Five less than twice a number is equivalent to 47. 

• 5 - 2x = 47 

• 2x - 5 = 47 

• 5x - 2 = 47 

• 2 - 5x = 47 

Three times the sum of a number and 7 is equivalent to 57. 

• 3x + 7 = 57 

• 3(x + 7) = 57

• 7x + 3 = 57 

• 7(x + 3) = 57

In a pasture, there are horses and chickens. If there are a total of 28 animals and 80 legs, how many chickens and horses are there?

For a show, a band will be paid $150 plus $5 for each ticket sold.  Write an equation for their total payment (p) related to the number of tickets they sell (t).

• p = 150 + 5t

• p = 5 + 150t

• p + 5t = 150

• 5t - 150 = p

Lindsay had $40. She works at the grocery store and earns $15 each day.
Which equation shows the relationship between Lindsay's savings (y) and the number of days Lindsay works (x)?

• y = 15x + 40

• x = 15y + 40

• y = 40x + 15

• y = 40 - 15x
