A quarter and a dime are equal to 25 cents and 10 cents, respectively. Let x and be the number of quarter and dime coins. The equations that best expressed the condition are,
                                         x + y = 29
                                   0.25x + 0.10y = 5

The values of x and y are equal to x = 14 and y = 15. Thus, the answer is letter A. 15 dimes and 14 quarters.

For which rational expression is –2 an excluded value of x?
Kipish [7]

Answer:

option a is the answer

Step-by-step explanation:

put the value of x in each expression as x = -2

you'll see that in option a the expression becomes

\frac{x - 3}{ {x}^{2}  - 4}   =   \frac{ - 2 - 3}{ {( - 2)}^{2}  - 4}  \\  =  \frac{ - 5}{4 - 4} \\  =   \frac{ - 5}{0}

which is not defined. hence -2 is excluded value
