333 erasers cost \$4.41$4.41dollar sign, 4, point, 41. Which equation would help determine the cost of 444 erasers? Choose 1 ans
Rudiy27

Answer:

Option D will be correct.

Step-by-step explanation:

The 333 erasers cost $4.41.

We have to determine the cost of 444 erasers.

Let the price of 444 erasers is $x.

Therefore, since the number of erasers cost per dollars is constant, hence the equation that would help to determine the cost of 444 erasers will be \frac{333}{4.41} = \frac{444}{x}

⇒ \frac{3}{4.41} = \frac{4}{x}

Therefore, option D will be correct. (Answer)

Solve, using linear combination.
Bingel [31]

Multiply the first equation by -1 to get  -4x - y = --5

Then add the second equation               3x + y = 3    

                                                           + ____________  

                                                                  -x = -2  or x = 2


then plug in 2 for x in one of the equations and solve for y      4(2) + y = 5  

                                                                                                          8 + y = 5

                           Subtract 8 from both sides                                        y = -3


                             So x = 2, y = -3     or (2,-3)
