1) 5x - 100 x=25 2) x³ x=4 3) 2x - 20 x=5 4) 7x + 25 x=4 5) x³ + 9 x=3. 6) 4(x-5) x=20 7) 6x + y² x= 4 and y= 3 please help asap my parents took away everything and expect me to finish all of this with nothing! help! ily!

Step-by-step explanation:

For all of these problems, we are given the values of the variable x.

Now, we just need to input them into the equations.

1) 5x-100 x=25

  5(25)-100

  125-100= 25

2) x^3 x=4

   4^3= 4×4×4= 64

3) 2x-20 x=5

   2(5)-20

   10-20= -10

4) 7x+25 x=4

   7(4)+25

   28+25= 53

5) x^3+9 x=3

   3^3+9= (3×3×3)+9

   27+9= 36

6) 4(x-5) x=20

   4(20-5)

   20(4)-5(4)

   80-20= 60

7) 6x+y^2 x=4 and y=3

   6(4)+3^2

   24+(3×3)

   24+9= 33

Hope this helps! :)

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b
