3x+17<47
-6x+9<25
Solve the inequalities and make a number line

Read below.

Step-by-step explanation:

Let's take the first one.

Subtract 17

Divide by 3

---------------------------------------------------------------------------------------------

Now the second one.

Here's the trick. You need to divide by -6; however, there's a rule. When you multiply or divide by negative numbers, the inequality sign flips.

---------------------------------------------------------------------------------------------

x has to be less than 10

x has to be greater than or -2.66 approximately.

in the number line, make a hollow circle on and draw an arrow up to where, again, you have to make a hollow circle. The circles have to be hollow because neither nor 10 are part of the answers.

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.
