Creating/Solving Equations (English)

The product of 12 and a number is the same as 2 removed from a number

• 12x=x+2
• 12x=2-x
• 12-2=x-2
• 12x= x-2

A​ town's population is 47,500. About 75 people move out of the town each month. Each​ month, 125 people on average move into town. A nearby town has a population of 50,250. It has no one moving in and an average of 200 people moving away every month. Which equation can be used to determine when the population in each town will be equal?

• 125m-75m+50,250=47,500-200m

• 75m-125m+ 50,250 = 47,500-200m

• 75m-125m+47,500 = 50,250-200m

• 125m-75m+47,500 = 50,250-200m

x/9=28

• 9 times a number is 28
• A number multiplied by 9 equals 28
• A number removed from 9 is 28
• The quotient of 9 and a number is 28

Rayshawn and Robert are both saving money for their summer vacations. They began saving at the same time. Rayshawn started with $10.25 and adds $5.15 to his savings every month. Robert did not have a starting amount but adds $10.25 to his savings every month. Which equation could be used to determine how many months, m, it will take before Rayshawn and Robert both have saved the same amount of money?

• 5.15m + 10.25 = 10.25m
• 10.25m + 5.15 = 10.25m
• 10.25m + 10.25 = 5.15m
• 10.25m – 5.15 = 10.25m

The bill for the repair of a computer was $175. The cost of parts was $44, and labor charge was $45 per hour. How many hours did it take to repair the computer?

What is the correct equation to solve?

• 44h + 45 = 175

• 44 + 45h = 175

• 44 + 175 = 45h

• 44 + 45 = 175h

The sum of the measures of the angles of all triangles is 180 degrees. If one angle of the triangle measures 40 degrees. The measure of the other 2 angles is equal. What is the measure of the other 2 angles?

What is the correct equation to solve?

• 180 + 2a = 40

• 40 + 2 = 180a

• 40a + 2 = 180

• 40 + 2a = 180
