A cashier collects 124 bills totaling $920 dollars. Assuming that the cashier collects $5, $10, and $20 bills, and that she coll
musickatia [10]
Let the no. of $10 bills be x, the no. of $5 bills be 2x, and the no. of $20 bills be y.

<span>A cashier collects 124 bills => x + 2x + y = 124  => 3x +y =124

</span>totaling $920 dollars => ($10)(x) + ($5)(2x) + ($20)(y) = $920 => 20x + 20y = 920

Now you got 2 equations :
3x +y =124 &
20x + 20y = 920

3x +y =124 => y=124-3x
Then Sub y=124-3x into 20x + 20y = 920,
ie. 20x + 20(124-3x) = 920 
     20x + 2480 - 60x = 920
     2480 - 40x = 920
      2480 - 920 = 40x
               1560 = 40x
                      x = 39

Given the polynomial, 8x^2 + 3x - 5, identify the following:
vovikov84 [41]

Answer:

Part A) The polynomial has three terms

Part B) The terms are  8x^{2} , 3x\ and\ -5

Part C) Is a 2nd degree polynomial

Part D) The name of the polynomial is a 2nd degree trinomial

Step-by-step explanation:

we know that

Polynomials can be classified two different ways - by the number of terms and by their degree.

we have

8x^{2} +3x-5

The polynomial has three terms

The terms are

8x^{2} , 3x\ and\ -5

therefore

The polynomial is a trinomial

The degree of the polynomial is found by looking at the term with the highest exponent on its variable(s).

The term is 8x^{2}

The highest exponent is the 2 so this is a 2nd degree polynomial

therefore

The name of the polynomial is a 2nd degree trinomial
