Answer:
50
Step-by-step explanation:
p/5=10
Your main goal is to isolate p
p/5 = 10, in order to eliminate the 5, multiply 5 on both sides, since it's the inverse of division.
(5)p/5 = 10(5)
p=50

<span>You only need an estimate? Great. Think of the necessary material as 6 yards, so ten costumes would take 60 yards. Then think of the fabric on hand as 240 yards, so taking 60 yards away from that would leave [an estimated] 180 yards of fabric.
For an equation, use:
F" = F' - 5.8 C
Where F' is the initial fabric stock, F" is the remaining fabric, and C is the count of costumes.
In exact numbers, the formula works out to:
F" = 238.2 - (5.8 * 10)
F" = 180.2
The estimate was very close.
Good luck.</span>

Step-by-step explanation:
negative divided by a negative is positive
Answer:
The equation for this circle is 2c(x²+y²) - 8cx + cy = 0
Step-by-step explanation:
We can solve this problem replacing each of the points in the general equation and then solving the system of equations.
The fact that the circle passes by the point (3,-2) means that when x = 3, y = -2. So:
For (1, -2)
For (0,0)
Now we have to find a,b,c, from the following equations
13a+ 3b - 2c = 0
5a + b - 2c = 0
Since we have variables and 2 equations, i am going to write a and b as functions of c.
13a + 3b = 2c
5a + b = 2c
I will write b in the second equation as a function of a and c, and replace in the first equation
b = 2c - 5a
---------
13a + 3(2c-5a) = 2c
13a + 6cc -15a = 2c
-2a = -4c *(-1)
2a = 4c
a = 2c
-----------
b = 2c - 5a
b = 2c - 5(2c)
b = -8c
The solution for the system is (a,b,c) = (2c, -8c, c). So the equation for this circle is 2c(x²+y²) - 8cx + cy = 0
