For a solution of 'all real numbers' to occur, you must end up with a statement that is true no matter what

example
simplifying results in x=x or 8=8 or 0=0 or something liek that

an example equation would be 2(x+1)=2x+2, simplifies to x=x or 2=2 or 0=0



no solution is when you get a false statement from simplifying
example, 3=4 or -1=0

an example equation could be 2(x+1)=2x+3, it simplifies to 2=3 which is false

Read the problem and answer the questions show your solution when necessary. ​
Alexandra [31]

Answer:

Step-by-step explanation:

1) Number of white chocolate bars = x

Number of dark chocolate bars = y

Total bars = 15

x + y = 15 --------------(I)

Total cost = Php. 340

20x + 25y = 340 ----------------(II)

2)  We can use elimination method to solve this equations.

Multiply equation (I) by (-20) and then add the equations.

(I)* (-20)          -20x  -20y = - 300

(II)                    <u>20x + 25y = 340 </u>     {Now add and x will be eliminated}

                                  5y = 40

                                    y = 40/5

y = 8

Substitute y = 8 in equation (I)

x + 8 = 15

      x = 15 - 8

x = 7

3) Number of dark chocolate bars = 8

The mean of a set of numbers is 8, and the mode is 9.
ryzh [129]
You can start by looking at the mode of the set of number automatically b and d are eliminated. We then proceed to calculate the mean so add all the numbers in A so it’ll be, 52 then divide by the amount of numbers in the set so 6. 52/6 =8.6
And C ends up being 48 so 48/6 = 8
Therefore your answer is C
