15. The answer that best fits the question would be the "First" option. the ( and ) are just things to say do the inner work first, then multiply.
16. The Third option is the answer that best fits the question. She is trying to find how many time she did something, so multiplication would be the answer.

Answer:
10
Step-by-step explanation:
The answer is 10 because there are five stacks of 2 cubes. 5 x 2 = 10.
Combine the common factors.
11x + 5 = 180
Subtract 5 from both sides.
11x = 175
Divide 11 from both sides to isolate the x.
x = 15.90909091
