Answer 1

23 yards

Explanation:

During a test flight, Jeri's rocket reached a height of 18 yards. This was 7 yards less than the height of Devon's rocket. Write and solve a subtraction equation to find the height of Devon's rocket.

Let us represent the height of Devon's rocket = x

18 yards = x - 7 yards

x = 18 yards + 7 yards

x = 23 yards

The height of Devon's rocket = 23 yards
