Answer:

1000 bills = 7

500 bills = 19

Step-by-step explanation:

x=number of 1000 bills

y= number of 500 bills

(you can even invert them, no problem)

the system is

x + y = 26

1000x + 500y = 16500

therefore

x=26-y

using this value in the next equation

1000*(26-y) + 500y = 16500

26000 - 1000y + 500y = 16500

-500y = - 9500

y=9500/500= 19

x=26-19= 7

When 10b =5 (√c+2) is solved for c one equation is c= (2b-2) ^2 which of the following is an equivalent to find c
Ghella [55]
I will show all the steps to lead to the solution.

1) 10b = 5 (√c + 2)  <---- starting equation

2) divide by 5 => 2 b = √c + 2

3) subtract 2 => 2b - 2 = √c

4) raise to the power 2 => (2b - 2)^2 = c, which is the expression given.

Now these are two equivalent forms:

1) extract 2 from the parentheses: c = 4 (b -1)^2

2) expand the parentheses: c = 4b^2 - 8b + 4)
