C is the best one I'm pretty sure it makes the most sense
Just substitute x = 2 and y = 5 into the equation wherever you see x and y.
2 + (12 - 5x) · 2y
2 + (12 - 5(2)) · 2(5)
2 + (2) · 10
4 · 10
40, is the answer which should be the first box.
Answer:
3/8
Step-by-step explanation:
1- 1/4 +(1/2 x 3/4)
1. subtract 1/4 to get 3/4 (how much time she has left in class).
2. multiply 3/4 by 1/2 to find how much half of 3/4 is.
3. Half of 3/4 is 3/8 so that's how much time she spent on the balance beam.
