Answer:
The complete list of factors for 805 are 1, 5, 7, 23, 35, 115, 161, and 805.
Step-by-step explanation:
A factor pair is a combination of two factors which can be multiplied together to equal 805. In proper math terms, the number 805 is called the product and the two numbers that can be multiplied together to equal it are called the factors.
In order to work out the factor pairs of 805 we need to first get all of the factors of 805. Once you have the list of all those factors we can pair them together to list out all of the factor pairs.
The complete list of factors for 805 are 1, 5, 7, 23, 35, 115, 161, and 805.

Answer:
Let the number of nickels be x
Let the number of pennies be y
Let the number of dimes be z
Now z=x+y
FIrst equation:
z+x+y=16
Subsittue for z:
x+y+x+y=16
y=8-x (subsitution)
Hope this helps :)

Answer:
Step-by-step explanation:
Take the derivative of all terms with respect to x:
-2(dy/dx) + 16x = -7 + 18y(dy/dx). Grouping the (dy/dx) terms on the left, we get:
(dy/dx)(-2 - 18y) = -7 - 16x, or
-7 - 16x
dy/dx = ------------------
-2(1 + 18y)
Substituting 2 for x and -3 for y, we obtain the desired derivative:
-7 - 16x -7 - 32 -39
dy/dx = ------------------ = --------------- = ----------- = -0.368
-2(1 + 18y) -2(1 - 54) 106
