A cash box of $1 and $5 bills is worth $45. The number of $1 bills is three more than the number of $5 bills. How many of each b
Softa [21]

Answer:

  • 7 $5 bills
  • 10 $1 bills

Step-by-step explanation:

If we take out the extra $3, we can group the bills into one each of $5 and $1, for a value of $6. There will be 7 such groups in the remaining $42.

That means there are 7 bills of the $5 denomination, and 3 more than that (10 bills) of the $1 denomination.

There are 7 $5 bills and 10 $1 bills.

_____

If you want to write an equation, it is usually best to let a variable stand for the most-valuable contributor. Here, we can let x represent then number of $5 bills. Then the value of the cash box is ...

  5x +(x+3) = 45

  6x = 42 . . . . . . . . subtract 3, collect terms

  x = 7 . . . . . . . . . . . there are 7 $5 bills

  x+3 = 10 . . . . . . . . there are 10 $1 bills

You may notice that this working parallels the verbal description above. (After we subtract $3, x is the number of $6 groups.)

Find the center and the radius of the circle with the equation .
Simora [160]

We have been given an equation of circle x^2+2x+y^2-2y-14=0. We are asked to find the center and radius of the circle.

First of all, we will write equation of circle is standard form (x-h)^2+(y-k)^2=r^2, where center of circle is at point (h,k) and radius is r.

Let us complete the square for both x and y.

x^2+2x+y^2-2y-14+14=0+14

x^2+2x+y^2-2y=14

Adding half the square of coefficient of x and y term, we will get:

(\frac{2}{2})^2=1^2=1

(\frac{-2}{2})^2=(-1)^2=1

x^2+2x+1+y^2-2y+1=14+1+1

(x+1)^2+(y-1)^2=16

(x-(-1))^2+(y-1)^2=4^2

Therefore, the center of the circle is (-1,1) and radius is 4 units.
