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
Answer:
The area is 11317.51
Step-by-step explanation:
The sum of 2 sides must be less than the third side (largest side) for a triangle to be formed.
b+c<a
133+174 < 240
A triangle can be formed
To use Herons formula for the area
We find S = 1/2( a+b+c)
= 1/2(240+133+174)
= 1/2 (547)
= 273.5
Area = sqrt( S (S-a) (S-b)(S-c))
sqrt((273.5 ) (273.5 -240) (273.5-133) (273.5-174))
sqrt((273.5)(33.5) (140.5) (99.5))
sqrt(128085964.4)
11317.50699
The area is 11317.51
3x-7=-2-6
3x=-2-6+7
3x=-1
X=-3
Paul must get 13 since Peter gets more more than Jane so Jane would get 7 and then peter would get 12
Answer:
x = 17/2 = 8.500
Step-by-step explanation:
Equation at the end of step 1 :
2 • (x - 5) - 7 = 0
Step 2 :
Equation at the end of step 2 :
2x - 17 = 0
Step 3 :
Solving a Single Variable Equation :
3.1 Solve : 2x-17 = 0
Add 17 to both sides of the equation :
2x = 17
Divide both sides of the equation by 2:
x = 17/2 = 8.500
