Answer:
Teacher is 27 years old
Step-by-step explanation:
(1/2)(t - 3) = (1/3)(t + 9)
multiply by 6 to clear the fraction
3(t - 3) = 2(t + 9)
Distribute
3t - 9 = 2t + 18
Subtract 2t from both sides
t - 9 = 18
Add 9 to both sides
t = 27

Answer:
x = 911.25
Step-by-step explanation:
let the number be x
by putting the word problem in equation, we get :
- 80/100 × x = 135/100 ×540
- 4/5 × x = 135/10 × 54
- x = 135/10 × 54 × 5/4
- x = 911.25
