UNIT 2-Lesson 5-Situations for Equations and Inequalities

Which equation will help you find the solution?

• 24x + .10 < .25x
• 24 + .10x > .25x
• 24 + .10x < .25x
• (24 + .10)x > .25x

Write an equation to help you find the value of a.  

• 3a + (2a -25) = 180
• 6a - 25 = 180
• 3a = 2a - 25
• 3a > 2a - 25

(continued from the last question)
Hopefully, your equation was
3a + (2a - 25) = 180.  
What is the value for a?

• a = 205
• a = 123
• a = 41
• a = 57

Write an equation or inequality to represent the situation.  

• 55 + 4p > 110
• 55 + 4p < 110
• 55 + 4p = 110 
• 110 < 55p + 4

Write an equation to represent the situation.

• 376 + 12h > 280 + 15h 
  
• 376 + 12h < 280 + 15h 
• 376 + 12h = 280 + 15h 
• Huh?!  
  (ONLY lazy peeps pick this!)

(continued from last question)
Solve the equation 376 + 12h = 280 + 15h to find how long a job is for which both companies will charge the same amount.

• 32 hours
• 96 hours
• 3 hours
• no hours

Write an equation or inequality to match the situation.

• 312 + 12w = 36w
• 312 + 12w > 36w
• 312 + 12w < 36w
• 312 + 12w = 36

(continued from last question) 
Solve the inequality from the previous question to find out how many windows fit the situation.

• 13 windows
• w > 13
• w < 13
• w = 13

Write an inequality to represent the situation.

• 12 + 3y > 16 + 2.5 y
• 12 + 3y = 16 + 2.5 y
• 12 + 3y < 16 + 2.5 y
• 12 + 3y < nothing!

Proper name for this symbol....

• greater than
• greater than or equal to
• less than
• less than or equal to
