

arc MN = 2 × 35° = 70°
