Which of these strategies would eliminate a variable in the system of equations?
( 10x + 4y = -2)
(5x-2y=2)
Choose all answers that apply:
Multiply the top equation by
then add the equations.
Multiply the bottom equation by 2. then subtract the bottom equation from the top equation.

Add the equations.

The value of x is 0.1 and y is -0.75, if the given equations are and .

Step-by-step explanation:

The given is,

                              .................................(1)

                                  ..................................(2)

Step:1

          Equation (2) is multiplied by -2                    ( Eqn(2) × -2 )

                               ................................(3)

Step:2

          Substrate the equation (1)  and (3),

           ( - )

                                                 = 0.1

                                               x = 0.1

Step:3

            Substitute the value of x in equation (1),

          Where, x = 0.1

Step:4

       Check for solution,

                                               2 = 2

Result:

           The value of x is 0.1 and y is -0.75, if the given equations are and .

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
