There are a total of 15 dimes and quarters in a covered cup. The value of all 15 coins totals 2.85
QveST [7]

Answer:

There are 6 dimes and 9 quarters.

Step-by-step explanation:

Represent the number of dimes and the number of quarters by d and q.

Then d + q = 15, or q = 15 - d.

Also, ($0.25)q + ($0.10)d = $2.85, or 5q + 2d = 57.

Substituding 15 - d for q, we get 5(15 - d) + 2d = 57, or

75 - 5d + 2d = 57, or

75 - 3d = 57, or

3d = 18.  Thus, there are 6 dimes.  Since q = 15 - d, q = 15 - 6 = 9.

There are 6 dimes and 9 quarters.

Define the value of the expression 3^2 x 3^{-5}
Tanya [424]

Answer:

Between 0 and 1

Step-by-step explanation:

The given expresion is

{3}^{2} \times  {3}^{ - 5}

Recall that:

{a}^{m}  \times  {a}^{n}  =  {a}^{m + n}

We apply this property of exponents to get;

{3}^{2}  \times  {3}^{ - 5}  =  {3}^{2 +  - 5}  =  {3}^{ - 3}

We rewrite to obtain a positive index as:

{3}^{2}  \times  {3}^{ - 5}  =  \frac{1}{ {3}^{3} }  =  \frac{1}{27}

Therefore the value of the expression is between 0 and 1.

The correct answer is:   [A]:  " 2" . 
_______________________________________________________
Explanation:
_______________________________________________________

5x - 4 = 3x ; 

Subtract "3x" from each side of the equation; 

5x - 4 - 3x = 3x - 3x ; 

2x - 4 = 0 ; 

Add "4" to each side of the equation; 

2x - 4 + 4 = 0 + 4 ; 

2x = 4 ; 

Divide each side of the equation by "2" :

2x / 2  =  4 / 2 ;

  x = 2 ;   which is:  "Answer choice:  [A]:  " 2" .
