Oliver has 15 colored rocks.

Mason has 12 more colored rocks than Oliver has.

Wyatt has twice as many colored rocks as Mason.

Which equation can be used to find m, the number of rocks that Wyatt has?

• 15 x 2 = 30, 30 x 2 = m

• 15 + 12 = 27, 27 x 2 = m

• 15 + 12 = 27, 27 + 2 = m

• 15 – 12 = 3, 3 x 2 = m

• 3 x 19 = 57, 2 x 15 = 30, 57 + 30 = t

• 2 x 19 = 38, 3 x 15 = 45, 38 – 45 = t

• 2 x 19 = 38, 3 x 15 = 45, 38 + 45 = t

• 2 x 19 = 38, 3 x 15 = 45, 38 x 45 = t

• 45 x 3 = 135, 135 + 24 = x

Bella met her goal of running 27 miles in 3 days. On the first day, she ran 9 miles. She ran 12 miles on the second day. Which equation can be used to find n, the number of miles she ran on day 3?

• n = 27 + 9 + 12

• n = 27 + 9 - 12

• n = 27 - 9 + 12

• n = 27 - 9 - 12
