Answer:

Step-by-step explanation:

1) x +22.5 = 49.25

Subtract 22.5 from both sides

x + 22.5 - 22.5 = 49.25 - 22.5

x = 26.75

Checking:  LHS = x + 22.5 = 26.75 + 22.5 = 49.25 = RHS

2) 37.2 = n - 12

Add 12 to both sides

37.2 + 12 = n - 12 + 12

49.2 = n

n = 49.2

3) 55t = 176

Divide both sides by 55
