After simplifying, which expressions are equivalent? check all that apply.

(3.4a – 1.7b) + (2.5a – 3.9b)

(2.5a + 1.6b) + (3.4a + 4b)

(–3.9b + a) + (–1.7b + 4.9a)

–0.4b + (6b – 5.9a)

5.9a – 5.6b

Asix-sided die of unknown bias is rolled 20 times, and the number 3 comes up 6 times. in the next three rounds (the die is rolled 20 times in each round), the number 3 comes up 6 times, 5 times, and 7 times. the experimental probability of rolling a 3 is 10 %, which is approximately % more than its theoretical probability. (round off your answers to the nearest integer.)
