Using n to represent the unknown number, which statement matches the equation 2n – 5 = 25?

5 is subtracted from a number to give an answer of 25.

A number is doubled then subtracted from 5 to give an answer of 25.

A number is doubled then 5 is subtracted from this result to give an answer of 25.

5 is subtracted from a number and the result is doubled to give an answer of 25.

Which equation represents the following statement?

A number is added to 5, then the result is divided by 4 to give an answer of 1.

(n + 5)/4 = 1

n + 5 / 4 = 1

(n + 5) – 4 = 1

4(n + 5) = 1

Entry to a fun park for children costs $15 plus $3 for every ride. Mikayla takes $75 to the park.

If r represents the number of rides, which equation matches this information?

r + 15 = 75

3r + 15 = 75

15r + 3 = 75

75 + 3r = 15
