The sum of a number w and 3 is less than or equal to ten.

In this problem we must translate English words into Algebraic Expressions. So we have the following English words:

The sum of a number w and 3 is less than or equal to ten

So let's do that using two steps:

Here we have two numbers w and 3. So we must makes the sum these numbers, therefore:

The symbol for the English words less than or equal to is ≤ hence we can write these words as:

As you can see, the algebraic expression is an inequality.

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.
