Answer: 2000
Step-by-step explanation:
Set up equation
The total signatures she needs is 4 times as many as she has. From this we can create the equation (4n = total signatures)
We know that the total number of signatures is 8000, so plug this into the equation to get 4n = 8000
Solve for n
Now that we have an equation, we can solve for n by dividing both sides by 4
4n = 8000
n = 8000 / 4 = 2000

Step-by-step explanation:
If the sequence is geometric then there will be a common ratio r between consecutive terms.
5 ÷ 1 = 5, 25 ÷ 5 = 5, 125 ÷ 25 = 5
Since there is a common ratio between consecutive terms the sequence is geometric.
To obtain the next term in the sequence, multiply the previous term by 5
The next 3 terms after 125 are
125 × 5 = 625
625 × 5 = 3125
3125 × 5 = 15625

Answer:
$ 850
Step-by-step explanation:
Martha and her brother started their own car-washing business.
We need to use front-end estimation to find out about how much their business will earn in 5 weeks.
Amount charged per car = $8.50
Number of cars washed per weekend = 22
Therefore, amount earned per weekend = Amount charged per car × Number of cars washed per weekend = 8.50 × 22 = $ 187
Amount earned in 5 weeks = amount earned per weekend × 5 = 187 × 5 = $ 935
Therefore, their business will earn $ 935 in 5 weeks.
