a number is added to 22 is the same as the product of 6 and a number

• 22+u

• 22+k = 6x

• 22+u=6 + x

• u+22=6

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

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

120 more than twice a number is the same as halve a number removed from 8

• 2t+120= t⁄2-8

• 120+2t = t⁄2-8

• 2t+120 = 8-t⁄2
