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
Final Answer
Fiona has collected 2000 signatures so far
It’s the first one.............
Use the ticket price in the first column in the formula 400-7p to get the answer for the second column (number of tickets sold)
Then multiple the number to f tickets in the second column by the price in the first to determine the revenue.
Answer:
And if we solve for y we got:
And replacing we got:
And we got:
And for x we got:
So then the length would be 76 and the width we got 12.5
Step-by-step explanation:
For this case we have a rectangle. The perimeter is given by:
Where x represent the length and y the the width. We can set the following conditions:
And if we replace the conditions we got:
And if we solve for y we got:
And replacing we got:
And we got:
And for x we got:
So then the length would be 76 and the width we got 12.5
The answer is (-160) because you need to plug in the numbers for the equation 6 times
