Use One Step Equations to Solve a Variety of Problems

How many packages of diapers can you buy with $40 if one package costs $8? (What is the unknown and what would be the equation?)

• n= # of diapers; 8n = 40
• n= # of packages; 8n = 40
• n= # of packages; 8 - n = 40
• n= # of packages; 8/n = 40

Last Friday Trevon had $29. Over the weekend he received some money for cleaning the attic. He now has $41. How much money did he receive? (What is the unknown and what would be the equation?)

• n=amount of $ Trevon received; 29 - n = 41
• n=# of days; 29 + n = 41
• n=amount of $ Trevon received; 29 + n = 41
• n=amount of $ Trevon received; 29 + n = 40

After paying $5.12 for a salad, Norachai has $27.10. How much money did he have before buying the salad? (What is the unknown and what would be the equation?)

• n=amount of $ he had at 1st; n + $5.12 = $27.10
• n=amount of $ he had at 1st; n - $5.12 = $27.10
• n=cost of the salad; n - $5.12 = $27.10
• n=amount of $ he had at 1st; $5.12 - n = $27.10

Find the missing angle.

• 40 + x = 180

• 40 - x = 90

• 40 + x = 90 x= 50

• 2x = 180

• 62 + x = 118

• 62 -x =180

• 62 + x = 90

• 62 -x =90

Find the measure of the indicated angle.

• 110 + 25 + 2x = 90

• 110 - 25 +x = 180

• 110 + 25 + x = 90

• 110 + 25 + x = 180

Find the missing angle.

• 110 -72 -80 + x = 180

• 110 + 72 + 80 + x =180

• 110 + 72 + 80 + x = 360

• 110 +72 +80 + x = 90
