1. y₁ = 70x
2. y₂ = 55x
Solve y₁ - y₂ for x = 11.
Answer:
1. The 
is between 3 and 4.
2. The 
is between 7 and 8.
3. The 
is between 4 and 5.
4. The 
is between 9 and 10.
5. The 
is between 6 and 7.
Step-by-step explanation:
1. : 10 is near the perfect squares 9 and 16, which would mean its answer is between their square roots which are 3 and 4.
2. : 10 is near the perfect squares 49 and 64, which would mean its answer is between their square roots which are 7 and 8.
3. : 10 is near the perfect squares 16 and 25, which would mean its answer is between their square roots which are 4 and 5.
4. : 10 is near the perfect squares 81 and 100, which would mean its answer is between their square roots which are 9 and 10.
5. : 10 is near the perfect squares 36 and 49, which would mean its answer is between their square roots which are 6 and 7.
