You can solve this with proportion

40 : 60 = 3 : x  => 40x=180 => x = 180/40 = 4.5 seconds

Good luck!!!!

The equation for this problem would be,
s = seconds
f = feet
s * 20 = f
So the elevator travels,
s           f
1           20
2          40
3          60
4          80
5          100

What is a number mulitplyed by 8 and added by 6?
HACTEHA [7]
Xy = 8
x + y = 6

     x + y = 6
x - x + y = -x + 6
           y = -x + 6

                                 xy = 8
                       x(-x + 6) = 8
                   x(-x) + x(6) = 8
                        -x² + 6x = 8
                   -x² + 6x - 8 = 0
     -1(x²) - 1(-6x) - 1(8) = 0
              -1(x² - 6x + 8) = 0
                          -1           -1
                    x² - 6x + 8 = 0
             x² - 4x - 2x + 8 = 0
 x(x) - x(4) - 2(x) + 2(4) = 0
           x(x - 4) - 2(x - 4) = 0
                  (x - 2)(x - 4) = 0
      x - 2 = 0    or    x - 4 = 0
        + 2 + 2             + 4 + 4 
           x = 2       or      x = 4

   x + y = 6
   2 + y = 6
 - 2        - 2
         y = 4
   (x, y) = (2, 4)

           or
    x + y = 6
    4 + y = 6
  - 4        - 4
          y = 2
    (x, y) = (4, 2)

The two numbers that add up to 6 and multiply to 8 are 4 and 2.

Find the common factor of the given terms 6a^3 b^2 c, 24ab^3 c^4 , 12 abc​
Pachacha [2.7K]

Answer:

Step-by-step explanation:

the way you do it is by checking the letter in every term and seeing which instance has the lowest of that letter (for now pretend the regular numbers, in this case 6 24 and 12, aren't there). Once you do that you'll see that the last term has each variable (letter) to the power of one, so that will be the common factor for the letters. Next, look at the real numbers, and you see that the lowest number each can be divided by is 6. so you have 6abc. I'm tired and I think I explained it in a confusing way, so if you still have questions search up "how to find the greatest common factor in polynomials"
