Answer:

The answer to your question is  He bought 7 large candles and 9 small candles.

Step-by-step explanation:

Data

Large candles = L    cost = $7

small candles = s     cost = $3

Total cost = $76

Total candles = 16

Process

- Write two equations

                                    L  +  s  =  16     ------------ (I)

                                   7L +  3s = 76    ------------- (II)

- Solve the system of equations by elimination

  Multiply equation I by -7

                                 -7L - 7s = -112

                                  7L  + 3s = 76

Simplify

                                    0 - 4s = - 36

Solve for s

                                            s = -36 / -4

                                            s = 9

Substitute s in equation I

                                  L  + 9 = 16

Solve for L

                                  L = 16 - 9

                                   L = 7

5x+21+178/(x-7)<br> How do I solve for domain and range on this equation?
Luda [366]
The domain is easiest. You simply need to find the fractions, and exclude any X that makes the denominator zero. So in this case, your domain is everything except X=7.

For range, you are trying to find out what are the possible answers. Usually the best way to do this is to try x=infinity, and x=negative infinity, which here gives you answers of infinity and negative infinity. Since the function is almost continuous, I think your range is any real number.

A rope which is 10.3 centimeters long is cut into 4 pieces of equal length. Write an equation to find the length of
alexdok [17]

Answer: x = 10.3 ÷ 4

Step-by-step explanation: if we were to work this out forgetting about the equation it can be worked out by dividing the 10.3 by 4 to find the length of the pieces so, now to express it as an equation, we have to add x into our sum 4 × ? = 10.3 : 4x = 10.3. The answer for x would be x = 2.58.
