ASSOCIATED WORDS =
is equal to
the same as
<
is less than
fewer than
at most, no more than
is less than or equal to ≤
>
is greater than
more than
is greater than or equal to
at least, no less than ≥

5. PRACTICE: Translate each verbal sentence into an equation or inequality.
Verbal Sentence Equation or Inequality
a. The difference of twice a
number k and 8 is 12
The product of 6 and a number n is at least 24
The sum of a number y and 5 is no more than 13
2𝑘−8=12
6𝑛≥24
𝑦+5≤13

6. PRACTICE: Translate each verbal sentence into an equation or inequality.
Verbal Sentence Equation or Inequality
The sum of twice a number r
and 3 is 11
The quotient of a number n and 2 is at most 16
A number q is at least 5
2𝑟+3=11
𝑛 2 ≤16

7. Therefore 3 IS A SOLUTION to the equation 𝟖−𝟐𝒙=𝟐!!
CHECKING FOR POSSIBLE SOLUTIONS: Check whether 3 is a solution of the equation.
8−2𝑥=2
Substitute 3 for x −2 3 =2 ???
Multiply 8−6=2 ???
Subtract =2 YES!!!!
Therefore 3 IS A SOLUTION to the equation 𝟖−𝟐𝒙=𝟐!!

8. CHECKING FOR POSSIBLE SOLUTIONS PRACTICE: Check whether 3 is a solution of the equation or inequality.
a 𝑥−5=6
4 3 −5=6 ?
12−5=6 ?
7≠6
No, 3 is not a solution
b 𝑧+5>12
2 3 +5>12 ?
6+5>12 ?
11≯12
No, 3 is not a solution
c 𝑛≤20
5+3(3)≤20 ?
5+9≤20 ?
14≤20 YES!
Yes, 3 is a solution
