5 years
Step-by-step explanation:
1. if able's age is x, then his sister's is x-4, and his brother's is 2x
2. if these sum to 32, then we can formulate the equation x+(x-4)+2x=32
3. now solve for x, 4x-4=32, 4x=36, x=9
4. if able's sister is x-4 years old, she is 9-4, or 5 years old
Answer:
x = 2
Step-by-step explanation:
3 3/8+4 5/7x=12 45/56
Solve :
3 3/8+4 5/7x=12 45/56
27/8 + 33/7 x = 717/56
33/7 x = (717 - 189) / 56
33/7 x = 528/56
x = 2
