<em> 24 mph</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>Vm = 21mph</em>
<em>V1 = 18mph</em>
<em>V2 = ?</em>
<em>Vm = (V₁ + V₂)/2</em>
<em>2Vm = V₁ + V₂</em>
<em>V₂ = 2Vm - V₁</em>
<em>replace Vm ; V₁</em>
<em>V₂ = 2×21mph - 18mph</em>
<em>= 42mph - 18mph</em>
<em>= 24 mph</em>
<em>Good luck !</em>
Answer:they must collect $127.75 each week
Step-by-step explanation:
The total amount of money that the sixth grader has collected so far for a local animal shelter is $116.75.
Their goal is to collect $500.
Let x represent the minimum amount of money that they must collect each week. They have 3 weeks left. This means that the total amount of money that they can collect in 3 weeks would be
3 × x = $3x
Therefore,
3x + 116.75 = 500
3x = 500 - 116.75
3x = 383.25
x = 383.25/3
x = $127.75
