Let x be the number of erasers
4 = 20
1 = x
4x = 20
x = 5
therefore there are 5 number of erasers
There all multiples of 9 so just times it by your Y axis
Answer:
4x/9
Step-by-step explanation:
Use the distance formula: d² = (x₂ - x₁)² + (y₂ - y₁)²
d² = 50² + 80²
= 2500 + 6400
= 8900
d = √8900
= 94.3
Answer: 94.3 km
