When you see a number that look almost the same you add or subtract
10x^2 - 3x^2
Always carry the symbol in front of the number

The cost of 6 sandwiches and 4 drinks is $53. The code of 4 sandwiches and 6 drinks is $47. How much does one sandwich cost?
Annette [7]

Answer:

$6.50

Step-by-step explanation:

SET UP A SYSTEM OF EQUATIONS WHERE SANDWHICHES IS REPRESENTED BY S AND DRINKS BY D:

6S+4D = 53

4S+6D=47

ADD THEM TOGETHER

10S+10D=100

SOLVE FOR D

10D = 100 - 10S

D = 10-S

SUBSTITUTE THAT VALUE INTO ONE OF THE ORIGINAL EQUATIONS

4S + 6(10-S) = 47

4S + 60 - 6S = 47

COMBINE LIKE TERMS

-2S + 60 = 47

SUBTRACT 60 FROM BOTH SIDES

-2S = -13

DIVIDE BY -2

S = 13/2

S = $6.50

Let x represent the time she works (in hours) and y represent the amount of membership she sells then...

8.50x+2y

How do you do this problem? Simple and concise explanation please! TOP ANSWERERS!!!!
charle [14.2K]

Answer:

Just B and C

Step-by-step explanation:

Reduce this to the lowest amount possible.

log(3abc/6a^2b) = 2

=================

log(c/2a)  = 2

c/2a = 10^2

c = 2a * 100

c = 200a

This one is also correct.

=================

The rest are just incorrect.

There is only 1 answer that works and that is B.

C is close, but it is not correct.

D is backwards. B is the right way and D is the upside down of B.

E and F are just not the way to handle logs. Subtracting logs means division, not multiplication and not 1 log.

=================
