Warm Up: Writing expressions

Learning Goal: 1.4 You will translate verbal sentences into equations or inequalities

Independent Practice – NO A.T.

WARM UP: Turn to page 20 in your textbook. Do problems 38-46 in the MIXED REVIEW, then 1-10 in the QUIZ for Lessons 1.1-1.3. You have 20 minutes to complete these problems, then we will go over then as a class.

the same as

fewer thanat most, no more than

more than

at least, no less than

PRACTICE: Translate each verbal sentence into an equation or inequality.

Verbal Sentence Equation or Inequalitya. The difference of twice a number k and 8 is 12

b. The product of 6 and a number n is at least 24

c. The sum of a number y and 5 is no more than 13

2𝑘−8=12

6𝑛≥24

𝑦+5≤13

PRACTICE: Translate each verbal sentence into an equation or inequality.

Verbal Sentence Equation or Inequalitya. The sum of twice a number r and 3 is 11

b. The quotient of a number n and 2 is at most 16

c. A number q is at least 5

2𝑟+3=11

𝑛2≤16

𝑞≥5

CHECKING FOR POSSIBLE SOLUTIONS: Check whether 3 is a solution of the equation.

Substitute 3 for x ???

Multiply ???

Subtract YES!!!!

Therefore 3 IS A SOLUTION to the equation !!

CHECKING FOR POSSIBLE SOLUTIONS PRACTICE: Check whether 3 is a solution of the equation or inequality.

a. ? ?

No, 3 is not a solution

b. ? ?

No, 3 is not a solution

c. ? ?

YES!Yes, 3 is a solution
