Answer:
8 months
Step-by-step explanation:
x=# of months
45+4x=2x+61
45+2x=61
2x=16
x=8
Answer:
x ≈ 15.9
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
x² + 6² = 17²
x² + 36 = 289 ( subtract 36 from both sides )
x² = 253 ( take the square root of both sides )
x = 
≈ 15.9 ( to the nearest tenth )
4 7/8 = 4 14/16 = 78/16
2 7/16 = 39/16
39/16 + 39/16 + 39/16 + 39/16 = 156/16
78/16 + 78/16 = 156/16
156/16 + 156/16 = 312/16 = 19 8/16 = 19 1/2
Answer: 19 1/2 inches
